Every buyer eventually asks the same question: am I better off renting or buying right now? Usually it's answered with a calculator, a 30-year mortgage schedule, and a lot of hand-waving. We prefer data.
We pulled every active rental listing and every closed sale across 147 South Florida zip codes (Miami-Dade, Broward, Palm Beach), calculated a price-to-rent (P/R) ratio for each, and mapped the results. The pattern is cleaner than we expected — and it inverts what most locals assume about their own neighborhoods.
The price-to-rent ratio is the median sale price of a home divided by 12 months of median rent for comparable properties in the same zip. A widely used interpretation:
This is not a law of physics. Rent controls, HOA dues, insurance shocks, and tax differentials between primary-residence and non-homestead can shift the break-even by 20-30%. But as a first filter across 147 zip codes, it's a remarkably clean signal.
Two visual patterns jump out:
These zip codes have at least 30 closed sales and at least 30 rental listings in the past year — enough data for both sides of the ratio to be stable.
Pattern: condo-heavy zip codes are buy-favored in 2026 because sale prices compressed faster than rents did. If you're a buyer with flexible credit, cash for reserves, and patience to absorb HOAs, these are the zips where mortgage + taxes + insurance is already cheaper than writing a rent check.
Pattern: established luxury single-family zip codes are rent-favored because the rental market never kept up with 2021-2025 sale-price appreciation. Renters in these zips are genuinely getting a deal — they pay 3-4% of asset value per year instead of the 5-6% an owner would pay in carrying costs.
A fair test: if the P/R signal is real, we should see higher ownership rates in the "cheap to buy" zips and lower ownership rates in the "expensive to buy" zips. We matched our P/R data to the 2022 ACS homeownership rate from the U.S. Census for every zip in our sample:
The relationship is visibly negative and statistically meaningful. Zips with P/R < 12 typically show ownership rates of 60-75%. Zips with P/R > 25 show ownership rates of 40-55%. Households aren't making this choice because they read a P/R article — they're making it because the monthly cash-flow math pushes them toward rent when owning stops making sense.
The neighborhoods where your friends keep saying "I'd love to buy here but it doesn't pencil out" are, statistically, exactly the neighborhoods where renting is in fact the smarter play. The people already living there figured it out first.
Only if prices rise enough. If the condo in South Beach you buy today for $500K is worth $500K in five years (very plausible given the ongoing correction), you built zero equity beyond your principal paydown minus transaction costs. The renter next door who put the would-be down payment into an index fund at 7% annualized for five years is ahead by roughly $40K net-net, adjusted for everything. The P/R framework assumes zero price appreciation, which is the most honest baseline in a correcting condo market.
These are already priced into the rental market. When HOAs double in a building, the owner's cost rises — but so does the rent a new tenant pays, because the landlord passes it through. In 2024-2026 Miami, HOA and insurance doubled both for owners and (via rents) for tenants. That's why the ratio framework still works: both sides of the fraction move together.
Where it breaks: primary-residence homestead exemptions (available only to owners) can shave 15-25% off your effective carrying cost and shift a marginal 18-20 P/R zip into clear buy territory. Worth running the numbers on a specific address.
Don't buy. At any P/R ratio above ~12, two years of ownership costs (closing costs, selling costs, transaction friction, interest-heavy early-year mortgage payments) eat your equity before appreciation has time to compound. Buy only when you have reason to believe you'll be in the home for 5+ years, period.
Completely valid. Owning lets you paint the walls, keep a dog, not have a landlord, and anchor to a place. The P/R framework is only about the financial comparison — not about whether ownership is worth it for you personally. If a zip has P/R = 30, you're paying a 50% premium for those non-financial benefits. Decide if it's worth it.
A practical path, in order:
The single most common mistake we see is buying in a P/R > 25 zip because "it's a great neighborhood" without recognizing that the great neighborhood is priced into the sale but not into the rent. The fix is simple: acknowledge you're paying a premium for the neighborhood, decide if it's worth it, and move on.

Sale side: every closed residential sale in the last 12 months. Ratios computed at the 5-digit zip-code level. Zips included: those with at least 30 observations on both the sale side and the rental side — 147 zips met that bar.

Price-to-rent ratio formula: median sale price ÷ (median monthly rent × 12). Interpretation thresholds follow widely-used conventions (P/R < 15 buy-favored, > 20 rent-favored); they are heuristics, not laws.
