  • Comparable apartment building sales in your area

How ACI Determines Your Apartment Building's Appraisal

A property tax assessment or an online estimator won’t tell you what your building is actually worth to a buyer today and neither will replacement cost. Apartment building Market appraisal is determined by what similar multifamily properties are actually trading for right now, adjusted for your building’s specific unit mix, condition, location, and income.

When ACI values your apartment building, we look at three things together: recent comparable sales of similar multifamily properties in your submarket, the cap rate buyers are currently underwriting to for a property like yours, and how today’s financing environment affects what a buyer can realistically pay. We also review your gross rent multiplier (GRM) as a secondary check, and account for any upside between your in-place rents and current market rents. This is the same analysis we use when we represent buyers and sellers directly not a generic formula, but a read on the actual San Diego multifamily market as it stands today.

What Affects the Value of a San Diego Multifamily or Rental Property

Several factors move the needle on what a San Diego apartment building or rental property is worth beyond just square footage and unit count: 

Location and submarket. San Diego’s multifamily market isn’t one market — coastal, urban-core, and inland submarkets each carry different buyer demand and cap rate expectations. 

Unit Mix and Rent Upside. Buildings with rents meaningfully below market typically command a premium, since buyers are underwriting the path to market rent, not just current income. 

Rent Control and Local Ordinance Exposure. State and local rent control rules affect how buyers evaluate your income growth potential — this is one of the most common questions we get from owners. 

Deferred Maintenance and Building Systems. Aging electrical panels, roofing, plumbing, and other capital items are typically priced into an offer, sometimes more heavily than owners expect. 

Current Lending Conditions. Interest rates directly affect what buyers can pay and still hit their return targets, which is why a valuation done today can look different from one done even six months ago. 

If you’re not sure how these factors apply to your specific property, that’s exactly what a valuation from ACI is for.
