💬 18 Frequently Asked Questions (FAQs)

1. What is a down payment?
A down payment is the portion of the home price you pay upfront, reducing the amount you need to borrow.

2. How much should I put down on a house?
While 20% is ideal to avoid mortgage insurance, many loans allow 3–10% down with added insurance costs.

3. What happens if I put less than 20% down?
You’ll likely need to pay mortgage insurance, which increases your monthly payment until you reach 20% equity.

4. What is mortgage insurance?
Mortgage insurance protects the lender if you default on the loan. It’s usually required for down payments under 20%.

5. How accurate is this calculator?
It uses industry-standard formulas to estimate your costs. Real-life figures may vary slightly based on lender fees, taxes, and insurance.

It lowers your loan amount, reduces monthly payments, avoids mortgage insurance, and saves interest over time.
