Rent vs. Buy in Miami (2026): The Honest Math

Miami is the first city in this series that needs two answers. At July 2026 figures our engine gives the same verdict to both, through opposite mechanisms: a ten-year stay in the median $680,000 single-family home finishes $70,723 behind renting the comparable house, and a ten-year stay in the median $410,000 condo finishes $70,731 behind renting a comparable two-bedroom. Every figure comes from our rent vs buy calculator at dated, editable inputs, with a second preset for the condo case.

Data last updated: July 2026. Rate anchor: Freddie Mac’s Primary Mortgage Market Survey 30-year fixed at 6.49 percent, week of July 9, 2026.

Those two gaps land eight dollars apart, which is coincidence, but the causes are not. The house loses on taxes and wind insurance. The condo loses on $900 a month of dues plus a risk no monthly number captures: the special assessment, routinely $20,000 to $100,000-plus per unit in older buildings now that Florida’s reserve-funding rules are in force. This page prices both, separately, because averaging them would misprice each.

What does the Miami market look like in mid-2026?

Split down the middle. Single-family homes are appreciating: the metro median sale price is about $680,000 (Redfin, March 2026, up 3.8 percent year over year), with the Miami Association of Realtors’ single-family median of $671,250 corroborating it. Condos are the opposite market: the overall condo median is about $410,000 with prices flat to declining, inventory near 14 months of supply, and the median down roughly 10 percent year over year in January 2026 reporting. One widely quoted number deserves a label: the $880,000 condo figure from early 2026 is a luxury-skewed AVERAGE dragged up by new waterfront towers, not the median condo a typical buyer prices.

Rents split by segment the same way. Zumper’s median house rent is $3,450 (July 11, 2026, with the $3,800 three-bedroom median corroborating the tier). Two-bedroom figures scatter from Apartment List’s $1,868 county tracker through Rent.com’s $2,833 and RentCafe’s $2,986 to Zumper’s downtown-weighted $3,167; our condo preset uses $2,900 from the middle of that band, and the rent ladders below price both edges.

Why does this page have two answers?

Because in Miami the property type changes the cost structure, not just the price. A house carries its own roof: you pay the wind premium directly ($550 a month in our preset) and the 1 percent maintenance reserve, but no dues. A condo pushes the roof, the master insurance policy, and the structure into the association: your direct insurance shrinks to a $250 HO-6 policy and maintenance to 0.75 percent, but $900 a month of dues arrives, and with it the balance-sheet risk of everyone else’s deferred repairs. The neighborhoods sort accordingly: Brickell, Edgewater, and Miami Beach are the condo market this page’s second preset prices; Coral Gables, South Miami, Kendall, and West Miami-Dade are the single-family market the first one prices.

What is Miami-Dade’s real property tax for a new buyer?

About 1.59 percent effective on the house and 1.80 percent on the condo, and since those numbers sit far above the ~1.0 percent averages circulating online, here is the arithmetic from primary sources. The 2025 adopted millage (Miami-Dade Property Appraiser) totals 16.9317 mills in unincorporated Miami-Dade, where Kendall’s single-family value pockets sit, and 19.9878 mills in the City of Miami, where Brickell’s condos sit; schools are 6.6330 mills of each. A homesteaded buyer takes $25,000 off all levies and another $25,000 off the non-school levies. On the $680,000 house: $655,000 times the school mills plus $630,000 times the rest equals $10,833 a year, or 1.59 percent of the price. On the $410,000 condo at city millage: $7,361 a year, 1.80 percent.

The ~1.0 percent figure is not wrong so much as it is someone else’s rate. Florida’s Save Our Homes cap limits a homesteaded ASSESSMENT to 3 percent growth a year, so owners who bought a decade ago pay far below today’s millage-times-market arithmetic, and county averages blend all of them. Your assessment resets to market value the January after you buy. One genuine relief valve exists: Florida law (s. 193.011(8)) lets appraisers net out typical costs of sale, which often lands assessments below the sale price; the ladder prices that case too.

Note what the top row says: even at the retired 1.0 percent, breakeven is year 12, outside the 7-to-11-year range the 2026 research briefs estimate. The tax resolution explains part of Miami’s delta, not all of it.

What does buying the house cost per month?

Owning the $680,000 house costs $5,453 a month in cash at the preset; renting the comparable house costs $3,465 with renters insurance. The stack: $3,434.87 of principal and interest on the $544,000 loan (6.49 percent, 30 years), $901 of property tax, $550 of wind-inclusive insurance, and $566.67 of maintenance reserve at 1 percent of value.

In month one, $492.74 of the payment pays down the loan and $2,942.13 is interest, so owning’s unrecoverable cost is $4,959.80 against the renter’s $3,465. Across year one the balance falls by $6,092 while $35,127 goes to interest.

What does buying the condo cost per month?

Owning the $410,000 condo costs $4,092 a month; renting the comparable two-bedroom costs $2,915. The stack reads differently: $2,071.03 of principal and interest on the $328,000 loan, $615 of property tax, $250 of HO-6 insurance, $256.25 of interior maintenance, and $900 of HOA dues. The dues are the second-largest line, bigger than tax, insurance, and maintenance, because they carry the building’s master wind policy and, since January 1, 2026, its fully funded structural reserves.

How much cash does each purchase take upfront?

The house takes about $157,080: a $136,000 down payment plus $21,080 of closing costs at 3.1 percent. The condo takes about $96,555: $82,000 down plus $14,555 at 3.55 percent. Both closing rates run above the series’ plain 2.5 because of a Miami-Dade quirk worth knowing before you write an offer: local custom assigns Florida’s documentary stamp tax on the deed to the BUYER here, backwards from the rest of the state. Single-family homes pay $0.60 per $100 and are exempt from the county’s $0.45 surtax; condos pay both, $1.05 per $100 (Florida Department of Revenue). That is $4,080 of the house’s closing line and $4,305 of the condo’s, and it is why the condo’s percentage is higher even though its price is lower.

When does buying break even?

Year 16 for the house and year 18 for the condo, in each preset’s base case, which means neither crosses inside the 15-year window our charts draw. At the shared ten-year tenure, renting finishes $70,723 ahead on the house and $70,731 ahead on the condo. The July 2026 research brief estimated 7 to 11 years for houses and 10 to 14 for condos; the engine lands well past both once the new-buyer tax rate, the insurance band, and the buyer-paid stamp are priced. For the house, even the brief’s own tax assumption only reaches year 12 (first table above), and the rest of the gap is the compounding renter-side opportunity cost these estimates habitually under-weight.

Notice the shape difference. The house gap CLOSES steadily after year 7 because 3 percent appreciation on $680,000 eventually outruns the carrying costs. The condo gap barely moves, because 2 percent appreciation on $410,000 is $683 a month gross while the dues alone eat $900. A condo at these numbers is not a slower version of the house trade; it is a different trade.

What would a special assessment do? (The condo centerpiece)

Erase years of progress in one letter from the board. Since January 1, 2026, Florida condominium associations must fund structural reserves in full and complete milestone inspections under SB 4-D (2022) and HB 1021 (2024), the post-Surfside safety laws. Buildings that deferred maintenance for decades are now billing it, and per-unit special assessments of $20,000 to $100,000-plus are routine in older towers. Our engine has no crystal ball for your building, so the ladder prices the hit directly: a one-time assessment landing in year 3, added to the cumulative cost of owning from that year on.

Read the last row twice: a $100,000 assessment, which post-2026 inspection reports have produced in older coastal buildings, moves breakeven to year 23 and hands renting a $170,731 lead over a ten-year stay. This is why the condo answer cannot be an average. A verified, fully reserved building lives on the first row; an unverified 1980s tower might live on the last.

What if the HOA keeps rising instead?

The slow version of the same problem costs almost as much. Miami condo dues have been rising 3 to 5 percent a year as reserve funding phases in, and some buildings are seeing more. Our calculator holds HOA flat, so the ladder prices each growth path as the flat monthly amount with the same ten-year total (a labeled approximation: it front-loads the cost slightly, and past year 10 it understates a still-escalating fee, so late breakevens read optimistic).

The symmetry with the assessment table is the honest takeaway: a 5 percent dues escalation costs a ten-year owner about as much as a $50,000 one-time assessment. Reserves get funded either way; the only question is whether the bill arrives as a lump or a drip.

What about condo prices falling further?

Then buying does not break even at all. The preset already uses 2 percent appreciation for flat-to-declining stock, but the condo market was printing DECLINES in early 2026, so the ladder prices those too:

What should a condo buyer demand before offering?

Documents, in this order, before emotional attachment sets in. All of these exist because of the 2022-2024 safety laws; a seller or association that cannot produce them is telling you the answer.

That last row is the quiet one. Since the reserve rules took hold, a meaningful share of older buildings fail conventional lending standards, which pushes buyers into portfolio loans at higher rates and larger down payments than our preset’s 6.49 percent and 20 percent. If the building is non-warrantable, your real numbers are worse than every table on this page.

How big is the insurance line, really?

Florida’s statewide average homeowners premium reached $8,292 in 2025, up 18 percent in a year and roughly 181 percent above the U.S. average, with Insurify projecting $8,458 by year-end 2026 and Miami-Dade’s coastal quotes running above the state line. Two pieces of relief are real: Citizens Property Insurance filed rate CUTS at spring 2026 renewals, 8.7 percent statewide and about 14 percent in Miami-Dade and Broward, and wind-mitigation credits remain substantial on newer or retrofitted construction. Our house preset’s $550 a month ($6,600 a year) deliberately sits below the statewide average to represent a newer, wind-mitigated inland house; the ladder shows what any other quote does. Flood insurance is a separate policy on top and is NOT in the preset: FEMA’s Risk Rating 2.0 repricing has legacy premiums rising 15 to 18 percent a year, and a coastal AE or VE zone can add four or five figures annually. Quotes before offers, always.

What rent would change the answer?

For the house, only an above-median comparable moves the verdict inside a normal horizon; for the condo, apartment-tracker rents make buying unreachable entirely.

Per our series’ comparable-rent standard, each preset’s rent matches the tier being bought: the $3,450 house median for the $680,000 house, and a $2,900 vendor mid-band for the $410,000 condo, because Zumper’s $3,167 city figure leans on Brickell towers that sell far above $410,000. If your realistic alternative is one of the cheaper rows, renting wins by even more; that is the whole message of the ladder.

What about conservative and buyer-favorable scenarios?

One row rewards attention: at the shared 3 percent appreciation, the CONDO breaks even before the house (year 13 versus 16), because its price-to-rent ratio is lower (11.8 versus 16.4). Miami’s condo problem was never the rent math; it is that 3 percent appreciation is not what older condo stock is doing, and the dues and assessment risk sit on top.

Which neighborhoods map to which answer?

From the July 2026 research, as labeled starting points. Brickell and Edgewater are the condo preset with high dues and tower supply; Miami Beach is the condo preset with the metro’s worst insurance quotes layered on. Coral Gables and South Miami are single-family premium (medians well above $1.2 million, so scale the preset up before trusting it). Kendall and West Miami-Dade are the single-family value pockets closest to this page’s $680,000 case, at unincorporated millage. Little Havana and Allapattah are the entry and gentrifying tier where both property types mix and per-building diligence matters most.

Who should buy here, and who should keep renting?

Buying the house fits a household committed to Miami for well over a decade, with the $157,080 upfront available, a wind-mitigated target (or the budget to retrofit one), and a real insurance quote in hand before the offer. Buying the condo fits a narrower profile: the same long horizon PLUS a building that passes the entire checklist above, in which case the first row of the assessment table is yours and the rent math is actually favorable. Keep renting if your horizon is under ten years (both variants), if the only condos you can afford fail their SIRS review, or if a five-figure assessment would break you; renters carry none of the reserve risk, which in 2026 Miami is worth real money. No state income tax applies to renters and owners alike, so it sets the cost of living here, not this verdict. Before committing, confirm the payment with the home affordability calculator, see the amortization in the mortgage calculator, and price the invested-cash side with the compound interest calculator.

How do you run your own numbers?

Open the house preset or the condo preset and the July 2026 figures load, dated and fully editable. For the house, replace two fields with real numbers: the wind quote for the actual address, and the rent of the house you would truly live in. For the condo, replace three: the building’s actual dues, your lender’s actual rate (higher if the building is non-warrantable), and, if the estoppel shows a pending assessment, add its monthly share to the HOA field. For the Florida sibling where insurance is the whole story, read Tampa; for what a genuinely low tax does to the same math, Denver; for the full ten-city picture, the rent vs buy by city comparison.

Methodology, assumptions, and limitations

Every figure comes from the FinExplained calc engine, the same tested decimal-math code that powers the rent vs buy calculator, run at the two Miami presets. The model accumulates costs year by year, credits the buyer with sale proceeds net of selling costs and the loan payoff, credits the renter with compound growth on the upfront cash, and reports the first crossover year. The special-assessment ladder adds a one-time cost to the ownership path from year 3 onward without compounding it, and the HOA-growth ladder converts escalating dues to a ten-year-equivalent flat amount; both approximations are labeled where they appear and both lean slightly in buying’s favor. How we source, verify, and correct our work is on our methodology page.

The single most useful next step depends on which Miami you are pricing. House: get the wind and flood quotes for the exact address, then run them through the house preset. Condo: request the SIRS, the reserve study, and the estoppel before you fall in love with the view, then price what they say in the condo preset. In this market, the documents are the decision.
