Condo Mortgage Calculator
Calculate your complete condo monthly payment including HOA fees, HO-6 insurance, and any non-warrantable rate premiums. See how HOA fees impact your buying power, whether your condo qualifies for FHA or VA financing, and how to evaluate HOA financial health before you buy.
A condo is "warrantable" if it meets Fannie Mae/Freddie Mac standards — qualifying for standard conventional, FHA, and VA financing. Failing any criterion makes it "non-warrantable," limiting financing to portfolio lenders at higher rates.

HOA fees count in your DTI just like a debt payment. Your $350/month HOA consumes 4.1% of your DTI capacity — reducing your maximum home price by approximately $53,963.

|---|---|---|---|
| $100/mo | 1.2% | $15,418 | -$17,131 |

How to Use This Condo Mortgage Calculator
This calculator handles condo-specific mortgage complexities that a standard mortgage calculator ignores — warrantability status, HOA fee impact on DTI, HO-6 insurance, and non-warrantable rate premiums. It gives you the true total monthly cost of condo ownership.
Quick Results
Enter your Condo Price, Down Payment, Interest Rate, and Monthly HOA Fee. Select Warrantable or Non-Warrantable — the calculator automatically applies a 0.5% rate premium for non-warrantable condos (range is 0.25-1.0% in practice). Add your Annual HO-6 Insurance, property tax, and income to see total PITI + HOA cost and your complete DTI.
Advanced: Warrantability, HOA Health, FHA vs Conventional
The Warrantable vs Non-Warrantable tab flags which of the seven warrantability criteria your condo may fail based on your inputs, with a complete side-by-side comparison of financing terms. The HOA Financial Review tab evaluates reserve fund adequacy, delinquency rates, and investor concentration against lender standards. The FHA vs Conventional tab explains what additional approvals are needed for FHA and VA financing on a condo.
Pro: HOA Impact, Assessment Risk, Complete Insurance Guide
The HOA Fee Impact tab quantifies exactly how much each $100 in HOA fees reduces your maximum loan amount and home price. The Assessment Risk tab profiles special assessment risk by building age and common capital expenditure categories with typical per-unit costs. The Insurance tab explains the split between the HOA master policy and your required HO-6 policy, including the often-overlooked loss assessment coverage.
Condo Mortgage Payment Formula
P&I = Loan Amount × [r(1+r)^n] / [(1+r)^n − 1]
where r = effective rate / 12, n = 360 months (30yr)
Non-Warrantable Effective Rate = Base Rate + 0.25% to 1.0% premium
DTI = (Total Monthly Housing Cost + Other Monthly Debts) / Gross Monthly Income × 100
HOA Impact on Max Loan = HOA Fee × [(1+r)^n − 1] / [r(1+r)^n]
(Every $1 in monthly HOA obligation reduces max loan by approx. $150-$165 at current rates)
HOA Impact on Max Home Price = HOA Impact on Max Loan / (1 − Down Payment %)
The HOA impact formula reverses the standard mortgage payment formula to convert a monthly payment into a loan amount equivalent. A $350/month HOA fee has the same DTI impact as roughly a $50,000-$55,000 additional loan at today's rates — that is how much less home you can buy because of HOA fees.
Example: Jennifer Buys a Downtown Condo
Scenario: $410,000 warrantable condo, 15% down, $450 HOA fee
| Purchase Price | $410,000 |
| Down Payment (15%) | $61,500 |
| Loan Amount | $348,500 |
| Interest Rate (warrantable) | 7.0% |
| Monthly P&I | $2,319 |
| Property Tax (1.0% annual) | $342/mo |
| HOA Master Policy (via HOA) | Included in HOA fee |
| HOA Monthly Fee | $450/mo |
| HO-6 Insurance (annual $750) | $63/mo |
| PMI (85% LTV) | $174/mo (0.6% annual) |
| Total PITI + HOA + HO-6 + PMI | $3,348/mo |
| Gross Monthly Income Required (36% DTI) | $9,300/mo ($111,600/yr) |
Jennifer earns $10,500/month — her DTI is 31.9%, comfortably within limits. She notes that if she bought a comparable house without an HOA, she could afford a $445,000+ home. The $450/month HOA effectively reduces her buying power by about $62,000.
