The BRRRR method works wherever rent-to-value ratios are high, and struggles wherever they are not. California pairs a typical home value near $762,000 with median rents around $2,104 per month and an effective property tax rate of 0.71% — three numbers that together decide whether a buy-rehab-rent-refinance deal can return capital. Below, the tool is preloaded with a California deal built from those figures, and the worked example shows exactly how each output is calculated.

California-specific costs and rules
Property taxes in California
Proposition 13 caps assessed-value growth at 2% per year and reassesses the property at market value on transfer — a long-held rental often pays a fraction of what a new owner pays. On the example ARV of $685,000, that rate works out to $4,860 per year — $405 every month that rent must cover before anything else reaches you.
Insurance and physical risk in California
Budget roughly $1,300 per year for a landlord policy. Wildfire and earthquake exposure shape Western insurance: standard policies exclude earthquake damage, and homes in high-fire zones increasingly face non-renewals or FAIR Plan backstop coverage. Get an actual quote before you write an offer — premiums on the same house can swing by thousands.
Landlord rules in California
AB 1482 caps annual rent increases at 5% plus local CPI (or 10%, whichever is lower) for most buildings over 15 years old; Los Angeles, San Francisco, and Oakland add stricter local rules.
How to run your own California BRRRR analysis
- The tool above loads with a California example built on statewide data. Replace the purchase price with your actual offer — the rehab budget, closing costs, and holding costs will not update for you.
- Set the ARV from three comparable sold renovations within a mile and built in the last 12 months, not from the median value used here.
- Swap the rent for a comps-based number: an arm's-length three-bedroom single-family rental within a mile, rented in the last 90 days.
- Re-run property taxes from the county assessor's bill rather than the statewide 0.71% average — local millage inside California varies far more than the state figure suggests.
- Watch two cards: cash left in the deal must stay positive for the refinance to return capital, and cash flow must stay positive for the deal to hold without subsidizing it.
Methodology
All-in cost is purchase price + rehab + purchase closing costs + (holding cost per month × holding months). Refinance proceeds are ARV × 75% LTV, minus2.5% closing. Cash left in the deal is all-in cost minus net proceeds; cash flow is rent minus operating expenses (taxes, insurance, vacancy, maintenance, management) minus the fixed principal-and-interest payment on the refinance.
The defaults here are deliberately derived from public statewide data, so they illustrate the California market rather than any specific property. The formulas, worked examples, and caveats are explained in full in the national BRRRR calculator guide, and the interactive tool above applies exactly the same math to whatever numbers you enter.

California FAQ
- Is BRRRR investing realistic in California at today's interest rates?
- It depends on the local rent-to-value ratio. At the defaults above — a $685,000 ARV rented for $3,150 per month — the deal runs $1,463 of negative cash flow, because carrying a 75% LTV refinance at 6.875% needs roughly $5,050 of rent (8.8% gross) while the example delivers 5.5%. California deals pencil when you buy deeper than the 65%-of-ARV default or find rent above the statewide median.
- How much cash do I need for a BRRRR deal in California?
- On the example above, about $71,544 stays in the deal after the refinance — the down payment, rehab, closing costs, and six months of holding costs minus what the refinance returns. Lenders typically require reserves of six months of payments on top, and BRRRR investors also fund cost overruns: the example budgets a $95,000 rehab, and real rehabs routinely overrun 10–20%.
- Do California property taxes break BRRRR cash flow?
- At 0.71%, California's effective rate produces $4,860 per year on the example ARV — $405 monthly, roughly 13% of the assumed rent. Proposition 13 caps assessed-value growth at 2% per year and reassesses the property at market value on transfer — a long-held rental often pays a fraction of what a new owner pays. Always re-run the number from the assessor's bill for the specific parcel.
- What rent should I assume for a California rental?
- The defaults use $3,150 — about 1.5× the statewide median of $2,104, reflecting that BRRRR candidates are typically three-bedroom single-family homes rather than the apartments that pull the overall median down. Replace it with a comps-based rent before trusting any output: an arm's-length rental of a similar house within a mile, rented in the last 90 days.
