Miami Condo Carrying Costs in 2026: The Full Monthly Math

Last updated: August 2026

Miami condo carrying costs in 2026 are principal and interest plus four other line items: the monthly association assessment, HO-6 unit-owner insurance, property tax calculated on the post-sale assessed value, and any special assessment currently being collected. On a median-priced unit that non-mortgage stack runs roughly $1,600 a month before a single dollar of special assessment, which is close to what principal and interest cost on the same unit. Miami-Dade's existing condo median sale price in July 2026 was $400,000 [1]. Apply the City of Miami's 2025 adopted total millage of 19.9878 mills [2], Citizens Property Insurance's current average multi-peril HO-6 premium for Miami-Dade of $1,369 a year [3], and a metro-median association due of $835 a month [4], and the non-mortgage components work out to about 44 percent of the total monthly outlay in the illustration below. That share is what a listing-portal payment calculator leaves out, and it is what a lender underwrites. The building's cost structure, not the purchase price, usually decides whether a unit is affordable.

What the non-mortgage stack is made of

The regular association assessment

The monthly assessment funds two separate things: the association's operating budget (insurance on the building, management, utilities for common areas, staffing, elevators, fire protection systems) and its reserve contributions. Since Senate Bill 4-D and the statutes that followed it, the reserve line is no longer discretionary for the components covered by a structural integrity reserve study. Florida Statutes section 718.112 provides that for a budget adopted on or after December 31, 2024, the members of a unit-owner-controlled association that must obtain a structural integrity reserve study may not vote to provide no reserves, or less reserves than required, for the items the statute lists [5]. A line that boards used to waive is now a line they have to fund.

Redfin's analysis of Florida condo dues put Miami's median monthly association fee at $835, higher than any of the other 43 U.S. metros in that study [4]. That is a metro-wide median from mid-2024, and assessments in many Miami-Dade buildings have moved up since. Treat any published median as a reference point and read the actual budget.

HO-6 unit-owner insurance

The association's master policy covers the structure and common elements. HO-6 covers what is inside your unit: interior finishes, personal property, personal liability, and loss assessment coverage that responds when the association levies a covered assessment. Citizens Property Insurance, the state-backed insurer, reported a current average multi-peril HO-6 premium in Miami-Dade of $1,369 a year in its 2026 recommended rate filing, with a recommended reduction to $1,228, based on policies in force as of April 30, 2025 [3]. That is roughly $114 a month. Units in wind-only rating territories carry a separate wind policy that prices materially higher, and a county average is not a quote for any specific unit.

Property tax at the reset value

This is the line buyers most often get wrong. Florida's assessment caps limit how fast an existing owner's assessed value can rise, and those caps reset when the property changes hands, so the seller's tax bill is not a preview of yours. Millage also varies by municipality, and the Property Appraiser publishes the adopted chart every year, so comparable units a few miles apart can carry different tax rates on the same value [2].

Special assessments

A special assessment is separate from the regular fee. It is a one-time or multi-year levy for a specific project: a milestone inspection repair, a facade or balcony program, a roof, a garage restoration. It is often collected monthly for years, and, as covered below, underwriting counts it.

Running the stack on a median-priced unit

The arithmetic below is a clearly labeled illustration, not a quote. Mortgage rates change constantly, so check the current Freddie Mac Primary Mortgage Market Survey before running your own version.

At a hypothetical 6.5 percent on a 30-year fixed loan, a $400,000 purchase with 20 percent down produces a $320,000 loan and about $2,023 a month in principal and interest.

Property tax: $400,000 of taxable value at 19.9878 mills is about $7,995 a year, or roughly $666 a month [2]
HO-6 insurance: $1,369 a year, or roughly $114 a month [3]
Association assessment: $835 a month [4]
Non-mortgage subtotal: about $1,615 a month
Total monthly outlay: about $3,638, of which about 44 percent is not principal and interest

A homestead exemption would reduce the tax figure for an owner who qualifies and applies, and a second-home or investment buyer gets none. The Property Appraiser's tax estimator will run the calculation at your purchase price and your municipality.

Now add a hypothetical special assessment of $30,000 collected over five years. That is $500 a month. Principal and interest do not move. The non-mortgage stack goes to roughly $2,115 and crosses 51 percent of the total. The building has quietly become the larger half of the payment.

Why payment-only affordability math understates the cost

Single-family carrying cost is mostly a function of loan size, and taxes and insurance scale with value fairly predictably. Condo carrying cost does not. Two units at the same price in the same submarket can differ by several hundred dollars a month depending on the age of the structure, the reserve study, the master policy deductible, and the assessment history.

That is also why price alone is a poor screen. Miami-Dade condo inventory sat at about 12 months of supply in July 2026, a buyer's market by the standard measure [1]. Some of that inventory is priced the way it is precisely because the carrying cost behind it is high. A unit that looks discounted per square foot can be the more expensive unit to hold once the assessment schedule is in view, a pattern visible across submarkets including the high-rise inventory in Brickell.

What an underwriter actually counts

Lenders do not qualify you on principal and interest. Fannie Mae's Selling Guide defines monthly housing expense, commonly called PITIA, to include principal and interest; property, flood, and mortgage insurance premiums as applicable; real estate taxes; ground rent; special assessments; any owners' association dues, including utility charges attributable to common areas; any monthly co-op corporation fee; and any subordinate financing payments on the subject property [6].

Three consequences follow.

First, the association fee reduces your borrowing capacity dollar for dollar within the housing expense and debt-to-income calculation. Every $100 of monthly dues is $100 that cannot go to principal and interest.

Second, an active special assessment counts. A buyer who assumes a seller-paid payoff at closing solves the cash problem, not the qualification problem, if collections continue.

Third, the building itself gets reviewed separately from the borrower. Fannie Mae requires a project review in addition to borrower and appraisal underwriting, covering project eligibility, property eligibility, and the priority of common expense assessments [7]. An association with unaddressed critical repairs or an unresolved funding gap can affect financing availability for every unit in it, regardless of how strong the individual borrower is.

How to underwrite a building before you write an offer

Request and read the current adopted budget with its reserve schedule, the structural integrity reserve study, the milestone inspection report and its status, a year or two of board meeting minutes, any approved special assessment schedule, and the master policy declarations page with the wind deductible. Then run the tax estimate at your purchase price rather than the seller's, and get an HO-6 quote for the specific unit rather than a county average.

If you are weighing specific buildings, a buyer consultation is where that document review happens before an offer. If you own a unit and want to know how its assessment history is affecting what it will bring, start with a listing valuation.

Frequently asked questions

Does the association fee include property taxes or HO-6 insurance?

No. The assessment funds the association's operating budget and reserves, including the master policy on the building. Your property tax bill and your HO-6 policy are separate obligations billed directly to you. Read the budget to confirm what a given fee covers, because inclusions such as unit utilities or internet vary by building.

Will a lender count a special assessment against my debt-to-income ratio?

Special assessments are named in Fannie Mae's definition of monthly housing expense [6]. If an assessment is being collected monthly during the term you are qualifying under, expect it to be included. Ask your loan officer how they will treat a specific assessment schedule, and get that answer before you go under contract rather than during underwriting.

Why is my property tax higher than what the seller pays?

Florida's assessment caps limit annual increases in assessed value for an existing owner, and those caps generally reset when ownership changes. A long-held unit can carry an assessed value well below market, which makes the seller's bill an unreliable estimate of yours. Run the Miami-Dade Property Appraiser's estimator at your contract price and your municipality's millage [2].

Do carrying costs vary by area within Miami-Dade?

Yes, on two axes. Millage is set municipality by municipality, so the same taxable value draws a different tax rate across Miami-Dade [2]. Insurance and reserve funding vary with structure age, construction type, height, and wind exposure. A coastal high-rise built in the 1980s and an inland mid-rise built in 2018 can price very differently on the non-mortgage lines at the same purchase price.

Does a lower purchase price always mean a lower monthly cost?

No. A lower price reduces principal and interest and reduces the tax base, but it does not reduce the association assessment, and it does not reduce a special assessment, which is typically allocated by percentage of ownership rather than by unit value. In buildings with large funding obligations, the discount in the price is often the market pricing the assessment in advance.
