A $750,000 mortgage typically costs between $4,700 and $4,900 per month for principal and interest on a 30-year fixed loan at current rates (approx. 6.5% - 6.7%). Total payments, including taxes and insurance, often exceed $4,800 to $6,000+ per month depending on location.
Based on this calculation, to afford a $750,000 house with a 20% down payment and a 30-year mortgage at 7% interest, you would need to earn at least $172,800 per year. However, this is just a rough estimate, and your individual circumstances may vary.
What Is the Total Cost of a $700K Mortgage? A $700,000 30-year mortgage with a 6.00% interest rate (which, as noted above, costs around $4,200 monthly) has a total cost of $1,510,867.
However, most lenders still require your score to be at least 600 for an insured mortgage, even with a co-signer. How long does it take to raise my score enough to buy a home? Raising your credit score enough to buy a home (typically up to at least 600–680) can take anywhere from about 3 to 12 months.
Ways to pay off your home loan faster
The short answer. Most buyers need to earn $175,000 to $235,000 per year to afford a $700,000 home. This assumes average interest rates, a standard loan term, and a modest down payment. Your actual income needs may vary based on your debt, credit score, and monthly expenses.
For a house priced at $750,000, this means you would need a minimum deposit of $150,000. This is calculated by multiplying $750,000 by 0.20 (20%). Therefore, to buy a house priced at $750,000 without incurring LMI, you would need to save at least $150,000 for the deposit.
Mortgage amount
Taxpayers can deduct the interest paid on qualified residences for up to $750,000 in total mortgage debt (the limit is $375,000 if married and filing separately). Any interest paid on first, second or home equity mortgages over this amount is not tax-deductible.
What Are the Limits on Mortgage Tax Interest Deductions? The Tax Cuts and Jobs Act reduced the limit on deductible mortgage debt to $750,000 for new loans taken out after 12/15/2017.
At the time of writing (December 2025), the average monthly repayments on a £750,000 mortgage are £4,384. This is based on current interest rates being around 5%, a typical mortgage term of 25 years, and opting for a capital repayment mortgage. Based on this, you would repay £1,315,328 over the mortgage term.
The 3-7-3 Rule in mortgages isn't a loan type but a federal timeline from the TILA-RESPA Integrated Disclosure (TRID) rule, ensuring borrower protection by mandating disclosures within 3 business days of application, a 7-business-day wait between the initial Loan Estimate and closing, and another 3-day wait if significant changes (like APR) occur, giving borrowers time to review costs before committing to a loan.
Paying off a loan may help you reduce your DTI and qualify for a mortgage, but it could also drop your credit score a few points, so it may be better to reduce your overall debt balance but not pay off any loans or credit cards in full.

The 28/36 rule is a tool lenders could use to assess an applicant's potential risk for a new loan, specifically a mortgage. The rule suggests that a borrower use no more than 28% of their income on housing, and no more than 36% of their income on overall debts.
To afford a $700,000 house, you generally need an annual income between $180,000 to $235,000, depending on interest rates, down payment, and existing debts, with lenders often using the 28/36 rule (housing costs under 28% of gross income, total debt under 36%) to assess affordability. A 20% down payment ($140,000) is common, reducing your loan, but taxes, insurance, and other expenses add to the total monthly cost.
It's partly true: most negative items like late payments and collections are removed from your credit report after about seven years, but the underlying debt often still exists, and bankruptcies (Chapter 7) last 10 years, so your credit isn't entirely "clear" but mostly refreshed from old negatives. The 7-year clock starts from the date of the original delinquency, not when you paid it off or sent to collections, and the debt itself can still be pursued by collectors.
Lenders consider monthly housing expenses as a percentage of income and total monthly debt as a percentage of income. Both ratios are important factors in determining whether the lender will make the loan.
