Frequently Asked Questions

Q: What income do I need for a $400,000 house?

At 20% down, 7%, 30-year term, monthly payment is ~$2,129. To stay under 28% of gross income, you need at least $7,600/month ($91,200/year). With existing debts factored in, $100,000+ income is typically needed.

Q: How much should I save for a down payment?

Aim for 20% to avoid PMI. FHA loans accept 3.5% down with 580+ credit score. Always add 2%–5% of purchase price for closing costs and keep 3–6 months of mortgage payments in emergency savings.

Q: Does buying always beat renting?

Not always. Buying makes sense if you plan to stay 5–7+ years, have stable income, and a solid down payment. In very high-cost markets, renting and investing the difference can sometimes be the better financial outcome.

Q: What credit score do I need to buy a house?

Conventional loans require 620 minimum. Best rates with 740+. FHA accepts 580 (3.5% down) or 500 (10% down). VA loans have no official minimum. Higher credit score = lower rate = tens of thousands saved over 30 years.

Q: How long does the home buying process take?

Typically 3–6 months from starting search to closing. Pre-approval: 1–3 days. Finding and making an accepted offer: 1–3 months. Closing after acceptance: 30–60 days. Getting pre-approved first speeds up the entire process.
