What You Need Upfront
Beyond your down payment, you'll need significant cash at closing. Here's the complete breakdown:
Down Payment (20%)
$100K
Closing Costs (2-5%)
$12-31K
Moving & Setup
$5-15K
Immediate Repairs
$10-30K
Total Cash Needed: $127K – $201K
Plus a 3-6 month emergency fund after closing. Don't deplete your savings completely for the down payment.
Can You Actually Afford It?
Banks will approve you based on income alone. But you should check every box before buying:
✓
Your household income is $175K+ annually (comfortably, not stretching)
✓
You'll have 6-12 months emergency fund after your down payment
✓
Your total debt payments stay under 36% of gross income
✓
You're still maxing out retirement contributions (don't sacrifice your future)
✓
You're planning to stay in the home 7+ years minimum
✓
Your credit score is 740+ (every 20 points saves you thousands)
Can't Check Every Box?
That's okay. It doesn't mean you can't buy—it means you should wait, save more, or look at a lower price point. Your future self will thank you.

Frequently Asked Questions
What credit score do I need for a $500K mortgage?
▼
Minimum 620 for conventional loans, but aim for 740+ for the best rates. Every 20 points can save you 0.25% on your rate—that's $30K+ over 30 years. If you're at 680, spend a few months improving your score before applying.
Should I choose a 15-year or 30-year mortgage?
▼
15-year pros: Save $385K in interest, build equity faster, typically get 0.5% lower rate
15-year cons: Monthly payment is $1,167 higher ($4,494 vs $3,327), less financial flexibility
30-year pros: Lower payment means more cash flow, easier to qualify, more flexibility
30-year cons: Pay significantly more in interest over time
Smart move: Get a 30-year but pay extra toward principal when you can. You get flexibility with the option to save big.

Is PMI worth avoiding?
▼
PMI costs $200-400/month but lets you buy sooner with less down. Do the math: if home prices in your area are rising 5%/year, waiting to save 20% might cost you more than the PMI itself. Plus, PMI automatically drops off once you hit 20% equity.
How much will I actually pay in year 1?
▼
Expect $60K-75K total in your first year:
- Monthly payments (P&I + taxes + insurance): $48K
- Maintenance and repairs: $6-15K
- Higher utilities vs renting: $3-5K
- Furniture and setup: $5-10K
- PMI (if applicable): $3.6K
What's the minimum income I need?
▼
Using the 28/36 rule (housing costs ≤28% of gross income, total debt ≤36%):
Absolute minimum: $150K household income with no other debts
Comfortable: $175K+ household income
Ideal: $200K+ household income
Remember: just because you qualify doesn't mean you should buy at that price point. Leave room for life, savings, and emergencies.

How much are closing costs really?

Expect 2-5% of the purchase price, or $12,500-31,250 on a $500K mortgage. This includes:
- Origination fees: $2,500-5,000

- Recording fees: $200-500
