Short-term rental DSCR in Los Angeles and the Inland Empire

Two ways a lender can count the income

The simpler method values the property as if it were rented long term. The appraiser completes a rent schedule using comparable long-term leases, the lender applies that figure to the ratio, and the nightly performance of the property is irrelevant to the approval. It is conservative, it is fast, and it is the fallback in markets where nightly income is volatile or the rules are unsettled.

The documented-income method looks at the actual business. The lender reviews platform statements, a bank statement history, and often the Schedule E from your tax return, then applies its own vacancy and expense assumptions. This method can produce a much higher qualifying income — and it asks for a much deeper file, with seasonality, management costs, cleaning, supplies and platform fees all on the table.

Local rules decide whether the income exists

There is no single short-term rental rule across Southern California. The City of Los Angeles limits short-term rentals to the host’s primary residence, which makes a whole-home investor STR effectively unavailable inside the city. Other LA County cities set their own rules.

In the Inland Empire, unincorporated San Bernardino County requires a short-term rental permit for stays of thirty days or less, and the Coachella Valley cities each run their own permitting programs. For a lender, the question is not whether the property would make a good short-term rental — it is whether the use is legal, documented and durable at that specific address.

• Current short-term rental permit or license for the specific address
• Local caps on nights, guest counts and permit transfers
• Transient occupancy tax registration and payment history
• HOA governing documents, including rental-duration restrictions
• Whether the property sits in an incorporated city or an unincorporated area

The appraisal is where these files are won

A short-term rental appraisal is not a standard form filled out the same way. The appraiser has to understand the local market, choose comparables that actually trade as short-term rentals, and support a rent conclusion the underwriter will accept. In Big Bear, the desert and other resort submarkets, those comparables can be thin.

Providing the appraiser with organized documentation — the permit, a year of booking history, a revenue summary and nearby comparable properties — removes an avoidable reason for a low rent figure: an appraiser with nothing to work with.

Seasonality, vacancy and the expense line

A short-term rental that grosses well in festival season and sits empty in summer heat is a different asset from one that runs at steady occupancy. Lenders know this, and the stronger programs apply a vacancy factor rather than taking annual gross bookings at face value.

Management fees, cleaning, utilities, supplies and platform commissions are real costs that reduce the income available to pay a mortgage. The ratio uses the net figure, not the gross one — and this is where investors most often overestimate their qualifying income.

Furnishing costs are usually not part of the ratio. They are part of your cash to close.
