Can I Afford My House on One Income After a Divorce?

It may be possible, depending on the legal, financial, and property details involved. Determining whether a house remains affordable on one income requires running the actual numbers rather than assuming the current mortgage payment will simply continue to work.
Recalculating the debt-to-income ratio
A mortgage that comfortably fit within a combined household income can easily exceed 50% of a single income, well above what most financial guidance considers sustainable, once only one spouse's earnings are supporting the payment.
Factoring in additional post-divorce costs
Beyond the mortgage itself, a single income now typically needs to cover costs previously split, property taxes, insurance, maintenance, and possibly childcare if custody arrangements require it, all factors worth including in a realistic affordability assessment.
Options if the numbers don't work
If the mortgage genuinely isn't affordable on one income, options include refinancing into a longer loan term to lower monthly payments, selling and downsizing to a more affordable property, or negotiating spousal or child support that specifically accounts for the housing cost as part of the settlement.
Renting out a portion of the home as a bridge option
Some spouses keeping a larger home temporarily rent out a room or an accessory dwelling unit to help cover the mortgage during a transition period, a middle-ground option between an immediate sale and covering the full payment on one income, though it requires comfort with having a tenant present.
