Real-time interactive calculator built for the Las Cruces, NM market. Enter your income, debts, and down payment. We'll show you the home price you can realistically buy, plus your monthly PITI breakdown, plus three lender DTI scenarios.
This calculator uses the same DTI (debt-to-income) ratio approach Las Cruces lenders use to pre-approve buyers. We solve for the maximum home price where your monthly PITI plus other debts stays within the DTI ceiling you select.
PITI stands for Principal, Interest, Taxes, and Insurance, plus PMI/MIP and HOA where applicable. We calculate principal and interest using a standard 30-year amortization at the rate you enter, then add property taxes (using the Doña Ana County effective rate of 0.74%), homeowners insurance, HOA, and PMI (estimated at 0.5% of loan amount annually for conventional loans below 20% down, or 0.85% MIP for FHA).
TipsHakes Brothers, French Brothers, KT Homes, and others are running rate buy-downs as low as 5.49% on inventory homes in 2026. That can boost your affordability by $30K-$50K vs the open-market rate.
New Mexico caps annual residential assessment increases at 3% per year for owner-occupied. Your taxes stay predictable as values rise.
If you're VA-eligible, your real affordability is meaningfully higher than the calculator's standard assumptions. Talk to Gilbert Patino.
With a 6.5% mortgage rate and 31% front-end DTI, a household earning $75,000/year with $400 in monthly debts and $20,000 down can typically buy around $300K-$325K in Las Cruces. Use the calculator above for a personalized number.
Conventional lenders typically allow 28-31% front-end DTI and 43-45% back-end. FHA allows 31% / 43% standard with exceptions to 50% for strong compensating factors. VA uses a residual income method instead of strict DTI caps.
Conventional 3% down (5% more typical), FHA 3.5%, VA 0% for eligible vets, USDA 0% for rural Doña Ana County properties. 20% down avoids PMI but is not required.
PITI: principal, interest, property tax (county effective rate ~0.74%), and homeowners insurance. Plus PMI if <20% down on conventional, plus HOA where applicable, plus FHA MIP for FHA loans.
