Where this figure comes from
Your income, debts, and housing costs run through the GDS/TDS ratios at the current qualifying rate.
Why this is not your budget
It is a mathematical ceiling, not a target. Compare it with what your budget absorbs once taxes, heating, and your other expenses are paid.
What no lender has confirmed yet
It confirms neither the income a lender will use, nor your credit, the property, or mortgage insurance. No lender has said yes yet.
