Can I Afford a $450,000 House?

$450,000 is the floor in many strong job markets. Requires real income to feel comfortable — and discipline to stay out of house-poor territory if rates wobble.

Estimates only. Not mortgage approval, not lender precision, not legal or tax advice.

Default verdict (you can edit any of this)

Manageable

Workable on $125k–$150k household income with modest other debt.

30 years at 7% with 10% down ($45k) puts P&I near $2,700/mo. Add ~$410 tax, $165 insurance, $190 PMI = ~$3,465/mo all-in. On $12,000 gross that's 29% — at the upper edge of 'Manageable'. 20% down ($90k) removes PMI, dropping to ~$3,275. Stretch the down to 25% and the math truly comfortably clears the 28% line.

Costs people forget

The line items that don’t show up on the loan estimate but absolutely show up in the bank account.

  • Rate sensitivity above $400k

    Each 0.5% APR move = ~$130/mo here. Locking the rate early matters more at this price point.

  • Property-tax stacking

    $5,000/yr (~1.1%) vs $10,000/yr (~2.2%) is the same house in different states. Run your local rate.

  • Closing costs: $9–$22k

    Lender, title, prepaid escrows, inspections. Mostly out-of-pocket.

  • PMI: ~$190/mo at 10% down

    Roughly $2,300/yr of pure premium until you hit 20% equity. The 20% down move erases it.

  • Repair sinking fund: $4,500/yr

    1% of home value is the rule of thumb. Skipping it means borrowing for the next surprise.

  • First-year setup

    Furniture, moving, window treatments, immediate cosmetic fixes — $10k–$20k is common.

Reality check before you bid

  • Aim for total housing ≤ 28% of gross; total DTI ≤ 36%. At $12,000 gross + $600 other debt, the math works just inside both lines.

  • $200/mo of HOA changes the verdict noticeably. Many $450k condos / townhomes carry $250-$500/mo HOAs.

  • Insurance has been rising fastest at this price tier in coastal / wildfire / hail markets.

  • Stretch beyond 35% housing ratio and the month becomes fragile to a single car-repair surprise.
