How much down payment do I need for a $500K home?

The minimum down payment depends on your loan type. Conventional loans typically require 3-5% ($15,000 to $25,000), FHA loans require 3.5% ($17,500), and VA/USDA loans may allow 0% down. To avoid PMI entirely, you need 20% down ($100,000).

What is PMI and when can I remove it on a $500K home?

Private Mortgage Insurance (PMI) is required when your down payment is less than 20%. On a $500K home with 3% down, PMI costs approximately $283/month. You can request PMI removal once you reach 20% equity ($100,000 in home equity), and your lender must automatically cancel it at 22% equity.

Is it better to put 20% down on a $500K home or invest the difference?

Putting 20% down ($100,000) eliminates PMI and lowers your monthly payment significantly. However, if your investment returns exceed your mortgage rate after tax, keeping a smaller down payment and investing could yield higher net returns. Consider your risk tolerance, emergency fund needs, and the guaranteed savings from PMI elimination when making this decision.

How to Save for a Down Payment Faster

Set a target date: For a $500K home with 20% down, you need $100,000. Divide by months to get your savings goal.
Automate savings: Set up automatic transfers to a dedicated high-yield savings account.
Look into DPA programs: Many states offer down payment assistance for first-time buyers, grants, or forgivable second mortgages.
Consider gift funds: Conventional and FHA loans allow down payment gifts from family members with proper documentation.
Start with less: A 3% down payment ($15,000) lets you buy sooner, then refinance to remove PMI once you build equity.

How Down Payment Affects Your Interest Rate

Lenders view larger down payments as lower risk, which can translate to a better interest rate. Borrowers putting 20%+ down on a $500K home typically qualify for rates 0.125% to 0.25% lower than those with minimal down payments. On a $400,000 loan, even a 0.25% rate reduction saves $67/month.
