DTI compares your monthly debt payments to your gross monthly income. Lenders typically want your total DTI (including housing) below 43%, though some allow up to 50% with strong compensating factors. ### How much down payment do I need? Conventional loans require 3-20% down, FHA loans require 3.5%, and VA/USDA loans may require 0%. A 20% down payment avoids PMI (Private Mortgage Insurance) and typically gets better rates. ### What costs are not included in monthly payments? This calculator may not include PMI, utilities, maintenance, or repairs. Budget an additional 1-2% of home value annually for maintenance and unexpected repairs. ### Should I buy the maximum I can afford? Not necessarily. Consider your lifestyle, job stability, and other financial goals. Many advisors recommend spending no more than 25-28% of gross income on housing to maintain financial flexibility. ### How do property taxes affect affordability? Property taxes vary significantly by location (0.3% to over 2% of home value). Higher taxes reduce your maximum home price since they're included in your monthly payment calculations. ### What is the 28/36 rule for buying a home? The 28/36 rule is a guideline lenders use: spend no more than 28% of gross monthly income on housing costs and no more than 36% on total debt payments. This helps ensure you can comfortably handle mortgage obligations alongside other financial responsibilities. ### How does my credit score affect home affordability? A higher credit score (740+) qualifies you for lower interest rates, which increases the home price you can afford. For example, a 1% rate difference on a $300,000 loan changes your monthly payment by roughly $180. Improving your score before applying can save tens of thousands over the life of a loan. ### Can I include a spouse's income in the affordability calculation? Yes. If applying jointly, combine both gross incomes and both monthly debt payments. Joint applications often qualify for a larger loan, but both applicants' credit scores and debts are considered by the lender. ### What is PMI and when is it required? Private Mortgage Insurance (PMI) is required on conventional loans when your down payment is less than 20%. PMI typically costs 0.5-1% of the loan amount annually and is added to your monthly payment. Once you reach 20% equity, you can request PMI removal. ### How much should I save before buying a home? Plan for three main costs: the down payment (3-20% of home price), closing costs (2-5% of purchase price), and an emergency fund covering 3-6 months of housing expenses. Having adequate savings prevents financial stress after the purchase. ## Related Tools - [Mortgage Calculator](https://findutils.com/finance/mortgage-calculator/) - [Down Payment Calculator](https://findutils.com/finance/down-payment-calculator/) - [Refinance Calculator](https://findutils.com/finance/refinance-calculator/) - [Loan Calculator](https://findutils.com/finance/loan-calculator/) - [Amortization Calculator](https://findutils.com/finance/amortization-calculator/) - [Debt Payoff Calculator](https://findutils.com/finance/debt-payoff-calculator/) - [Savings Calculator](https://findutils.com/finance/savings-calculator/) - [Credit Card Payoff Calculator](https://findutils.com/finance/credit-card-payoff-calculator/)
