San Bernardino and Rialto usually win on rent-to-price. Fontana and Ontario carry costs people forget. Here is how I underwrite a rental before making an offer.
Rent-to-price is where you start, not where you stop
A quick screen tells you whether a property is worth a full underwrite. Across the Inland Empire, San Bernardino and Rialto generally produce the best gross rent relative to price. Fontana and Ontario have newer inventory and strong logistics employment, but the carrying costs are higher.
The expenses most spreadsheets skip
Special assessments
Mello-Roos districts in newer neighborhoods can add hundreds a month. Always pull the actual tax bill for the exact address rather than assuming the base rate.
HOA dues
Common in newer tracts. They are not optional and they rarely go down.
Vacancy and maintenance
Budget for both even if the current tenant has been there for years. A single turnover plus a water heater erases a thin margin.
What a real cap rate looks like here
Once taxes, insurance, HOA, assessments, vacancy and maintenance are in, most solid Inland Empire rentals underwrite in the low-to-mid single digits. That is not a bad deal — it is an honest one. If someone shows you double digits in this market, ask which expenses they left out.
Appreciation versus cash flow
Redlands and Rancho Cucamonga behave like stability plays: stronger tenant pools, steadier value, thinner monthly returns. San Bernardino and Rialto trade some of that stability for cash flow. Neither is better — they answer different goals.
How I underwrite before writing an offer
- Pull the actual tax bill and any assessment detail.
- Verify comparable rents, not asking rents.
- Model vacancy, maintenance and management even if you self-manage.
- Stress test the payment against a rent 8% lower than expected.
If you want a specific address run through this, send it over and I will underwrite it with you.
Common questions
What is a realistic cap rate for an Inland Empire rental?
Low-to-mid single digits after taxes, insurance, HOA, Mello-Roos, vacancy and maintenance. Numbers well above that usually come from skipped expenses or optimistic rents.
Which Inland Empire cities cash flow best?
San Bernardino and Rialto typically deliver the strongest rent-to-price ratios. Redlands and Rancho Cucamonga are appreciation and stability markets rather than cash flow markets.
