Practical guidance
What belongs in the number
- Loan payment: principal and interest.

- Operating costs: electricity, water, internet, refuse, landscaping, and pest control.
- Reserves: money set aside for roof, paint, pumps, appliances, catchment, septic, or storm repairs.
Decision check
Use the result before making an offer
Compare this total with rent, expected take-home pay, savings after closing, and the cost of deferred repairs. A payment that fits the lender ratio can still squeeze the household when insurance, electricity, and maintenance arrive.
