Rent vs Buy Calculator for California

It depends on how long you plan to stay. Below 5 years, renting is almost always cheaper because buying transaction costs (closing costs, agent fees, moving) take 3 to 5 years to amortize. Above 7 years, buying typically wins because equity builds and rent inflation compounds against you. The break-even in California usually lands between year 5 and year 7 at current rates.

The 5% rule says buying is worthwhile when annual ownership costs (mortgage interest, property tax, maintenance, insurance, HOA) stay below 5% of the home value. In California with 0.73% property tax and 7.50% mortgage rate, the total ownership cost runs around 5.5% to 6% annually — slightly above the threshold, meaning buying requires longer holding periods to break even.

On a median $809,000 California home with 20% down, the equivalent rent is roughly $4,045 per month. That is the rent above which buying becomes financially favorable, assuming a 7-year stay. Below that rent, the money saved by renting and investing the difference outperforms homeownership. Above it, buying builds equity faster than renting preserves capital.

Minimum down payments in California vary by loan type: 3% for conventional, 3.5% for FHA, 0% for VA and USDA. A 20% down payment on the median California home runs $161,800 and avoids PMI. Lower down payments are viable but add $100 to $300+ per month in PMI or MIP and typically increase the interest rate by 0.25% to 0.5%.

Closing costs in California run 2% to 5% of the purchase price — about $4,000 to $10,000 on a median home. Prepaid escrow (property taxes and insurance) adds another $2,000 to $4,000. Emergency reserve of 3 to 6 months expenses is strongly recommended. Total cash-to-close plus reserve usually runs down payment plus 6% to 10% of purchase price.

Yes — that is the key variable. The rent-vs-buy math only favors renting when the difference between rent and ownership cost is invested at market returns. If you rent but spend the difference on lifestyle, buying wins by default. If you invest the difference at 7% annual return in a diversified portfolio, renting often wins for short holding periods and ties or loses for long ones.
