Rent vs. Buy Calculator: Is It Better to Buy in Miami, FL?

Florida taxes and what they mean for your decision

Florida has no state income tax, a major driver of the wave of relocations from New York and other high-tax states in recent years, though Miami's property tax rate of 1.0% is close to the national average.

The Miami, FL rental market

Miami's rental market has been reshaped by significant international and domestic in-migration since 2020, pushing rents up sharply — though as with Jacksonville, Florida-wide insurance cost increases are an important factor not fully captured in this calculator's standard maintenance assumptions.

What makes Miami different

Miami's elevated price-to-rent ratio reflects strong investor and international buyer demand, which can decouple home prices from what local incomes alone would support — run a conservative appreciation assumption here rather than extrapolating recent years' gains.

Miami, FL's price-to-rent ratio: 22×

Dividing the median home price by annual rent for an equivalent home gives the price-to-rent ratio — a quick screening tool used by economists and real estate analysts. A ratio below 15 generally favours buying, 15–20 is a genuine toss-up, and above 20 generally favours renting, all else being equal. Miami, FL currently sits at approximately 22×, which leans toward renting unless you plan a long holding period or expect above-average appreciation.

These are metro-level estimates for illustration. Use the calculator above with your specific neighborhood, property, and rental comparison for an accurate result.

True upfront cost of buying in Miami

The down payment is only the beginning. Closing costs on a $520,000 home in Miami, FL typically run an additional 2–4% of the purchase price — meaning a buyer putting 20% down should realistically plan to bring $119,600–$130,000 to closing, not just the $104,000 down payment. These upfront costs are one reason the break-even period for buying is measured in years, not months: you have to accumulate enough equity and appreciation to recover the closing costs before you come out ahead versus renting.

Estimates. Closing costs vary by lender, title company, and whether the seller agrees to pay any costs. Some buyers negotiate seller concessions of 2–3% to reduce cash needed at closing.

The renter's alternative: investing the down payment and monthly difference

The rent-vs-buy question is not just about monthly housing costs — it's about what you do with the money you don't put into a home. A renter in Miami, FL who avoids tying up $104,000 in a down payment and instead invests that sum in a diversified index fund earning 7% annually would have approximately $204,584 after 10 years and $791,675 after 30 years — before taxes on gains. Whether that outcome exceeds the equity and appreciation of buying depends heavily on Miami's home price growth, which historically varies significantly by neighbourhood and economic cycle.

Renters also retain flexibility: the ability to move for a job, a relationship, or a better neighbourhood without paying the 5–6% real estate commission and closing costs that erode equity on every sale. At Miami, FL's current price-to-rent ratio of 22×, the monthly cost of renting an equivalent home is materially lower than the all-in ownership cost — leaving substantial room to invest the monthly difference.

Neither choice is universally correct. Buyers build equity, get the leverage of a mortgage (a 5% home value increase on a 20%-down purchase represents a 25% return on invested capital), and lock in their housing cost with a fixed-rate mortgage. Renters retain liquidity and flexibility. The calculator above quantifies these trade-offs with your specific numbers — the price-to-rent ratio and break-even year are the two most important outputs to examine for your Miami, FL decision.
