Starting with zero equity creates real risks in the early years. A market dip of just 5-10% can put you underwater.

How to Use This Zero Down Payment Calculator

This calculator identifies every $0 down mortgage program you may qualify for based on your military status, location, profession, and income — then compares monthly payments and total costs so you can choose the best option.

Quick Results

Enter your Home Price, Annual Income, and Interest Rate, then select your military status, location type, profession, and whether you are a first-time buyer. The calculator instantly shows which programs you qualify for, estimated monthly payments, and how zero down compares to 3.5%, 5%, and 20% down payments.

Advanced: Program Comparison Tab

The Program Comparison tab shows a full cost table — rate, upfront fee, annual fee, and monthly total — for all four zero-down programs side by side. The True Cost of Zero Down tab quantifies exactly how much more you pay over 30 years compared to putting money down. The Qualification Requirements tab lists the exact criteria for each program.

Pro: Long-Term and Wealth Analysis

The Long-Term Impact tab shows your equity buildup year by year and when you face negative equity risk. The Best Strategy tab compares zero down plus investing the would-be down payment against a conventional purchase with a down payment. The PMI/Fee Comparison tab shows the total lifetime cost of mortgage insurance for each program.

Zero Down Payment Formula

Loan Amount (Zero Down) = Home Price + Upfront Fee (VA/USDA/FHA)

Monthly P&I = Loan × [r(1+r)^n] / [(1+r)^n − 1]
where r = annual rate / 12, n = loan term in months

VA Funding Fee = Loan Amount × 2.15% (first use, 0% down)
USDA Upfront Fee = Loan Amount × 1.00%
USDA Annual Fee = Loan Amount × 0.35% / 12 per month
FHA MIP = Loan × 1.75% upfront + Loan × 0.85% / 12 monthly

Extra Monthly Cost = Monthly Payment (0% down) − Monthly Payment (20% down)

The VA funding fee is financed into the loan, so the actual loan balance for VA is slightly above the purchase price. USDA works the same way. This means your monthly payment is based on the purchase price plus the financed fee, not just the purchase price alone.

Example: Marcus Buys His First Home with Zero Down

Scenario: Army veteran buying a $320,000 home in San Antonio, TX

Home Price$320,000
ProgramVA Loan (veteran, 0% down)
VA Funding Fee (2.15%)$6,880 (financed in)
Effective Loan Amount$326,880
Interest Rate6.625%
Monthly P&I$2,093
Monthly PMI$0 (no PMI on VA loans)
vs. 20% Down + Conventional$1,634/mo (saves $459/mo but requires $64,000 down)
Equity After Year 3~$17,000 (5.3% of home value)
Underwater If Market FallsLess than 5% in first 2 years

Marcus chose the VA loan because he had no savings for a down payment but strong income and job stability. By year 5, his equity exceeded $35,000 — more than enough cushion against market volatility.

Frequently Asked Questions

Requirements vary by program: VA loans require 580-620 at most lenders (some go lower); USDA requires 640 for automated underwriting (lower with manual underwrite); NACA does not have a minimum credit score but reviews your full credit pattern; physician loans typically require 680-700. Higher scores get better rates across all programs. If your score is below the minimum, working on credit for 6-12 months before applying can significantly improve your rate.
No — each program has property restrictions. VA loans require the home to meet VA minimum property requirements (MPR) and must be your primary residence. USDA loans require a property in a USDA-eligible area (rural/suburban fringe) — use the USDA map to verify. NACA is primarily for urban and suburban areas. Physician loans are more flexible but typically require primary residence use and may exclude condos or investment properties. All programs require a home appraisal.
Yes — the NACA (Neighborhood Assistance Corporation of America) program offers zero down payment, no closing costs, no fees, no PMI, and rates often 1-2% below market. The tradeoff is an extensive qualification process: multiple counseling sessions, detailed budget review, and a waiting period. NACA prioritizes low-to-moderate income buyers and first-time buyers. Processing time is longer than conventional lending — typically 3-6 months. But for eligible buyers, the lifetime savings can be substantial.
Zero down means a larger loan, which means a higher monthly payment, which means a higher DTI ratio. For example, on a $350,000 home at 6.75%: 0% down = $2,270/mo P&I; 10% down = $2,043/mo P&I — a $227 difference. If your qualifying income is $7,000/month and your DTI limit is 43%, 0% down = 32.4% housing DTI vs 10% down = 29.2%. Physician loans help by excluding student loan debt from the DTI calculation, which is a major advantage for new doctors.
With zero down, you have no equity cushion. If your $300,000 home drops 5% to $285,000 in the first year, you owe more than the home is worth — called being "underwater" or having negative equity. This is not a problem if you plan to stay long-term and can afford your payments, but it prevents selling or refinancing without a loss. By year 3-5, normal mortgage payments build enough equity that a modest market dip no longer puts you underwater. VA loans have the advantage that you cannot lose your zero-down benefit if values drop.
