San Diego Multifamily & Apartment Building Blog

2025 was a pricing-reset year for San Diego multifamily, marked by disciplined buyers and selective liquidity rather than distress.
Small-unit demand remained strong due to financing access and optionality, while 5+ unit transactions centered on income durability, positioning owners who exchanged into higher-quality assets best for 2026.

San Diego is in the middle of a significant multifamily supply wave — and it’s beginning to show up in rents, concessions, and vacancy. Learn where this is concentrated and the affects!

With 209 five-plus unit buildings currently sitting on the market and an average 159 days on market, many San Diego sellers are hesitant to list heading into 2026. But capital is still actively seeking well-positioned assets — and with disciplined pricing and a consistent, multi-channel marketing strategy, properties are still trading well below the county average days on market.

Under-market rents don’t just reduce monthly income — they directly compress your valuation, increase buyer leverage, and shift upside away from you and into the buyer’s hands.

When a multifamily property enters probate in San Diego, valuation becomes the foundation of every decision that follows.

San Diego multifamily lending has changed in 2026. Lenders are prioritizing in-place cash flow, tighter DSCR, and conservative assumptions — meaning refinance proceeds may be lower than expected. Understanding how your property underwrites today is critical before refinancing or selling.

In probate and trust sales, uncertainty creates risk. When beneficiaries do not receive consistent communication, assumptions fill the gap. Assumptions lead to conflict. Don’t let this happen to you.

Selling an apartment building through probate is not the same as selling a single family residence. Income property is valued based on performance, risk, and financeability. When trustees approach a multifamily sale emotionally or without specialized guidance, value is often left on the table.

Financing an apartment building is very different from financing a duplex or fourplex. Once a property reaches five units or more, lenders treat it as a commercial asset rather than residential real estate. This shift changes how the property is evaluated, how loans are structured, and what investors must demonstrate in order to secure financing.

The 2–4 unit multifamily market occupies a unique space in San Diego real estate. Duplexes, triplexes, and fourplexes behave very differently from larger apartment buildings because they qualify for residential financing rather than commercial underwriting.

Improvement 1031 exchanges allow investors to defer taxes while reinvesting into multifamily properties that require renovations or upgrades. For San Diego investors pursuing value-add apartment buildings, this strategy can unlock long-term upside when structured correctly.

Short-term rentals are no longer a side category in San Diego’s lodging market. According to recent CoStar Analytics data, STR demand has grown from roughly 10% of hotel demand before 2020 to nearly 20% today. In San Diego, STR inventory is now equivalent to approximately one-quarter of total hotel room supply, making STRs a measurable part of the same demand pool as traditional hotels.

San Diego’s multifamily market continues to show a clear divide between smaller 2–4 unit properties and larger 5+ assets. While transaction volume remains strong in the 2–4 space, pricing is still adjusting to align with today’s lending environment, with most deals trading slightly below list. Properties supported by real in-place income and clean operations are consistently outperforming those reliant on future upside assumptions.
