Compare the true financial impact of buying a home versus renting. We factor in property taxes, HOA/maintenance, closing costs, and opportunity cost to give you a mathematically accurate comparison.
Due to the high sunk costs of buying, renting and investing the difference yields a higher net worth.

The phrase "renting is throwing money away" is one of the most pervasive myths in personal finance. In reality, both buying and renting involve throwing money away on unrecoverable costs.
For renters, the unrecoverable cost is rent. For buyers, the unrecoverable costs are mortgage interest, property taxes, HOA fees, maintenance, and closing costs. Our true-cost calculator factors in all these elements.
A great mental model for the Buy vs Rent decision is the 5% Rule. This rule states that the unrecoverable costs of homeownership generally average out to 5% of the property's value every year.
If your annual rent is strictly less than 5% of the home's value, renting is usually the superior financial decision. For a $400,000 home, 5% is $20,000/year or roughly $1,667/month. If you can rent a similar home for less than this amount, the math strongly favors renting.
When you buy a house, you tie up a massive amount of cash in a down payment and closing costs. If you had rented instead, you could have invested that exact same initial capital in the stock market (e.g., via an S&P 500 index fund) and earned a historical average return of 8-10% annually.
Furthermore, if your monthly mortgage, taxes, and maintenance combined are higher than your monthly rent, a disciplined renter can invest that difference every single month. Over 30 years, this invested difference compounds exponentially.
Buying a home generally becomes the superior financial choice if you plan to stay in the home for a long time (typically passing the "break-even" year calculated above). The longer you stay, the more the loan amortization shifts in your favor (you pay more principal and less interest), and the more time your home's value has to appreciate to offset the initial heavy closing costs.
No. The decision depends heavily on how long you plan to stay in the home, the local housing market, and mortgage rates. Buying involves significant sunk costs (closing costs, maintenance, property taxes, interest) that can outweigh the equity gained if you move within 5-7 years.
When you put 20% down on a house, that money is tied up in the home. If you had rented instead and invested that same 20% down payment into an S&P 500 index fund, it would likely compound at 8-10% annually. This lost investment growth is the opportunity cost of buying.
Property taxes, HOA fees, and maintenance are ongoing, unrecoverable costs of homeownership. They typically average 1.5-2.5% of the home's value annually. In a true Buy vs Rent calculation, these costs must be factored into your monthly outlay to find your true net worth.
The 5% Rule is a quick rule of thumb for estimating the unrecoverable costs of homeownership. It estimates that property tax (1%), maintenance/HOA (1%), and cost of capital/interest (3%) will cost about 5% of the home's value each year. If your annual rent is strictly less than 5% of the home's value, renting may be better financially.
