At 8% annual returns, investing the $280,000 down payment produces $969,420 more net wealth over 20 years than using it for a down payment — even after paying $514,361 in extra interest and 15% capital gains tax on liquidation.

Should I put 20% down or invest the money instead?
If you can access 0% down financing (like a VA loan with no PMI), investing the down payment in a diversified portfolio averaging 7-10% annually can build significantly more wealth than the interest savings from a smaller mortgage — especially over 10+ years.
Best for: VA-eligible buyers, financially disciplined investors willing to carry a larger mortgage in exchange for portfolio growth
How It Works
Understanding the Invest vs. Down Payment Calculator
This calculator models two wealth-building paths side by side: Path A (traditional 20% down, smaller mortgage, no investment) vs. Path B (0% down VA loan, invest the capital, larger mortgage). It tracks equity buildup, portfolio growth, mortgage balances, and net wealth year by year.
Worked example: Home price: $600,000. Path A: 20% down ($120,000), conventional at 6.50%, monthly P&I: $3,035. Path B: VA loan at 6.75%, 0% down, $120,000 invested averaging 8% annually. VA funding fee of 2.15% ($12,900) is financed. Monthly P&I: $3,980 — $945 more per month. After 10 years, Path A equity: $192,000. Path B equity: $87,000 — but the investment portfolio has grown to $259,000 (pre-tax). Path B net wealth: $346,000 vs. Path A: $192,000. Path B is ahead by $154,000.
The calculator includes Advanced Settings for capital gains tax, property appreciation, and monthly investment contributions. The chart visualizes the crossover point where Path B overtakes Path A.

About This Calculator
What the Invest vs. Down Payment Calculator is For
Most buyers default to 'put as much down as possible.' But for VA-eligible buyers with investable capital, 0% down can be the mathematically superior choice. This calculator models both paths year by year: Path A puts your down payment into home equity; Path B deploys it into a diversified portfolio while financing the full purchase through VA. The chart shows net-wealth divergence over your chosen horizon, accounting for the VA funding fee (financed), the higher monthly payment, capital gains tax on investment liquidation, and the equity buildup difference. Adjust expected returns, tax rates, and time horizon to stress-test the arbitrage.
Common Use Cases
- VA-eligible buyers deciding between 0% down and traditional financing
- Physicians and high-earners modeling opportunity cost of home equity
- Wealth managers evaluating down payment arbitrage for veteran clients

A Navy veteran and orthopedic surgeon relocating to Ashland, Oregon for a position at Asante Rogue Regional worked with her wealth management advisor and Lumen Mortgage to finance a $1,400,000 home with zero down — deploying the $280,000 she would have put into home equity into a diversified portfolio instead.

An IRA loan uses your retirement balance — divided by 36 months — as qualifying income. No distributions required, no age restrictions. Here are two real Oregon scenarios where this program closed the gap: a newly retired Tigard couple buying without triggering taxable distributions, and a recently self-employed Oregon City borrower qualifying without two years of returns.
