    Frequently Asked Questions

    How much house can I afford?

    Most lenders use the 28/36 rule: Your housing payment should not exceed 28% of your gross monthly income, and total debt payments should not exceed 36%.

    What is the 28/36 rule?

    The 28% front-end ratio means housing costs (PITI) should be under 28% of gross income. The 36% back-end ratio includes all debt payments.

    How does my credit score affect affordability?

    Higher credit scores qualify for lower interest rates, which increases how much house you can afford. A 760+ score gets the best rates.

    What is PMI and how does it affect costs?

    Private Mortgage Insurance is required when down payment is less than 20%. It typically costs 0.5-1% of the loan amount annually.

    How much should I save for a down payment?

    While 20% avoids PMI, many conventional loans accept as little as 3% down. FHA loans allow 3.5% down.

    What are closing costs?

    Closing costs are 2-5% of the home price and include appraisal, title insurance, origination fees, and prepaid taxes/insurance.

    How does my debt-to-income ratio affect approval?

    Lenders prefer DTI below 43%. A lower DTI means you can qualify for a larger loan and better rates.

    Should I consider property taxes and insurance?

    Yes, these are part of PITI (Principal, Interest, Taxes, Insurance) and are often escrowed into your monthly payment.
