The average monthly mortgage payment on a $750,000 home typically ranges between $3,500 and $4,900 for principal and interest, depending on interest rates (roughly 5.5% to 7%) and down payment size. With taxes, insurance, and potential HOA fees added, the total monthly cost is often over $4,800.
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.
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.
To afford an $800,000 mortgage, you generally need an annual income between $180,000 and $260,000, but this varies significantly with interest rates, your down payment, and existing debts; a good guideline is using the 28/36 rule (housing costs < 28% of gross income, total debts < 36%) to find your specific need. Higher interest rates and more debt mean you'll need a higher income to qualify.

Short-term savings: Renting is cheaper than buying in the short term because you don't need a big down payment or lump sum to buy a house. Moving flexibility: You have much more flexibility with changing your home and moving around. This is great for individuals not set on living in the same place for years to come.
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.
If we assume about about a third of your income is dedicated to housing costs, multiply that $57,600 figure by three to approximate the minimum income you'd need to earn to afford a $750K house: $172,800.

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?
