See the true cost before you make an offer
Spring is peak home buying season — 40% of US home purchases happen between March and June. It's also when small calculation mistakes cost the most: a missed PMI cost, an underestimated property tax bill, a closing cost surprise. ConvertMart's Spring Home Buying Hub bundles 35+ calculators that model the full monthly cost of homeownership — principal, interest, taxes, insurance, HOA, PMI, maintenance reserve — so the number you see is what you'll actually pay. Use the affordability calculator first to set a realistic price range, then run individual properties through the full mortgage calculator with local tax rates. Don't skip the closing cost calculator: closing costs run 2-5% of purchase price and are the biggest 'surprise' expense for first-time buyers.
Start here. Calculate how much house you can afford based on income, existing debt, and down payment. Run specific properties through the full mortgage calculator to see monthly PITI (principal, interest, taxes, insurance). Compare 15-year vs 30-year terms and see lifetime interest savings.
Down payment under 20% triggers private mortgage insurance (PMI) at 0.5-1.5% annually. Closing costs run 2-5% of purchase price — loan origination, title insurance, appraisal, escrow, transfer taxes. These calculators show the real all-in cash needed to close.
Property tax varies 10x between US states (New Jersey averages 2.47%, Hawaii averages 0.28%). Homeowners insurance averages $1,400/year nationally but varies by weather risk, home age, and roof type. Both are included in monthly PITI — budget accordingly.
The rent-vs-buy decision depends on how long you plan to stay, the opportunity cost of the down payment, market appreciation, and tax benefits. These calculators run both scenarios over 5, 10, and 30 year horizons including the opportunity cost of not investing the down payment.
Once you've built equity, HELOCs let you borrow against it at rates typically 4-6 points below unsecured credit. Calculate maximum HELOC availability (up to 85% combined LTV), compare rates against personal loans and credit cards, and model debt consolidation scenarios.
FHA loans (3.5% down), VA loans (0% down for veterans), USDA loans (0% down in rural areas), and state first-time buyer grants can dramatically reduce upfront cash requirements. These calculators factor in program-specific PMI/MIP rules.
