Rent vs Buy in Miami in 2026: The Breakeven Math

Last updated: July 2026

The honest answer on rent versus buy in Miami in 2026 is that renting wins on carrying cost in most scenarios running today, and buying wins only if you hold long enough for principal paydown, the Save Our Homes assessment cap, and price growth to overcome roughly seven to eight percent in round trip transaction costs. At a 30-year fixed rate of 6.58% as of July 23, 2026 [1], a 20% down purchase at the Miami-Dade condo median of $431,000 [2] carries at about $3,990 a month before any tax benefit, against a countywide two-bedroom Fair Market Rent benchmark of $2,436 [3]. That gap does not close from cash flow. It closes from appreciation, and only over a long hold.

The real question is how many years of price growth it takes to erase that spread plus the closing costs on both ends. Below is the framework, the current inputs, and two worked examples with every assumption labeled. Run it with your own rent and your own insurance quote before you decide.

The framework

Ownership carrying cost is five line items, not one:

Principal and interest
Property tax at the applicable millage, after homestead exemption
Insurance, meaning homeowners plus wind plus flood, or a condo unit policy plus what the master policy passes through
HOA or condo dues, where applicable
A maintenance reserve, which is real whether or not you fund it

Subtract the portion of the payment going to principal, since that is a transfer to your own balance sheet rather than an expense. What remains is the economic cost of owning. Compare it to rent on a comparable unit, layer in transaction cost drag, then solve for the holding period.

Current inputs

Mortgage rate. Freddie Mac's Primary Mortgage Market Survey put the 30-year fixed at 6.58% for the week of July 23, 2026 [1].
Prices. Miami-Dade single-family median sale price was $695,000 in June 2026, up 3.73% year over year, with 4.9 months of supply. The condo median was $431,000, down 3.15% year over year, with 12.3 months of supply [2].
Rents. HUD's FY2026 Fair Market Rents for the Miami-Miami Beach-Kendall area are $1,995 for a one-bedroom, $2,436 for a two-bedroom, and $3,127 for a three-bedroom [3]. These are 40th-percentile standard-quality gross rents and sit below what newer urban-core buildings ask, so substitute your actual rent.
Millage. The Property Appraiser's 2025 proposed millage rate table shows a combined rate of 20.0180 mills inside the City of Miami and 16.9335 mills in unincorporated Miami-Dade, of which 6.4990 mills is school board [4].
Insurance. Florida's Office of Insurance Regulation announced that Citizens Property Insurance policyholders would see an average statewide reduction of 8.7% beginning in spring 2026, with about 42,000 Miami-Dade homes averaging a 14.0% reduction [5]. Direction of travel is helpful, but you still have to quote the specific property. NFIP flood pricing under Risk Rating 2.0 is set per building using first floor height, distance to flood sources, and rebuild cost [6], so two houses on the same block can price very differently.

Worked example one: a median-priced condo

Assumptions labeled. Purchase price $431,000 [2], 20% down, $344,800 loan, 30-year fixed at 6.58% [1], City of Miami millage of 20.0180 [4], homestead exemption applied.

| Line item | Monthly |

|---|---|

| Principal and interest | $2,198 |

| Property tax (about $7,780 per year) | $648 |

| Condo association dues (illustrative assumption) | $900 |

| HO-6 unit policy (illustrative assumption) | $150 |

| Interior maintenance reserve (illustrative assumption) | $90 |

| Total carrying cost | $3,986 |

| Less year-one principal paydown | ($317) |

| Economic cost of ownership | $3,669 |

Against the $2,436 two-bedroom benchmark [3], the spread is about $1,233 a month, or roughly $14,800 a year. The $86,200 down payment also stops earning elsewhere, which at an illustrative 4% real return is another $3,450 a year.

One note on the tax line. Florida resets assessed value to just value in the year after a sale, so year one is the expensive year. The first $25,000 of homestead exemption applies to all levies; the second portion, $50,722 in total exemption value for 2025 and indexed to CPI thereafter, does not apply to school levies [7].

Worked example two: a median-priced single-family home

Purchase price $695,000 [2], 20% down, $556,000 loan at 6.58% [1], unincorporated Miami-Dade millage of 16.9335 [4], no HOA.

| Line item | Monthly |

|---|---|

| Principal and interest | $3,544 |

| Property tax (about $11,080 per year) | $923 |

| Homeowners with wind plus flood (illustrative assumption) | $600 |

| Maintenance reserve at 1% of value (illustrative assumption) | $579 |

| Total carrying cost | $5,646 |

| Less year-one principal paydown | ($510) |

| Economic cost of ownership | $5,136 |

Against the $3,127 three-bedroom benchmark [3], the spread is about $2,009 a month, or roughly $24,100 a year.

Transaction costs on both sides

Renting costs a security deposit and a move. Buying costs materially more, and Miami-Dade has a quirk. Florida documentary stamp tax on deeds is 60 cents per $100 in Miami-Dade, plus a 45 cent per $100 surtax on transfers of anything other than a single-family dwelling [8]. A condo pays $1.05 per $100 and a house pays $0.60, so about $4,525 on the condo resale and $4,170 on the house. Notes and mortgages carry 35 cents per $100 [8].

Add brokerage compensation, which is negotiable and set by agreement, plus title, lender fees, and inspections. At an illustrative 5% sell-side brokerage cost, the condo round trip is roughly $34,600, or about 8% of price. The house is roughly $48,500, or about 7%.

Breakeven holding period

Amortize the round trip over the hold, then add the annual carrying gap. For the condo, $14,800 a year of spread plus about $4,900 a year of amortized transaction cost over a seven-year hold means price growth must produce roughly $19,700 a year on a $431,000 asset. That is about 4.5% compounding annually for seven years just to draw even with renting. The house lands in a similar range.

That is the number to argue with. It is neither obviously achievable nor obviously out of reach. What it is not is automatic.

How Save Our Homes changes the math over a long hold

Once a property is homesteaded, the annual increase in assessed value is capped at 3% or the change in CPI, whichever is lower. The Florida Department of Revenue set the 2026 cap at 2.7% [9]. The cap does nothing in year one. It compounds.

Illustrative arithmetic: if market value on the $695,000 house grew 6% a year while assessed value grew at the 3% ceiling, after ten years market value would be about $1,244,000 and assessed value about $934,000. At 16.9335 mills [4], that wedge is worth roughly $5,300 a year in avoided tax, and it keeps widening. It is the strongest structural argument for owning a Miami primary residence over a long horizon, and the reason short and long holds produce different answers.

It is also why the cap is worth nothing to a buyer moving in three years, and nothing at all on a property that is not your homestead.

Where the answer flips: condo versus single-family

The condo math is dominated by association dues. That money is a pure expense. It builds no equity, it is not capped by Save Our Homes, and it has been rising across the county as buildings fund milestone inspections and structural integrity reserve studies. Underwrite the reserve study and the special assessment history, not just the current fee.

Market context reinforces it. Condo inventory sat at 12.3 months of supply in June 2026 with the median down 3.15% year over year, while single-family sat at 4.9 months with the median up 3.73% [2]. Requiring 4.5% annual appreciation from an asset class currently printing negative year-over-year price change is a hard underwrite. In Brickell and similar dense condo submarkets, renting is the defensible answer for most holds under five to seven years.

The single-family math is heavier in absolute dollars but structurally friendlier over a long hold. Land is the appreciating component, maintenance timing is discretionary, there is no association fee, and the Save Our Homes wedge compounds. In submarkets such as Pinecrest, a buyer with a ten-year horizon and a firm insurance quote is running a different calculation than a three-year condo buyer.

Neither result is a recommendation. They are outputs of assumptions, and yours will differ. To run the framework against a specific property, rent, and insurance quote, that is what a buyer consultation is for.

Frequently asked questions

Does the mortgage interest deduction change the answer?

It can, but less than most people assume, because the standard deduction and the cap on state and local tax deductions limit the benefit for many filers. Nothing above assumes any tax benefit. Ask a CPA to run your return before counting on it.

Why is the property tax so high in year one?

Florida reassesses to just value in the year following a sale, so the seller's capped assessed value does not transfer to you. If you are moving from another Florida homestead, portability of accumulated Save Our Homes benefit may reduce this, subject to statutory limits. Confirm eligibility with the Property Appraiser.

Is flood insurance always required?

Lenders require it in high-risk flood zones. Outside those zones it is optional and often still worth carrying. Because Risk Rating 2.0 prices per building rather than per zone [6], the only useful number is a quote on the specific address.

What holding period actually makes buying work in Miami?

On the assumptions above, roughly seven years or longer, and the longer the hold the stronger the case, mostly because of the Save Our Homes cap and principal amortization. Under five years, renting is usually the cleaner answer on cost alone.
