Budget beyond the deposit
A home purchase can involve legal fees, surveys, moving costs, potential property taxes and ongoing repairs. Property taxes differ across UK nations and depend on the transaction.
Before deciding what to borrow, calculate the total housing cost including insurance, utilities, service charges where relevant and a maintenance allowance.
Questions to ask
- What upfront costs have you included?
- Is your emergency buffer preserved after moving?
Understand repayment and interest-only
A repayment mortgage normally reduces capital and interest through scheduled payments. An interest-only mortgage generally requires a separate plan to repay the capital at the end.
A fixed rate may change at the end of the fixed period. Variable interest and future mortgage offers cannot be predicted by a basic calculator.
Questions to ask
- How would repayments change at a higher assumed rate?
- What happens when a promotional or fixed rate ends?
Check affordability and protection
Lenders assess affordability using their own criteria. A monthly repayment calculation is not a lending decision or an offer.
Missed mortgage payments may put your home at risk. Seek regulated mortgage advice where appropriate.
Questions to ask
- Could your household manage a period of lower income?
- Does the proposed repayment term fit your plans?
