How to Save for a Down Payment Faster

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 $600K home typically qualify for rates 0.125% to 0.25% lower than those with minimal down payments. On a $480,000 loan, even a 0.25% rate reduction saves $80/month.

Frequently Asked Questions

How much down payment do I need for a $600K home?

The minimum down payment depends on your loan type. Conventional loans typically require 3-5% ($18,000 to $30,000), FHA loans require 3.5% ($21,000), and VA/USDA loans may allow 0% down. To avoid PMI entirely, you need 20% down ($120,000).

What is PMI and when can I remove it on a $600K home?

Private Mortgage Insurance (PMI) is required when your down payment is less than 20%. On a $600K home with 3% down, PMI costs approximately $340/month. You can request PMI removal once you reach 20% equity ($120,000 in home equity), and your lender must automatically cancel it at 22% equity.

Is it better to put 20% down on a $600K home or invest the difference?

Putting 20% down ($120,000) 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.
