Apartment Building and Multifamily Property Valuation
29 valuation methods · 43 industries · Results in under 10 minutes
In short
An apartment building is valued as property: net operating income, rebuilt from the operating statement, divided by a cap rate from your own figure, comparable sales or a market survey. The owner's equity is that value less the debt on the building.
Who this is for
Owners and buyers of apartment buildings who have a trailing twelve-month operating statement and a rent roll, and want the property priced the way a broker and a lender will price it rather than on a rule of thumb per door.
How is an apartment building valued?
VA values an apartment building as property, not as a company: net operating income divided by a cap rate. The income is rebuilt from your trailing twelve-month operating statement: rent at market, less the gap to the rents in place, vacancy, concessions and bad debt, plus other income, less each operating expense line and replacement reserves. Where the statement leaves a line out, such as vacancy, reserves or every expense, VA fills it with a stated assumption and says so. The cap rate is your own, the median of comparable sales you enter, or a published survey for your market, and the report always names its source. Debt on the property, less cash, is deducted to reach the owner's equity. A discounted cash flow, comparable companies and precedent transactions carry no weight for a building. This tool is informational only. Output is driven by your inputs and does not constitute a formal appraisal or certified valuation.
What drives the value of an apartment building?
- Net operating income rebuilt from the operating statement, not the figure printed on the package
- The cap rate for your submarket, which varies far more between cities than most owners expect
- Loss to lease, the gap between the rents in place and what the units would let for today
- Economic vacancy, which is empty units plus concessions and bad debt
- The operating expense ratio, with real estate taxes read at what a sale would trigger rather than the current bill
- Replacement reserves, because income struck before reserves is not the number a lender underwrites
What lowers the value of an apartment building?
- Rents below market that take years to catch up
- Real estate taxes that rise when a sale triggers a reassessment
- Deferred maintenance the reserves do not cover
- A cap rate taken from a market that has since moved
How much is an apartment building worth? A worked example
An apartment building, by cap rate
Take a 100-unit apartment building whose rents would total $2.04 M a year at market, $120 K more than the leases in place bring in. After that gap, vacancy, concessions and bad debt, and with $60 K of parking and other income, effective gross income is $1.86 M. Operating expenses, including a 3% management fee, come to $681 K, or 36.5% of that income, and replacement reserves take $30 K, which leaves $1.15 M of net operating income. Suppose comparable sales put the cap rate at 5.6%. VA's apartment model divides the income by it, which puts the building at about $20.6 M, or $206 K a unit, within a range of $18.9 M at 6.1% to $22.6 M at 5.1%. After a $9 M loan less $300 K of cash, the owner's equity is about $11.9 M. At 6.6%, one point higher, the same income is worth about $17.5 M. For an apartment building this is the whole report: a discounted cash flow, comparable companies and precedent transactions carry no weight, because none of them means anything for a building.

Which numbers matter most?
Net operating income
Rebuilt from the operating statement, after vacancy, concessions, bad debt, every expense line and replacement reserves. Not taken from the summary page.
Cap rate
Net operating income divided by value. VA takes your own rate, the median of comparable sales, or a published survey for your market, and says which. A small change moves the price a long way, as the worked example shows.
Loss to lease
Rent at market less the rent in place. It sizes the upside a buyer can capture as leases turn over, and it is counted as upside only when you supply a market rent.
Operating expense ratio
Total operating expenses over effective gross income. VA flags a ratio well below or well above what stabilized apartment buildings run at, since either usually means a missing or misfiled line.
Value per unit
The value divided by the number of apartments, the figure brokers and buyers compare across buildings. With comparable sales entered, their median price per unit serves as a cross-check.
What do you need to value an apartment building?
- Profit and loss statements and balance sheets, ideally for the last three years
- Figures for the current year to date
- A list of add-backs: the owner's pay and perks, and any one-off costs
- Loan and lease balances
- A trailing twelve-month operating statement with every expense line
- The current rent roll with lease dates and rents in place
- Recent sales of comparable buildings, with price and net operating income
Example scenarios
Rents below market
When the rents in place sit below market, the gap is taken out of income, so the value rests on the rents tenants actually pay. What the building would be worth at market rents is shown only when you supply a market rent yourself.
A statement with no expenses
A statement that shows rent but no expenses would make the building look far more valuable than it is. VA assumes an expense ratio at the middle of the usual range for stabilized apartments, says so, and asks you to replace it with the real lines.

Frequently asked questions
Why do you not use the NOI on the broker package?
Because a printed net operating income is often struck before replacement reserves, before a management fee, or on pro forma rents nobody is paying yet. VA rebuilds it from the line items and keeps the printed figure only as a cross-check.
What cap rate applies to my building?
The one for your submarket, not a national average. VA uses your own rate, the median of comparable sales you enter, or a published survey for your market, and always says which. The spread between markets is wide enough to move a price by millions.
Why are replacement reserves deducted?
Because a lender underwrites income after reserves for roofs, boilers and unit turns. Income struck before reserves overstates what the building earns year after year.
Do you value rent upside?
Only when you supply a market rent independently. Inferring a market rent as the rent in place times a factor would create upside out of nothing, so VA does not guess.
How is the owner's equity worked out?
The value of the building less the debt on it, net of cash. When the debt exceeds the value there is no equity left, and VA says so.
Can I value an office, retail or industrial property?
Not yet. Apartment buildings are the property type modelled, because it is the one whose cap rate can be sourced properly. The tool declines other types rather than produce a number it cannot stand behind.
Is this a certified appraisal?
No. A lender or a purchase contract will require a licensed real estate appraisal. This is an informational estimate to help you price, underwrite and negotiate.
Terms used on this page
- Net operating income (NOI)
- A property's rent and other income, less vacancy and every operating expense, before debt service, depreciation and income tax. It is the income a cap rate is applied to.
- Capitalization yield
- The yearly earnings a buyer requires as a share of the price. The value is the earnings divided by the yield, so a lower yield means a higher value.
- Enterprise value
- The value of the business itself, before debt is subtracted and cash added. The owner's proceeds come from what is left.
