The Chen family is buying a $340,000 home in Columbus, Ohio. Combined income $115,000, 10% down payment, 30-year fixed at 7.125%.
Takeaway: Columbus/Franklin County averages are the reference baseline. Property tax rates and insurance premiums shift significantly by ZIP code and HOA status. Plug your actual numbers in above.
We default to state-average millage rates. County and municipal rates vary 40%+ within a single state. Ohio ranges from 0.8% (rural counties) to 2.4% (Cuyahoga/Cleveland area). Always cross-check your specific county assessor's published effective rate.
Property Tax by StateHomeowner association fees add $100-$800/month in condos and planned communities. Condos in urban markets often run $400-$700/month. If your property has HOA, add it manually to any payment estimate — it directly affects your debt-to-income ratio for loan qualification.
HOA Fee CalculatorClosing costs typically run 2-5% of the loan amount — around $6,000-$15,000 on a $300K home. Lender fees, title insurance, escrow, and prepaid taxes add up fast. These are due at closing in cash, not rolled into the mortgage by default.
Closing Costs CalculatorPrivate mortgage insurance (PMI) costs 0.5-1.5% of the loan annually until you reach 20% equity. On a $300K loan at 1%, that's $250/month. PMI cancels automatically at 78% LTV under federal law — but you can request removal at 80%.
National home price appreciation has averaged ~4% annually since 1968, but markets diverge dramatically. Sun Belt metros averaged 10%+ during 2020-2022; coastal markets often lag the national average during correction cycles. Local supply constraints are the main driver.
If you've lived in the home 2 of the last 5 years, you can exclude $250K (single) or $500K (married) of gain from federal capital gains tax. Many calculators show gross profit without applying this exclusion. Relevant when projecting sale proceeds.

On a $400,000 loan: 1 point costs $4,000 upfront. If it reduces your rate from 7.25% to 7.00%, monthly payment drops from $2,730 to $2,661 — saving $69/month. Break-even: $4,000 ÷ $69 = 58 months (4.8 years). If you stay longer, points were worth it. If you sell or refinance before 58 months, you wasted money.
One mortgage point equals 1% of your loan amount paid upfront at closing. Each point typically reduces your interest rate by 0.25% (though this varies by lender and market conditions). It's essentially prepaying interest for a lower rate.
Break-even = Cost of points ÷ Monthly savings. Example: $4,000 in points saves $80/month = 50-month break-even. If you stay beyond 50 months, buying points was a smart financial move.
Yes! Points paid on a home purchase are generally fully deductible in the year paid (if you itemize). For refinances, the deduction is amortized over the loan life. Consult a tax advisor for your situation.
Buying points makes sense if: (1) you plan to stay in the home past the break-even point, (2) you have cash available that wouldn't earn more elsewhere, and (3) you won't refinance before break-even. Avoid points if you may move or refi within a few years.
Discount points are prepaid interest that lowers your rate. Origination points (or origination fees) are lender compensation for processing your loan. Both cost 1% of loan per point but serve different purposes. This calculator covers discount points only.
Most lenders allow 1-3 discount points per loan. Each point typically reduces the rate by 0.25%. Some lenders offer fractional points like 0.5 or 1.5. The maximum is usually capped at 3-4 points as the rate reduction diminishes with each additional point purchased.
A larger down payment reduces your loan balance and may eliminate PMI, while points reduce your interest rate. If you already have 20% down, points may be worthwhile for long-term savings. If below 20%, putting extra cash toward the down payment to avoid PMI usually saves more.
Points can make sense when refinancing if you plan to stay in the home long enough to reach break-even. Calculate the break-even period by dividing the point cost by monthly savings. If you might refinance again within 3-5 years, skip the points.
Calculate the total cost of each option over your expected time in the home. A no-point loan has higher monthly payments but lower upfront costs. A loan with points costs more upfront but saves monthly. The break-even point determines which is cheaper for your timeline.
Yes. Seller-paid points are allowed as part of seller concessions. The seller can contribute toward your closing costs including discount points, typically up to 3-6% of the purchase price depending on your loan type and down payment amount.
Point Cost = Loan Amount × Points × 1%
Break-Even = Cost of Points ÷ Monthly Payment Savings
Lifetime Savings = Monthly Savings × Loan Term − Cost of Points
