UK Mortgage Tips
- Lower LTV bands often unlock better rates, so increasing deposit can reduce monthly payment significantly.
- Overpaying early years can cut large interest cost over full term.
- Arrangement fees may be cheaper upfront than adding to loan (to avoid interest on the fee).
- Interest-only deals need a clear repayment strategy for the capital at term end.
Frequently Asked Questions
What is LTV?
+
LTV (Loan-to-Value) is loan amount divided by property value. Lower LTV usually means better mortgage rates.
Repayment vs interest-only?
+
Repayment reduces principal every month and clears balance by term end. Interest-only pays interest each month and principal remains due at the end.
Are stamp duty and solicitor fees included?
+
No. This calculator focuses on mortgage costs only (payments, interest, and optional arrangement fee handling).
