Buyer reality check

Listings show a payment. Ownership shows a stack of bills. Mortgage principal and interest are only the start.

HOA dues fund the building budget today. They can rise when insurance renews, labor costs move, or the board finally funds a roof line that was deferred.

Reserve studies describe future capital work. Thin reserves do not mean repairs wait forever. They often mean a special assessment or a sharp dues increase instead.

Property tax on a listing may reflect the seller's old assessment. Many buyers see a higher bill after purchase when the unit is reassessed at or near sale price.

HO-6 insurance sits beside the master policy. Gaps between the two show up after water leaks, smoke damage, or a master deductible event.

Our calculators use your inputs only. They are planning tools, not quotes from a lender, insurer, or association.

Educational overview only. Verify tax, insurance, and HOA figures with official documents and licensed professionals before you commit to a purchase.

What to ask before you offer

  • Request the current HOA budget, reserve study, and two years of board minutes for the specific building.
  • Obtain master insurance declarations and ask how the last renewal changed premiums or deductibles.
  • Model property tax on your expected purchase price, not the seller's bill.
  • Read special assessment votes and engineering reports referenced in recent packets.
  • Confirm owner-occupancy and rental rules if your loan program requires them.
  • Compare two buildings at the same price with different dues and reserve profiles.

Run the numbers

Use your own assumptions in these free tools. None of them pull live HOA budgets, tax rolls, or insurance quotes from external databases.

How this calculator works

This free condo calculator adds mortgage principal and interest, HOA dues, property taxes, HO-6 insurance, PMI when applicable, special assessment risk, and other ownership costs. Run the numbers before you tour or make an offer.

For a line-by-line budget with utilities and an assessment buffer, use the condo expenses calculator. Read how the expenses calculator works, condo fees vs HOA fees, and monthly cost breakdown.

Enter purchase price, down payment, interest rate, loan term, property tax rate, monthly HOA dues, and insurance premium. To stress-test a lump-sum or spread special assessment, use the special assessment calculator.

What to check before buying a condo

  • Current HOA budget, reserve study, and percent funded, not just the monthly dues on the listing
  • Master insurance policy terms, deductibles, and whether wind, flood, or earthquake coverage is included or billed separately
  • Pending special assessments, milestone inspection findings, and capital projects in meeting minutes
  • Property tax reassessment rules in your state and county after purchase
  • Lender condo questionnaire requirements, owner-occupancy limits, and debt-to-income with HOA
  • Your HO-6 quote aligned to the master policy's walls-in vs bare-walls coverage

Common hidden condo costs

  • HOA dues that rise when master insurance renews or reserves are replenished
  • Special assessments for roofs, facades, plumbing, or compliance work
  • PMI when your down payment is below 20%
  • Interior maintenance, appliances, and unit-level repairs not covered by the association
  • Separate flood or earthquake policies where required
  • Move-in fees, transfer fees, and higher property taxes after reassessment at sale

July 2026: what changed for condo buyers

Fannie Mae Lender Letter LL-2026-03 made the $50,000 per-unit master policy deductible cap mandatory on July 1, 2026, and sunsets Limited Review on August 3. Read our Fannie Mae condo lending summary and verify master declarations on any building you finance.

Freddie Mac's July 2 Primary Mortgage Market Survey put the 30-year fixed at 6.43%—a seven-week low. Association dues and HO-6 premiums do not move with PMMS; model both in the calculator above. Mortgage rate take for condo payments.

Two buildings, same list price

Placeholder math for planning—substitute your estoppel and assessor quotes. Building A: $400,000 purchase, 10% down, 6.75% for 30 years, $620 HOA, 1.1% property tax, $120/month HO-6 → roughly $3,441/month before PMI or assessments. Building B at the same price with $890 HOA adds about $270/month because the master policy renewed higher.

When to use this calculator

  • You are setting a search price range before touring buildings
  • A lender pre-approval shows a max loan but not your comfortable all-in payment
  • You want one number that includes mortgage, HOA, tax, and insurance together

Inputs you need

  • Purchase price or target range
  • Down payment amount or percent
  • Interest rate and loan term
  • Monthly HOA dues from the listing or resale packet
  • Property tax rate or estimated annual bill
  • Monthly HO-6 insurance estimate

How to interpret the result

  • Compare the total monthly payment to your net take-home pay, not just the lender's maximum
  • If the payment leaves little room for dues increases, treat the unit as over budget even if you qualify
  • Run a second scenario with higher HOA or tax to see how fast the payment becomes uncomfortable

What this calculator does not know

  • Live tax bills, insurance quotes, or HOA budgets from any database
  • Lender approval, HOA questionnaire results, or project eligibility
  • Future HOA increases unless you change the inputs yourself
  • Closing costs and cash due at settlement
  • Special assessments unless you model them separately
  • Income tax deductions for mortgage interest or property tax

Documents to verify before relying on the estimate

  • HOA budget and most recent financial statements
  • Reserve study and percent-funded summary
  • Master insurance declarations and renewal summary
  • County property tax estimate for the unit at your offer price
  • HO-6 insurance quote matched to master policy coverage

Educational estimates only. Confirm figures with association documents, county tax offices, and licensed professionals before you make an offer.

Frequently asked questions

Does the lender count HOA in my payment?
Most lenders include HOA in qualifying ratios. This tool helps you see the full picture with taxes and insurance too, not just what fits on paper.
How much condo can I afford?
Model purchase price, down payment, rate, HOA, tax, and insurance here. Your affordable payment should leave room for reserves and fee increases—not just match pre-approval.
What is a condo affordability calculator?
A tool that estimates all-in monthly housing cost for a condo. The homepage condo cost estimator is our primary affordability calculator.

Frequently asked questions

What should I model besides the mortgage payment?
Add HOA dues, property tax, HO-6 insurance, PMI if applicable, utilities, and a buffer for assessments. Listings rarely show that full stack.
Are calculator results a quote from my lender or insurer?
No. They reflect the numbers you enter. Verify tax, insurance, and HOA figures with official documents before you rely on them for an offer.
How much does a condo cost per month?
A condo's monthly cost usually includes mortgage principal and interest, property taxes, HOA dues, and HO-6 insurance. Many buyers also budget for utilities, interior maintenance, PMI when the down payment is under 20%, and a buffer for special assessments. Use the calculator above with your own purchase price, rate, HOA, and tax assumptions to see a total monthly payment.
What is a condo calculator?
A condo calculator estimates your full monthly housing payment, not just the mortgage. True Condo Cost adds HOA fees, property taxes, and insurance so you can compare listings on equal terms before you tour or make an offer.
Are condo fees the same as HOA fees?
In most condominium associations, yes. Buyers and listing agents use both terms for the same monthly association dues. The fee is separate from your mortgage, property tax, and HO-6 insurance. See our condo fees vs HOA fees guide for cases where the terms differ, such as co-ops or special assessments.
How do I estimate condo HOA fees before buying?
Request the current HOA budget and resale certificate from the seller or listing agent. Do not rely on an old listing figure. Enter the monthly dues in the calculator above, then stress-test a 10% to 20% increase if the building has weak reserves or rising insurance costs.
What is a condo cost estimator?
A condo cost estimator combines mortgage math with ownership costs that listings often omit: HOA dues, taxes, insurance, and optional buffers for maintenance or assessments. Our free tool updates as you change inputs so you can model different buildings side by side.

Sources to verify before buying

Use this checklist during due diligence. Calculators help you plan; these documents tell you what a specific building actually costs.

  • HOA budget and audited financials (or reviewed statements if the association is small)
  • Reserve study with percent-funded and component schedules — often prepared under CAI / APRA standards
  • Master insurance declarations: carrier, deductible, wind/hail sublimits, and coinsurance
  • Board minutes covering the last two insurance renewals and any assessment votes
  • Written special assessment notices and payment plans
  • County assessor or municipal property tax estimator for the parcel (not a neighbor’s bill)
  • HO-6 quote aligned to master policy gaps — confirm with your state Department of Insurance licensed agent
  • Lender condo questionnaire or Fannie Mae / Freddie Mac project review status for warrantability
