Owning a Miami condo. Know the full cost.

The purchase budget covers deposits, cash due at closing, financing charges, applicable developer fees, initial association contributions and any furnishing or finishing work. The ownership budget covers recurring expenses after closing. Keeping these separate helps you compare a cash purchase with a financed purchase without counting the same deposit twice.

For ongoing costs, use this framework: loan payment + property taxes + unit insurance + association dues + other recurring expenses. Then set aside liquidity for irregular bills, maintenance and assessments. The loan’s principal portion builds equity; it is still money leaving your account each month.

A seller’s current tax bill may reflect exemptions or an assessment cap that does not transfer to you. For a new building, a bill based on an earlier construction stage may also be a poor guide to the completed residence. Use the county estimator with the proposed purchase details and confirm the assumptions with a qualified adviser.

The 1.9% used in our calculator is a planning assumption, not a verified Miami-Dade tax rate for every condo. At a hypothetical $1 million price, it produces $19,000 a year, or $1,583.33 a month. Actual taxes depend on taxable value, applicable millage, exemptions and other assessments. Run the Miami-Dade tax estimate ↗

Ask a licensed insurance professional to coordinate your unit coverage with the association’s master policy. Compare covered property, exclusions, deductibles, liability, loss assessment and any separate flood or wind coverage. Do not add the association’s full building premium again if it is already funded through dues.

OIR averages below include wind, as of March 31, 2026. They are not luxury-project quotes. Your insurer, coverage and deductible affect the premium.

A lower monthly fee is useful only after you understand what it pays for. Request the current operating budget, the unit’s allocated assessment, reserve funding, insurance information, any shared-facility obligations and separately billed services. Check whether quoted dues include parking, utilities or other items you would otherwise pay yourself.

HOA dues are usually paid separately from the mortgage-servicer payment. CFPB explanation ↗ For developer sales, review the estimated budget and schedule of unit-owner expenses in the offering documents. Florida disclosure requirements ↗

Also request applicable inspection and reserve-study information. DBPR describes reserves as funding for future repairs and replacement. A new building still needs a long-term funding plan; older buildings require property-specific review rather than an assumption that every one has the same assessment exposure.

This example assumes a $1 million purchase, 30% down, a $700,000 fixed-rate loan at an illustrative 7% for 30 years, taxes at the planning assumption of 1.9%, and assumed dues of $1,500 a month. Unit insurance uses the $2,801 Miami-Dade annual benchmark above only as a placeholder. These inputs are not an available listing, current loan offer or property-specific expense quote.

Without the loan, the three modeled expenses still total $3,316.75 a month, or $39,801 a year. That excludes utilities not covered by dues, maintenance, separate coverage, optional services, assessments, furnishing, transaction costs and taxes connected with income or a future sale. Cash also has an opportunity cost; this is a cash-outflow illustration, not a complete investment-return calculation.

Small changes matter: an extra $500 in monthly dues adds $6,000 a year. Raising the illustrative tax assumption from 1.9% to 2.0% adds $1,000 a year on a $1 million base. An additional $1,200 annual insurance premium adds $100 a month.

1. Run the tax estimate for the actual address and purchase assumptions.
2. Obtain an insurance quote coordinated with the master policy.
3. Read the unit’s dues allocation, current budget and reserve information.
4. Ask about approved or proposed assessments and association borrowing.
5. Have your lender show financing costs and cash to close; do not treat an early preapproval as a final condo approval.

Use the mortgage calculator to change the assumptions. Its $1,200 insurance default is editable and is not the regulator’s county average. Comparing timelines too? Read pre-construction versus move-in-ready condos.
