What Is a Good Price-to-Rent Ratio?
How to read price-to-rent ratio bands, why 15 and 20 are the usual cutoffs, and what the number leaves out when you compare buying with renting.
The three-band rule of thumb
Most guides split the price-to-rent ratio into three bands. At 15 or below, homes look cheap relative to what landlords charge, so buying tends to build equity faster than paying rent. Between 16 and 20 the two paths run close together, and the decision turns on your plans and local costs rather than the ratio alone. Above 20, rents are low compared with prices, which often makes renting the more efficient use of cash. These bands are a screen, not a verdict.
Why 15 and 20 are the cutoffs
The 15 and 20 markers are a widely repeated rule of thumb rather than an official rule. They spread through real estate research and personal finance coverage as a quick way to compare markets on a single scale. Because rents, mortgage rates, and taxes shift over time, the exact lines have wobbled in different eras and cities. Use them as reference points that flag when a market leans clearly one way, not as precise thresholds.
What a low or high ratio really tells you
A low ratio signals that a monthly mortgage could rival or beat local rent, but it can also flag a soft market where prices have fallen for a reason worth investigating. A high ratio means renting is cheap next to buying, which can reflect an expensive, high-demand city or a stretch of rapid price growth. In both cases the ratio points you toward the right question rather than answering it. Look at why the number sits where it does before drawing a conclusion.
What the ratio leaves out
The ratio compares one price to one year of rent and nothing else. It ignores the mortgage interest you would pay, property taxes, insurance, maintenance, closing costs, and the equity or appreciation a purchase might earn. It also assumes you stay long enough for buying to pay off, which is often the deciding factor. Run a full rent-versus-buy calculation once the ratio has told you which way a market leans.
