Buying a second home can be a great investment or vacation opportunity, but it's a major financial commitment. Lenders are often stricter with second mortgages, and the costs go beyond just the monthly payment. This calculator helps you understand if you can comfortably afford a second home by analyzing your new Debt-to-Income (DTI) ratio. According to Investopedia, while you might get a loan with a DTI up to 43%, a lower ratio is much safer for your financial health (Investopedia).
This is your current financial situation based on data from your space. These figures are the baseline for calculating the affordability of a second home.
Annual post-tax income
Available savings for down payment
Existing annual debt payments (including current mortgage)
Enter the details of the second home you're considering. The monthly mortgage payment will be calculated based on these inputs.
Down payment amount
New mortgage principal
New monthly mortgage payment
Homeownership includes costs beyond the mortgage. A common guideline is the 1% rule, which suggests budgeting 1% of the home's value for annual maintenance (Forbes). Don't forget property taxes, insurance, and utilities.
Total additional monthly costs
This is the crucial calculation. We'll add your new housing costs to your existing debts to find your new DTI. Lenders look for a DTI of 43% or lower, but for a second home, a ratio under 36% is strongly recommended to maintain financial stability (Bankrate).
