About House Affordability

House affordability is determined by several factors including your income, existing debt, down payment, interest rates, and local property taxes. This calculator uses standard financial ratios used by mortgage lenders to help estimate a reasonable home price range for your financial situation.

Key Affordability Ratios
  • Debt-to-Income Ratio (DTI): The percentage of your monthly gross income that goes toward paying debts. Most lenders prefer a DTI of 36% or less, though some loan programmes allow up to 43% or higher.
  • Housing Ratio (Front-End Ratio): The percentage of your gross monthly income that goes toward housing costs (PITI: Principal, Interest, Taxes, Insurance). Typically, lenders prefer this ratio to be 28% or less.
Other Considerations
  • Down Payment: A larger down payment increases purchasing power and can help you avoid private mortgage insurance (PMI).
  • Credit Score: Better credit scores qualify you for lower interest rates, which increases affordability.
  • Emergency Fund: Homeownership comes with unexpected expenses. It's wise to maintain an emergency fund separate from your down payment.
  • Future Plans: Consider future financial changes like career advancements, growing family, or other major expenses when determining affordability.

Why Affordability Matters

Affordability is a key factor when purchasing a home. Knowing what you can afford helps avoid financial strain later on. Here are some reasons why understanding affordability is crucial:

  • It helps you set a realistic budget for your home search.
  • It allows for better financial planning and management.
  • Avoids overextending yourself with mortgage payments.
  • Ensures you can comfortably handle other expenses.

Key Ratios That Influence Calculations

The calculator uses important financial ratios to determine your affordability. Two of the most critical ratios are the Debt-to-Income (DTI) ratio and the Housing Ratio. Understanding these can guide your home-buying decisions:

  • Debt-to-Income Ratio (DTI): This is the percentage of your gross monthly income that goes towards paying debts. Most lenders prefer a DTI of 36% or lower.
  • Housing Ratio: This measures the percentage of your income spent on housing costs, ideally kept below 28% for most lenders.

Understanding Monthly Payments

One of the key outputs of the calculator is the estimated monthly payment. This includes principal, interest, property taxes, and insurance, often referred to as PITI. Knowing your monthly payment helps you plan your budget and ensures you won’t face surprises later. The calculator breaks down these costs, making it easier to grasp where your money will go each month.
