Short-Term Rentals: What Owners Should Check Before Buying

A short-term rental purchase starts with the address, not a projected nightly rate. First find out whether the property can be rented that way. Then price the work and expense of serving guests between bookings.

Check the address before the revenue forecast

Identify the city or unincorporated county, the property's zoning and approved use, the permit path, and any HOA or deed restrictions. A listing platform's revenue estimate cannot tell you whether that address is eligible.

The local differences are substantial. San Bernardino County's program describes permits for eligible properties in its Mountain and Desert regions. Los Angeles City Planning's home-sharing resources describe a program tied to a host's primary residence. Neither example establishes eligibility for a particular property. Check current requirements with the responsible city or county before making a purchase or conversion decision.

Pay close attention to the structure. San Bernardino County lists eligible and ineligible property types and gives separate guidance for accessory dwelling units. Do not assume that an apartment, condominium, or ADU has the same permit path as a detached house.

Price the coverage between guests

A reservation also creates cleaning, supplies, inspections, repairs, guest questions, and complaint response. Decide who answers the phone after hours, who can get to the property, and who can approve an urgent repair. Put those assignments in writing before you compare management proposals.

For example, San Bernardino County Code §84.28.070(g) calls for a 24-hour phone contact, the ability to make contact by phone within 30 minutes, and physical presence within one hour to respond to complaints. Those are published county conditions for its short-term rentals, not a statewide response rule. The code publisher cautions that its electronic text may lag amendments, so confirm the current official rule and permit conditions for the address.

Build a property-level worksheet

Estimate booked nights by season. From projected revenue, subtract platform fees, cleaning, utilities, supplies, insurance, applicable taxes and permits, maintenance, management, and replacement of furniture and equipment. Include the owner's or local representative's time for exceptions.

Run a downside case with lower occupancy and higher turnover costs. Compare the resulting net income with other lawful uses of the property using the same financing and repair assumptions. If the purchase works only when each month performs like peak season, the margin for error is thin.

Know what a manager will handle

• Who handles guest questions and complaints after hours, and how quickly?
• Who schedules cleaning, checks the property, and documents damage or repairs?
• What costs fall outside the base fee, and which decisions need owner approval?

Review the proposed agreement and a sample owner report. A manager can reduce daily work when the coverage, authority, and fees are explicit. Coastline's published services focus on commercial and multifamily property management. That scope should not be read as an offer of short-term-rental management.

Before you make an offer, put three answers in the file: the address-specific permit path, the person responsible for each operating task, and the downside case for net income. A headline nightly rate is useful only after those questions are settled.
