Keep, Integrate or Replace
Updated: Oct 9
A Smart Technology Framework for Multifamily Acquisitions
By Charles Hadsell | October 2026
Smart building technology decisions in a multifamily acquisition are rarely as simple as choosing a lock, thermostat, access control system, or resident application.
An acquiring owner first needs to understand what is already installed, whether it remains useful, how well it fits the intended operating model, and whether the economics support retaining, integrating, or replacing it.
I have owned and operated rental assets for more than 20 years and have operated a smart apartment technology business for more than eight years.
During that time, I have seen properties with almost no meaningful technology infrastructure, properties with well-designed and unified technology environments, and many properties somewhere in between—with a collection of disconnected systems installed by different owners at different points in time.
That last scenario is becoming increasingly common.
The conversation has shifted from “Should we install smart technology?” to more complicated questions:
What should we do with the technology already installed?
Which systems should we keep?
Which systems can be integrated?
Which systems should be replaced?
Which investments will improve operations or the resident experience?
Which investments will generate enough revenue, savings, or risk reduction to justify the capital?
The right answer is not always to replace everything. It is also not always to preserve everything.
The objective should be to identify which systems still create value, which create operational friction, and which can be incorporated into a scalable technology strategy that supports the property’s business plan and projected net operating income.
That makes technology selection fundamentally a capital-allocation and operating-model decision, not simply a product-selection exercise.
Why Technology Decisions Are Difficult During an Acquisition
One of the biggest challenges is timing.
In many acquisitions, the pro forma is substantially developed before anyone has done a detailed review of the property’s technology infrastructure.
The acquisition team may know the property has smart locks, thermostats, access control, cameras, leak detection, intercoms, or a resident application, but it may not know:
The exact make, model, age, or condition of the equipment
Whether the systems remain supported by the manufacturer
Whether the hardware can transfer to the new owner
Whether the existing service provider can be changed
Whether existing systems can integrate with the owner’s preferred technology stack
What software agreements or subscription obligations remain in place
Whether multiple systems require separate resident credentials
What it will cost to retain, repair, integrate, or replace the equipment
Whether the financial benefits of an upgrade justify the investment
This creates a difficult underwriting problem.
A general capital allowance may be included in the acquisition model, but without a detailed understanding of the existing technology, an owner may later discover that equipment is obsolete, incompatible, unsupported, or tied to a software agreement that does not fit the new operating plan.
Technology planning should therefore begin during due diligence—even when the actual upgrade will not occur until months or years after closing.
The objective during diligence is not necessarily to design every system. It is to get enough information to make an informed capital decision.
The Core Technology Selection Criteria
Before deciding whether to keep, integrate, selectively replace, or fully replace an existing technology stack, owners should evaluate the property against several criteria.
1. Remaining Useful Life
How old is the installed equipment, and how much useful life remains?
Relatively new and reliable hardware may not need to be replaced simply because it differs from the owner’s preferred portfolio standard.
Conversely, older equipment with declining manufacturer support, high failure rates, or limited replacement parts may become increasingly expensive to operate.
The important question is not simply whether the technology works today. It is whether it is likely to remain economically viable over the owner’s anticipated hold period.
2. Interoperability
Can the existing technology work with the owner’s preferred systems?
A property may have functional smart locks, common access control, cameras, thermostats, and intercoms, but each may operate through a separate application or management portal.
The individual systems may still have considerable value if they can be tied together through integrations or a resident experience platform.
Compatibility, however, needs to be confirmed at a detailed level.
Two systems may appear compatible but still require separate credentials, separate staff workflows, different gateways, additional licensing, or specific firmware versions.
3. Operational Burden
How many platforms, vendors, logins, service agreements, and workflows are required to operate the property?
Technology can function correctly while still creating a significant operational burden.
Multiple disconnected systems can result in:
Duplicate data entry
Separate credential management
Complicated move-in and move-out procedures
Increased staff training
Confusion over which vendor provides support
Additional resident service calls
The true cost of fragmented technology is therefore not limited to software fees. It also includes staff time, training, support, and operational complexity.
4. Resident and Staff Experience
Does the technology simplify daily operations or make them more difficult?
Technology should make processes such as move-ins, access management, maintenance, amenity reservations, package retrieval, temperature control, and communication easier.
A system that technically works but continually generates support requests, credential issues, or staff workarounds may not be creating meaningful value.
5. Financial Return
What measurable benefits can the technology generate?
Depending on the property and systems involved, benefits may include:
Technology fees or rent premiums
Utility savings
Reduced vacant-unit energy consumption
Fewer water-loss events
Reduced rekeying expenses
Improved maintenance productivity
Reduced administrative work
Better security and access control
Improved resident experience
Potential improvement in resident retention
These benefits need to be compared against the total cost of ownership, including hardware, installation, software, maintenance, connectivity, service, and future replacement.
6. Portfolio Scalability
Does the technology fit the owner’s broader operating model?
A system can work perfectly well at a single property but become difficult to manage across a portfolio.
Owners should consider whether:
Staff can be trained consistently
Reporting can be centralized
Credentials can be managed efficiently
The technology can be supported across multiple markets
The same deployment model can be repeated at future acquisitions
Standardization can create significant value, but that value needs to be weighed against the cost of replacing functional equipment prematurely.
7. Vendor and Technology Risk
Finally, owners should consider the long-term viability and flexibility of the technology ecosystem.
Important questions include:
Who owns the hardware?
Who owns the data?
Can the service provider or integrator be changed?
Is the system dependent on proprietary hardware?
Are replacement parts readily available?
Are software and cybersecurity updates continuing?
What happens if a manufacturer discontinues the product?
Can the system transfer to another owner when the property is sold?
After assessing these criteria, most acquisition strategies generally fall into one of four categories.
Scenario 1: Continue Operating the Existing Systems
Sometimes technology upgrades simply do not fit within the acquisition business plan.
Capital may be limited, other renovation priorities may provide a better immediate return, or the property’s existing systems may be functional enough that replacement cannot be justified.
In those circumstances, continuing to operate the existing systems may be the right answer.
This is especially true when:
The anticipated hold period is relatively short
The equipment remains functional
Technology is not creating major operational problems
Other capital improvements have a higher expected return
However, keeping the existing systems does not mean ignoring them.
The owner should still:
Inventory the existing hardware and software
Document warranties and service agreements
Identify subscription renewal dates
Determine who owns the equipment and data
Identify unsupported or obsolete systems
Eliminate unnecessary subscriptions
Track service calls and resident complaints
Create a phased replacement plan
The key is to establish clear triggers for future action.
Those triggers might include higher failure rates, software discontinuation, increasing support costs, major property renovations, or a change in the property’s operating strategy.
Scenario 2: Preserve the Existing Hardware but Create a More Unified Experience
This may be one of the most underutilized strategies in multifamily acquisitions.
In many properties, the technology itself is not bad. It simply has not been operated in a unified or scalable way.
Smart locks, access control, intercoms, amenity systems, and other technologies may all function well individually but operate independently from one another.
In this situation, the best strategy may be to preserve the hardware while improving the integrations and workflows around it.
Resident experience applications can be particularly useful in this scenario.
For example, an owner may acquire a property with relatively new Dormakaba locks that remain in good condition. Rather than replacing the locks, it may be possible to incorporate them into a broader resident experience platform that streamlines credential issuance, resident access, amenity access, move-ins, and move-outs.
Likewise, an existing common-area access control system may remain in place while receiving a new property-management-system integration or other workflow improvements.
This strategy can create meaningful value with substantially less capital than a complete hardware replacement.
The key questions are:
Can the existing systems actually be integrated?
Can residents use a consistent credential or mobile application?
Can staff manage the systems through fewer dashboards?
Are the integration and licensing costs reasonable?
Will the resulting system remain supportable over the anticipated hold period?
The biggest risk is assuming that integration is possible without confirming the specific hardware, firmware, software, and contractual requirements.
Scenario 3: Selectively Replace Portions of the Technology Stack
Selective replacement is probably the most common acquisition strategy.
A property may have some systems that perform well and others that are outdated, incompatible, unreliable, or poorly suited to the owner’s operating model.
Rather than replacing everything, the owner can focus capital on the systems that provide the greatest operational or financial benefit.
A reasonable prioritization might be:
Unsupported, unreliable, or obsolete systems
Systems creating significant resident or staff friction
Systems associated with safety, security, or water-loss risk
Systems with measurable revenue or operating savings
Systems preventing broader integrations
Systems that can be replaced efficiently during other renovation work
For example, an owner may choose to replace in-unit locks while retaining an existing Brivo common-area access control system.
This may reduce upfront capital while moving the property closer to the owner’s preferred technology standard.
However, the owner still needs to determine whether both systems can operate under a unified credential model and whether staff will need to manage multiple platforms.
Selective replacement can also be phased.
In-unit technology can often be installed during unit turns, while common-area systems can be replaced during renovations or as existing equipment reaches the end of its useful life.
The primary risk with selective replacement is accidentally creating a permanent patchwork of technologies.
Each decision should therefore move the property toward a defined future operating model.
Scenario 4: Replace and Standardize the Full Technology Stack
For larger owners, major repositionings, or organizations that have already established a preferred portfolio technology standard, full replacement may make the most sense.
This strategy can provide:
A consistent resident experience
Standardized staff training
Centralized reporting
Fewer vendor relationships
More predictable support
Consistent integrations
A repeatable model for future acquisitions
Owners pursuing this approach often already understand their approximate cost per unit, cost per access-controlled door, software cost, installation methodology, and support requirements.
Full replacement becomes particularly compelling when:
The property is already undergoing a major renovation
Existing equipment is obsolete
The current systems are highly fragmented
The anticipated hold period is long
Portfolio standardization creates substantial operating value
However, full replacement also creates risks.
These include:
Higher initial capital requirements
Replacing usable equipment before the end of its useful life
Installation disruption
Longer payback periods
Greater dependence on a particular technology ecosystem
For that reason, full standardization should be supported by a clear operational and financial case rather than simply a preference for consistency.
Matching the Strategy to the Business Plan
Technology decisions should also be considered within the timing of the overall acquisition plan.
During Due Diligence
The objective during due diligence should be to identify the existing systems, contracts, ownership rights, compatibility concerns, and likely future capital requirements.
The challenge is that acquisition teams often need to make these decisions quickly.
They may know that they want to replace locks, access control, thermostats, leak detection, cameras, or other systems, but they may not have enough time to conduct detailed engineering, complete site surveys, and obtain final vendor proposals before the acquisition model needs to be finalized.
This creates a budgeting gap.
We developed SmartScope to help address this problem.
SmartScope is designed to give owners a quick budgetary view of the cost to replace or upgrade technology at a property.
Using basic property characteristics—such as unit count, common-area access requirements, and the technology categories being evaluated—an owner can quickly establish the likely magnitude of a partial or complete technology upgrade.
It is not intended to replace a detailed site survey or final design. Its value is speed.
During acquisition underwriting, knowing whether a technology strategy is likely to require $100,000, $300,000, or $750,000 can be much more important than knowing the exact make and model of every device.
That preliminary number allows the acquisition team to incorporate technology into the capital plan early enough for it to influence the deal.
During the First 100 Days
Once the property has been acquired, the owner can address immediate operational problems, eliminate unnecessary subscriptions, standardize procedures, and implement lower-cost integrations.
The first 100 days can also provide valuable operating data that helps validate which systems truly need replacement.
During Unit Turns
In-unit locks, thermostats, leak sensors, and other devices can often be installed as units become vacant.
This reduces disruption and allows capital spending to be spread over time.
During a Major Repositioning
A more comprehensive technology replacement may be most efficient when coordinated with renovations, electrical work, common-area improvements, or other major building upgrades.
Ultimately, the technology plan should support the acquisition thesis.
A short-term hold with limited renovation may support a preservation or integration strategy. A longer-term value-add investment may justify a more substantial technology transformation.
Evaluating the Full Investment with SmartScope
Once the technology strategy begins to take shape, the next challenge is establishing a realistic capital requirement.
An owner may know conceptually that the property needs better locks, access control, thermostats, leak detection, cameras, or energy management.
The more difficult questions are:
How much will the desired technology package cost?
How much of the existing infrastructure can be reused?
What is the cost difference between selective replacement and full replacement?
Which improvements should happen immediately?
Which improvements can be phased?
How much recurring operating expense will the new systems add?
This is where SmartScope becomes particularly useful.
Consider a 250-unit acquisition.
The acquisition team might want to quickly estimate the cost of:
Replacing all unit locks
Replacing common-area access control
Adding smart thermostats
Adding leak detection
Expanding video surveillance
Adding resident experience integrations
Replacing the entire technology stack
Historically, developing even a preliminary budget might require site visits, individual equipment counts, discussions with multiple vendors, and preparation of several proposals.
That work is still important before deployment. It is often too slow, however, for acquisition underwriting.
SmartScope provides a way to develop an initial budget earlier in the process so different technology strategies can be incorporated into the business plan.
The technology budget should account for more than hardware.
Upfront Costs
A complete capital estimate may include:
Hardware
Installation
Wiring and infrastructure
Controllers and gateways
Project management
Training
Removal or disposal of existing equipment
Recurring Costs
Ongoing expenses may include:
Software subscriptions
Cellular or network connectivity
Monitoring
Maintenance
Service agreements
Replacement requirements
With those inputs, SmartScope can help an owner compare the approximate cost of the four strategies discussed earlier:
Preserve: Continue operating most of the existing systems.
Integrate: Retain usable hardware while improving software and workflows.
Selectively replace: Replace the systems creating the greatest operational or financial friction.
Standardize: Replace the existing technology with the owner’s preferred portfolio-wide solution.
That provides the acquisition team with an essential first answer:
What is the likely capital requirement associated with each strategy?
But cost is only one side of the equation.
The next question is whether the investment creates enough value to justify that capital.
Measuring the Impact with Impact Navigator
Once a preliminary scope and budget have been established, the analysis should move from cost to impact.
This is the role of Impact Navigator.
Impact Navigator is designed to evaluate the potential financial and operational impact of a smart building technology investment.
Smart technology can create value in several ways. Not every benefit appears as a direct technology fee or rent premium.
Depending on the technology being considered, potential benefits might include:
Technology fees or rent premiums
Utility savings
Reduced vacant-unit energy usage
Reduced water-loss exposure
Reduced lock and rekeying expenses
Improved maintenance productivity
Reduced administrative work
More efficient resident move-ins and move-outs
Better access management
Improved security
Potential improvements in resident satisfaction and retention
This is important because individual technologies often produce value in very different ways.
A smart thermostat program, for example, may not create meaningful direct resident revenue, but it may produce attractive returns by reducing vacant-unit energy usage.
Leak detection may be difficult to evaluate based on annual recurring revenue, but preventing even one substantial water-loss event can materially affect the economics.
Smart access may generate a technology fee while also reducing physical-key management, rekeying expense, and staff time.
Looking at any one of those benefits in isolation can understate the impact.
Impact Navigator is intended to bring those value drivers together so owners can evaluate metrics such as:
Initial capital investment
Recurring operating expense
Incremental annual revenue
Annual operating savings
Payback period
Multi-year cash flow
Potential NOI improvement
The objective is to move beyond the question, “Can we charge residents $30 per month for smart-home technology?” and instead ask,
“What is the total financial and operational impact this investment could have on the property?”
From Scope to Impact
Used together, SmartScope and Impact Navigator create a logical decision path:
What technology exists today?
What should we keep, integrate, or replace?
What will the proposed strategy cost? SmartScope
What financial and operational impact could it generate? Impact Navigator
Does that impact justify the investment?
This changes the technology discussion from “Which product do we prefer?” to “Which technology strategy creates the greatest value for this particular investment?”
That is a very different conversation—and ultimately the one acquisition teams should be having.
A Simplified Acquisition Example
Consider a 250-unit acquisition with relatively new in-unit locks, an older common-area access control system, limited leak detection, and no centralized resident technology platform. The owner could evaluate three different approaches.
Option A: Preserve Most Existing Technology
This approach requires relatively little upfront capital but maintains much of the existing fragmented operating environment.
SmartScope can establish the limited capital required to maintain or modestly improve the existing systems.
Impact Navigator can then help determine whether the lower investment produces an acceptable outcome—or whether the property is leaving meaningful revenue and operating savings unrealized.
Option B: Retain Unit Locks but Upgrade Common Access and Integrations
This option preserves the investment in relatively new unit locks while replacing the older common-area access system and improving integrations.
SmartScope can quickly estimate the incremental capital required for access control, integrations, installation, and other selected improvements.
Impact Navigator can then evaluate the associated revenue opportunities, operating efficiencies, access-management savings, and other impacts.
This strategy may produce most of the operational benefit of a full replacement while requiring substantially less capital.
Option C: Replace and Standardize the Full Technology Stack
The third option is to replace the full technology environment.
SmartScope can establish the approximate investment required for locks, thermostats, leak detection, access control, cameras, infrastructure, installation, and software.
Impact Navigator can then evaluate whether the incremental benefits from full standardization justify the additional investment.
The analysis might show that Option C creates the greatest absolute financial benefit but has a longer payback period.
Alternatively, Option B might generate 80% or 90% of the available operational impact with substantially less capital.
That is exactly the type of tradeoff an acquisition team should understand before committing to an approach.
Without a structured way to evaluate both cost and impact, owners can easily default to one of two extremes: do nothing or replace everything.
Neither answer is necessarily correct.
The better approach is to quantify the alternatives and select the strategy that best supports the property’s business plan.
Conclusion
Smart technology should be approached as an operating and capital-allocation decision, not simply a product-selection exercise.
The goal is not to deploy the most technology. The goal is to select the right technology strategy for the property, the residents, the operating team, and the investment plan.
For some acquisitions, the right decision will be to preserve the existing technology.
For others, the greatest value may come from improving integrations, selectively replacing underperforming systems, or standardizing the entire property on a preferred technology platform.
The important step is to evaluate those alternatives early—ideally during due diligence—while there is still time to incorporate the anticipated cost and financial impact into the acquisition model.
SmartScope and Impact Navigator are intended to make that process faster and more quantitative.
SmartScope helps answer: What is the technology strategy likely to cost?
Impact Navigator helps answer: What financial and operational impact could that investment create?
Together, they give acquisition teams a way to move from an incomplete understanding of the existing technology to a defined strategy, a realistic capital requirement, and an analysis tied directly to the property’s pro forma and NOI objectives.
The result should not be a generic technology package.
It should be a property-specific strategy that preserves useful investments, addresses operational pain points, improves the resident experience, and directs capital toward the opportunities with the strongest potential return.
