Frequently Asked Questions

What is included in a monthly mortgage payment?

Your monthly mortgage payment typically includes four main components (PITI): Principal (the loan amount), Interest (the cost of borrowing), Property Taxes (usually 0.69-1% of home value annually in WA/ID), and Insurance (homeowners insurance). If your down payment is less than 20%, you'll also pay PMI (Private Mortgage Insurance). Some properties also have HOA fees.

How much down payment do I need?

Down payment requirements vary by loan type: Conventional loans can require as little as 3% down, FHA loans require 3.5%, VA loans require 0% for eligible veterans, and USDA loans require 0% for rural properties. Our 1% Home Program allows you to buy with just 1% down, with Q Home Loans providing a 2% grant (up to $4,500). Putting 20% down eliminates PMI and typically gets you better interest rates.

What credit score do I need to buy a home?

Minimum credit scores vary by loan type: Conventional loans typically require 620+, FHA loans accept scores as low as 580 (or 500 with 10% down), VA loans don't have a strict minimum but most lenders prefer 620+, and USDA loans typically require 640+. Higher credit scores (740+) qualify for the best interest rates, potentially saving you tens of thousands over the life of your loan.

Should I choose a 15-year or 30-year mortgage?

30-year mortgages offer lower monthly payments and more flexibility in your budget, making them ideal for first-time buyers or those who want to invest extra cash elsewhere. 15-year mortgages have higher monthly payments but significantly lower interest rates (typically 0.5-1% less) and you'll save $100,000+ in interest over the loan term. Use our Comparison Calculator to see the exact difference for your situation.

What are current mortgage rates in Washington and Idaho?

Mortgage rates change daily based on market conditions. As of 2025, rates typically range from 6-7% for conventional loans.

How accurate is this mortgage calculator?

This calculator provides accurate estimates based on the information you enter. However, your actual mortgage payment may vary based on factors like exact property taxes (which vary by county in Washington and Idaho), actual insurance costs, HOA fees, and the specific loan program you choose. For a precise quote tailored to your situation, get pre-approved with Marcus Vogt. Pre-approval gives you an exact payment amount and shows sellers you're a serious buyer.
