Price-per-door screening is useful—but it can hide the costs that determine whether an apartment property is viable to own.
Price per unit is an easy number to compare across listings, and that is why it can become more persuasive than it deserves. A low asking price may leave room to fix a property, but it can also be the market’s way of pricing vacancy, physical problems, thin tenant demand, or an operating burden that does not show up in the headline. The useful question is not only what each apartment costs to buy, but what capital and operating cash it will take to make the property perform.
A live listing shows why the distinction matters
The public LoopNet listing for 423 Briarwood Avenue in Dayton markets a ten-unit apartment building at $585,000, or $58,500 per unit, with an advertised 8.09% cap rate. The listing says the property is about 50% occupied and explains that units were vacated during a sewer-line replacement it describes as complete. That is a plausible reason for temporary vacancy, but a reason is not the same as collected rent or a completed lease-up plan.
The financial summary is labeled “Pro Forma - 2026” and projects $90,000 in gross rent, $9,000 in vacancy loss, and $47,346 in net operating income. The same listing shows ten one-bedroom apartments at $750 per month. At that rent, ten units produce $90,000 in annual gross rent if all are occupied for the full year; the pro forma’s $9,000 vacancy deduction is 10% of that amount. Yet the property facts and description report roughly 50% occupancy. There may be timing, definitions, or other assumptions behind the difference, but a buyer should understand it before treating the advertised yield as a picture of current operations.
The cash required is more than the purchase price
For a property like this, the total cash required starts with the price and also includes closing costs, immediate repairs, unit turns, leasing costs, and carrying costs during lease-up. The owner also needs reserves for the work and expenses that follow stabilization. The operating budget needs a separate look at taxes, insurance, water and sewer, common utilities, routine maintenance, management, and replacements over time. These costs do not all belong in the cap-rate calculation, but they all affect whether the investment can meet its obligations and fund the next round of work.
That is where “cheap per door” can turn into expensive ownership. If the sewer work is complete, that may remove one important risk, but we still need documentation of the scope and quality of the work. Vacant units need a realistic schedule and cost to return to service, while the rent assumptions need support from signed leases or comparable rentals. The property can still be attractive, but the case should reflect the costs and time between today’s condition and stabilized operations.
Replacement cost is useful context, not a cash-flow plan
A large gap between the cost of existing apartments and the cost of new construction can matter because it may be difficult for new supply to compete at the same rent. It does not guarantee that a particular older property is well located, well maintained, or affordable for its residents. If household incomes do not support the rents needed to justify improvements, or if systems and layouts make those improvements unusually expensive, the building can remain cheap for good reasons.
At DV, we use price per unit to decide which properties deserve more attention, not to replace the rest of the underwriting. For Briarwood, a next step would be to reconcile the current rent roll and collections with the pro forma, inspect and document the sewer work, price each remaining unit turn, and model a slower lease-up with continuing expenses. Then we would ask whether the verified income can support conservative debt service and a realistic reserve—not just whether the purchase price looks low beside a new-build estimate.
The contrarian point is straightforward: a low entry price is valuable only when the property’s income and condition give the owner room to carry the work ahead. Without that, a discount can simply be the first payment on a more expensive problem.
