Affordability Scenario

Can I Afford a $400,000 House?

The monthly payment is only part of the picture. Here's what $400k actually costs and what income you need to qualify.

Quick answer: $400k is a stretch on $80k/year

At $80k gross income, the 28% rule puts your safe monthly payment at $1,867. A $400k home with 10% down costs roughly $2,720/month - that's 41% of gross income. Most lenders will flag this. If your income is $100k+ or you have minimal debt, it may still work. Run your exact numbers below.

What does $400k actually mean for your budget?

The 28% Rule

Lenders use the 28% rule as the ceiling for housing costs. Here's what that means by salary:

  • $70k/year$1,633/mo max ✗
  • $80k/year$1,867/mo max ⚠
  • $100k/year$2,333/mo max ✓
  • $120k/year$2,800/mo max ✓

A $400k home with 10% down = ~$2,720/month

True Upfront Cost

The down payment is just the beginning. Here's what you'll need in cash before closing on a $400k home:

  • Down payment (10%)$40,000
  • Closing costs (~3%)$12,000
  • Cash reserves (2mo)$5,400
  • Total needed~$57,000

With 20% down: ~$97,000 total upfront - but no PMI

How to Make It Work

If $400k feels like a stretch, these three levers move the number most:

  • 1. Increase down payment
    20% down eliminates PMI and saves $150–250/month
  • 2. Pay off existing debt
    Every $200/month in debt payments cuts your max home price by ~$40k
  • 3. Add a co-borrower
    A second income on the application can unlock significantly higher approval amounts
