🏠 How Much House?
The magic number that lenders use to determine reasonable mortgage amounts is called the Debt-to-Income ratio (DTI). DTI is your monthly debt payments compared to your gross monthly income. In a broader financial context, DTI is sometimes called the Household Debt Service Ratio (DSR).
This view uses your space’s calculated DTI to estimate an amount mortgage lenders are likely to approve.

[-] Savings, as calculated by holdings in this space to use toward the down payment.
Down Payment Amount
Cashflows 💸
[-] Income and monthly debt expenditure determine your DTI ratio, one of the biggest factors in mortgage lending. Monthly debt payments here include other loans, from current mortgage, to car loans, and student loans. For credit cards, it's just the carried interest portion of your bill.
Mortgage Terms 🏦
[-] There are a million types of mortgage, but here we default to the best rate at an open credit union (not-for-profit) lender. To see 150+ rates compared, see our blog post on Credit Union Mortgage Rates.
Debt Reality Check ⚖️
[-] Most lenders dealing with qualified mortgages want to see DTI below 43%, though some loans may stretch to 50% in special cases. While these maximums represent what lenders will approve, financial experts typically recommend keeping DTI below 36% to maintain financial flexibility and account for life's surprises.
Current DTI ratio
The Boring Details 🥱
[-] Over the last few decades, average DTI has typically varied between 10-13% (see below), with extremes during subprime mortgages and COVID. Households with no debt, whether renters or owners, bring this figure down significantly. (St. Louis Fed)
On average, Americans (renters or homeowners) spend around 33% on housing, with renters having a higher median housing cost as a percentage of income (31.0%) compared to homeowners (21.1% for homeowners with a mortgage and 11.5% for those without a mortgage) (census.gov).
