Stop Renting — Here’s the Math No One Shows You

The honest answer is that buying beats renting when the price-to-rent ratio is under roughly 15, renting wins when it climbs above 20, and everything in between depends on how long you plan to stay. That ratio, the home price divided by a year of rent, is the number your parents never used and every lender hopes you never find.

Every "rent is dead money" line skips the part where a mortgage is mostly interest for the first decade, ownership carries taxes, insurance, and maintenance that often run 1 to 3 percent of home value each year, and a home is not liquid when you need cash fast.

What is the price-to-rent ratio, exactly?

It is the price of a home divided by one year of rent for the same home. A $300,000 home renting for $1,500 a month has a ratio of 300,000 divided by 18,000, or 16.7. Historically, anything under 15 favors buying, and anything above 20 strongly favors renting.

How do maintenance and taxes change the math?

Owners commonly spend 1 to 3 percent of the home value per year on upkeep and repairs. Add property taxes and insurance, and a 6 percent mortgage payment can mean a real cash cost well above the rent on an identical place, especially in the early years when interest dominates.

When does renting win?

• You plan to move within three to five years and closing costs would wipe out the gain
• The price-to-rent ratio is above 20 in your city
• You want flexibility to change jobs or cities without selling
• Your savings would be gutted by the down payment and emergency fund disappears
• The rent is low and you can invest the difference

When does buying win?

Buying wins when you expect to stay at least five to seven years, the price-to-rent ratio is under 15, and you can afford the down payment without emptying the emergency fund. Over that horizon, paying down a mortgage builds equity and historically home appreciation has tracked inflation plus a bit.

What does the real total look like?

The famous comparison is a five-year stay on a median-priced home. Count the down payment, closing costs, mortgage interest, taxes, insurance, and maintenance against the same years of rent. The landlord pays the same building costs; your rent simply includes them in one transparent monthly number.

The bottom line

Do the ratio math before you follow the chorus. If the ratio is under 15 and you will stay five-plus years, buying is the move. Above 20, renting and investing the difference is the disciplined play. And in between, the tiebreaker is how long you plan to stay, not how loudly people say rent is dead money.
