What to Know About Short-Term Rental Financing in San Diego

San Diego is one of the strongest short-term rental markets in California: year-round tourism, a dense coastal supply constraint, and consistent occupancy keep nightly rates high. That same market strength shapes how lenders look at deals here. Properties that clear a 65% or higher occupancy rate attract the most competitive terms; anything below that and underwriters start discounting projected income.

The loan types San Diego STR hosts actually use

DSCR loans are the workhorse for most acquisition and refinance deals. Instead of verifying your personal income, the lender sizes the loan to the property's projected rent — usually benchmarked against an AirDNA or Rabbu market report. The property needs to cover at least 1.25x its monthly debt service to get approved at standard pricing. Rates on DSCR loans for short-term rentals in 2026 run roughly 7.5–9.5% APR, and down payments land at 20–25%. San Diego purchase prices being what they are, 20% on a coastal property often means $200,000 or more out of pocket, so confirm your liquidity before you lock a rate.

Cash-out refinance makes sense if you already own a San Diego property with equity. You pull cash at refi, redeploy it into a second unit, a renovation, or reserves. DSCR cash-out underwriting follows the same income logic — projected STR income services the new debt. Loan-to-value caps on cash-out refis for investment properties typically sit at 70–75%, so model your equity position carefully.

Non-QM bank-statement mortgages serve hosts whose tax returns understate income after depreciation and write-offs. Lenders review 12 months of bank statements, average the deposits, and use that figure for qualification. The trade-off: rates run 1–2 percentage points above conventional, and lenders usually require 6–12 months of PITI in liquid reserves at closing.

Bridge loans fit the gap between acquisition and stabilization — useful when you're buying a property that isn't yet operating as an STR and can't show rental history. Terms are short (typically 12–24 months), rates are higher, and the exit is a permanent DSCR or conventional refi once the property is seasoned.

Fix-and-flip or renovation loans apply when the asset needs work before it can generate STR income. These are draw-based construction facilities; the permanent takeout is usually a DSCR loan once the renovation is complete and the unit is listed.

What trips people up in this market

• HOA and city restrictions. San Diego has a patchwork of STR permit requirements by neighborhood. Some HOAs prohibit short-term rentals outright, which voids the STR income assumption entirely. Lenders and appraisers are aware of this — confirm permit eligibility before underwriting.
• Appraisal method mismatch. A standard comparable-sales appraisal won't capture STR income potential. Push for an income-approach or hybrid appraisal from an appraiser with STR market experience.
• Portfolio concentration. If you're financing multiple San Diego Airbnb properties, conventional lenders cap out at 10 financed properties. Portfolio lenders and non-QM lenders go higher, but terms tighten as concentration increases. Hosts running three or more units in the same ZIP code should model their aggregate debt load against realistic seasonal income swings.
• Credit score benchmarks. A 640+ FICO gets you in the door at most DSCR lenders; 700+ earns meaningfully better pricing. Borrowers in the 640–679 range typically pay 2–4 percentage points more than well-qualified counterparts.

Hosts pursuing short-term rental financing in comparable high-demand California markets like Anaheim run into the same HOA and permit friction — the underwriting approach is nearly identical. If you're also weighing an expansion outside California, Airbnb investment property financing in Arlington, TX shows how DSCR qualifying works in a market with lower price points and different occupancy dynamics.

For hosts who own the property but want to avoid a full mortgage refinance, an Airbnb business line of credit through unsecured business credit can fund furnishings, maintenance reserves, or a small second unit without touching your mortgage stack.
