Frequently Asked Questions
What is the minimum credit score to buy a house?
Most conventional loans require a minimum FICO score of 620. However, government-backed FHA loans can be approved with scores as low as 580 (with a 3.5% down payment) or even 500 (with a 10% down payment). Generally, a score of 740 or higher will secure the best interest rates.
How much down payment do I really need?
You do not need 20% down. Many first-time buyers qualify for conventional loans with as little as 3% down. FHA loans require 3.5% down. VA loans and USDA loans allow for 0% down. Keep in mind that a down payment of less than 20% will typically require Private Mortgage Insurance (PMI).
Does getting pre-approved hurt my credit score?
Yes, but only slightly. Getting pre-approved involves a "hard pull" on your credit, which usually lowers your score by 2 to 5 points. However, if you shop around with multiple lenders within a 14 to 45-day window, credit bureaus treat all those mortgage inquiries as a single event, so the impact is minimized.
Should I pay off my mortgage early or invest?
This is primarily a math equation based on your interest rate. If your mortgage rate is low (e.g., 3-4%), historical stock market returns (averaging 7-10%) usually yield higher wealth over the long term. If your mortgage rate is high (e.g., 7-8%), paying off your mortgage early provides a guaranteed, risk-free 7-8% return on your money.
