To determine how much one may qualify for a home loan, several key factors affect the calculation:

• Income and Debts: Lenders look at gross monthly income and total monthly debts. A common guideline is that housing costs should not exceed 28%-31% of gross income, and total debts (housing plus other debts) should not exceed 36%-43% of income. This is often referred to as the 28/36 or 31/43 rule depending on loan type.
• Down Payment: The size of the down payment affects the loan-to-value ratio and loan qualification. FHA loans might require as little as 3.5% down; conventional loans generally require a minimum of 3%.
• Credit Score and History: Minimum credit scores usually start at around 620 for conventional loans and 580 for FHA loans, with higher scores improving loan terms.
• Loan Type: Different loan programs (Conventional, FHA, VA, USDA) have different qualifying criteria including debt-to-income ratios.
• Employment and Age: Lenders prefer steady employment and consider the borrower’s age related to the loan term.
• The exact loan amount one qualifies for depends on all these factors plus current interest rates and local property taxes and insurance costs.

Lenders typically want your monthly housing payment to be about 28-31% of your gross monthly income, and your total monthly debts including the mortgage to be under 36-43%. For example, if you make $5,000 pre-tax per month, you might qualify for a home with monthly payments around $1,400 to $1,550, considering other debts.

If specific numbers like income, current debts, credit score, and down payment are provided, a more precise estimate can be made. Otherwise, using online calculators with these inputs can give a close estimate for qualification amount.
