The Real Break-Even on Buying a Home (It's Probably Later Than You Think)

Most people who run a rent-versus-buy comparison start with the monthly payment. If buying costs less per month than renting, or close to it, they conclude that buying is the right move. That comparison misses several large costs that only become visible when you start counting the total money in and out over time.

The real break-even on buying a home, the point at which you have financially done better owning than renting, is often 6 to 10 years in high-price California markets. Here is how to think through the math honestly.

Why the Monthly Payment Is the Wrong Starting Point

The monthly mortgage payment includes principal and interest. Over time, the principal portion builds equity, which feels like saving. But in the early years of a 30-year mortgage, the payment is almost entirely interest. In year one on an $800,000 loan at 6.75%, you pay approximately $53,700 in interest and build only about $4,400 in principal equity through amortization.

Additionally, the monthly cost of ownership is not just the mortgage payment. Property taxes, homeowners insurance, HOA fees, and maintenance all add to the monthly obligation. On a $1.1 million home in Orange County, the total monthly cost of ownership commonly runs $7,500 to $9,500, well above a comparable rental in the same neighborhood.

The Cost You Pay to Get In

Buyers pay closing costs to enter the transaction. In California, a buyer's total closing costs including prepaids typically run 2% to 4% of the purchase price. On a $1 million purchase, that is $20,000 to $40,000 paid at closing that you will not recover until the home appreciates enough to cover it.

From day one, a buyer is in a hole relative to a renter who kept that capital liquid. The home needs to appreciate, or the monthly cost of renting needs to exceed the monthly cost of ownership by enough to recoup that gap. In high-price California markets, this takes time.

The Cost You Pay to Get Out

Selling a home is expensive. In California, sellers typically pay 4% to 6% of the sale price in transaction costs, including agent commissions, transfer taxes, and miscellaneous closing costs. On a $1.2 million exit, that is $48,000 to $72,000 off the top of your gross proceeds.

The break-even calculation must account for both the cost of entry and the cost of exit. A home bought for $1 million with $30,000 in buyer closing costs and sold for $1.15 million with $60,000 in selling costs nets $1.09 million on a $1 million investment, a nominal gain of $90,000. Over five years, that represents less than 2% annualized return on the purchase price, before accounting for the interest paid, the property taxes, and the maintenance.

The Hidden Variable: Opportunity Cost

The down payment is typically 10% to 20% of the purchase price. On a $1 million home, that is $100,000 to $200,000 in capital that is no longer available for other uses.

A renter who keeps that $150,000 in a diversified investment portfolio earning a long-run average of 7% to 8% annually has, over 10 years, grown that capital to roughly $295,000 to $323,000. A buyer who put that same $150,000 into a down payment has converted it into home equity, which earns the rate of local home price appreciation, not the stock market rate.

In high-appreciation markets like Silicon Valley, this comparison has historically favored buying over long hold periods. In more moderate-appreciation markets, or over shorter time horizons, the invested down payment often produces comparable or superior returns to the equity built through ownership. The outcome is market-specific and time-horizon-specific.

Where the Break-Even Actually Falls

A complete break-even calculation accounts for:

• Total closing costs paid to enter

• Total transaction costs paid to exit

• Net interest paid over the hold period vs. rent paid over the same period

• Equity built through amortization

• Home price appreciation over the hold period

• Opportunity cost of the down payment at a reasonable alternative investment rate

• Tax benefit of the mortgage interest deduction, which phases out above certain income levels and is capped at $750,000 in loan principal under current law

In San Diego, Orange County, and Silicon Valley markets, with home prices in the $900,000 to $2 million range, the break-even under moderate appreciation assumptions commonly falls between 6 and 10 years. Buyers who are confident they will stay in the home for at least that long are making a sound financial bet on ownership. Buyers with a 3 to 5 year horizon are taking on meaningful risk that they exit before the math clears.

What This Does Not Mean

Breaking even later than expected does not mean buying is wrong. It means the time horizon matters, and buyers should be honest about theirs.

Ownership provides stability, the ability to modify and improve the property, protection against rent increases, and a forced savings mechanism that many households benefit from. These are real and legitimate reasons to buy. The financial break-even analysis does not capture all of that value.

What it does capture, clearly, is that buying a home in a high-price California market is not a decision that pays off quickly. Enter with realistic expectations about the timeline, and the decision is well-informed.
