What Mortgage Can I Afford?

November 10, 2025

1) Start with your “comfortablepayment”

Forget the price tag at first. Pick the monthly number you can live withon your most expensive month (holidays, travel, kids’ sports). That becomesyour guardrail.

Math:

  • Add up monthly debts on your credit (car, cards, student loans).
  • Choose a comfort DTI (many buyers like ≤ 40%). Some will want lower if     monthly income is higher
  • Gross monthly income × DTI − current debts = target mortgage payment (including     taxes/insurance/HOA).

2) Price the whole payment (notjust the rate)

Build your budget with PITI:

  • Principal & Interest
  • Taxes
  • Insurance
        Plus: HOA/condo dues, mortgage insurance (if <20% down), utilities, and     a maintenance cushion (1–2% of price/year for a house).

3) Pick a loan structure that fitsyour timeline

(0 points): Lowest cash toclose; flexible if you might sell or refi in a few years.

  • Discount points: Pay upfront for a lower rate for the life of the loan. Use break-even:     points cost ÷ monthly savings = months to make it worthwhile.
  • Temporary buy-down (e.g., 2-1): Lower payment in years 1–2, then resets. Great if you can fund it     with a seller credit.

Ask us for a comparison side by side: 0 pts vs. 1-point vs.2-1—showing cash to close, monthly payment, and 5-year cost.

4) Down payment truths

You don’t need 20% down to be competitive. Plenty of solid options existwith 3–10% down. What wins offers: a fully underwritten approval, cleanterms, and a smart credit/buy-down plan—not just a big down payment.

5) Remote-work reality check

If you commute 2–3 days/week, a slightly longer drive might trade for abetter price and payment. Homes with true workspace (a door that shuts) stillresell and rent better. Factor Wi-Fi, parking, and transit into the monthly.

6) Four steps to be offer-ready in 2weeks

  1. Docs in one place: W-2/1099s, pay stubs, bank statements, tax returns if needed.
  2. Full underwriting (not just pre-qual) for real certainty.
  3. Choose the structure: ) 0pts vs. points vs. 2-1 with break-evens labeled.
  4. Neighborhood  reps: Tour 3 areas mid-week and at night; track days-on-market and price     cuts to target a seller credit for your buy-down.


Mini examples

  • First-timer, 7-year horizon: 2-1 buy-down funded by seller credit can smooth the early years and     keep your emergency fund intact.
  • Move-up, overlapping homes: Skip points, conserve cash, and negotiate a seller credit to offset     carrying costs.


Common pitfalls (skip these

  • Budgeting with P&I only (forgetting taxes/insurance/HOA).
  • Paying points without knowing if you’ll hit the break-even.
  • Big credit changes during escrow (new car/furniture = risky).
  • Assuming “20% or nothing.”
