Condo Mortgage Calculator 2026 — HOA Fee & Buying Power

The hidden cost of HOA fees

An HOA fee is not just a monthly bill — it directly reduces how much home you can buy. Lenders count the HOA fee as part of your housing payment when they check your debt-to-income ratio, so every dollar of HOA is a dollar that cannot go toward principal and interest. At a 6.5% rate over 30 years, a $450/month HOA fee supports about $71,200 of loan on its own. Put another way: with a $2,000/month total budget, a $450 HOA fee cuts your affordable price from about $280,000 to about $212,000 — roughly $68,000 of buying power gone before you even start.

Warrantable vs non-warrantable condos

Before you fall in love with a condo, check whether it is warrantable — meaning it meets Fannie Mae and Freddie Mac rules so a conventional lender can finance it. Non-warrantable condos can only be financed with specialty, portfolio, or cash deals, often at higher rates or larger down payments. Common reasons a condo becomes non-warrantable: a single investor owns more than 10% of units, more than 50% of units are investor-owned or rented, the HOA is involved in litigation, or the project is a condotel or has mandatory resort-style amenities.

HOA red flags lenders check

Worked example: $300,000 condo, $350/month HOA

10% down ($30,000), loan $270,000, 6.5% rate, 30-year term, 1.10% property tax, $1,800/year insurance. Monthly principal & interest = $1,706.58; property tax = $275.00; insurance = $150.00; HOA = $350.00; total = $2,481.58. The $350 HOA alone supports about $55,400 of loan — with the same $2,481.59 budget and no HOA, you could afford a condo worth about $353,000, roughly $53,000 more.

Questions to ask before buying a condo

Ask the HOA for: the current budget and reserve study, the last two years of meeting minutes, any planned special assessments, the rental/investor percentage, and whether litigation is pending. Ask your lender early whether the building is warrantable — finding out after your offer is accepted can cost you the deal and your earnest money.
