Mortgage Types Explained:

Repayment Mortgage

You pay both capital and interest each month. At the end of the term, you'll own your property outright. This is the most common and recommended type of mortgage.

Interest-Only Mortgage

You only pay the interest each month. The original loan amount remains unchanged, so you'll need a repayment plan to pay off the capital at the end of the term.

Factors Affecting Your Mortgage Payments:

  • Property Price: Higher property values require larger loans and higher monthly payments
  • Deposit Size: Larger deposits reduce the loan amount and often secure better interest rates
  • Interest Rate: Even small rate differences can significantly impact monthly costs
  • Mortgage Term: Longer terms reduce monthly payments but increase total interest paid
  • Credit Score: Better credit ratings typically qualify for lower interest rates

Improve Your LTV

A larger deposit reduces your loan-to-value ratio, unlocking better interest rates. Even 5% more deposit can save thousands in interest over the mortgage term.

Consider Overpayments

Most lenders allow 10% overpayments annually. An extra £100/month on a £300k mortgage could save £50k+ in interest and reduce the term significantly.

Rate Strategy

With rates volatile, consider 2-year fixes for flexibility or 5-year fixes for security. Factor in arrangement fees when comparing mortgage deals.

Frequently Asked Questions

How accurate is this mortgage calculator?

Our calculator provides accurate estimates based on the information you enter. However, final mortgage terms depend on lender criteria, credit checks, and property valuations. Always get official quotes from regulated mortgage lenders.

What's the difference between monthly payment calculators?

Repayment calculators show payments that reduce both interest and capital. Interest-only calculators show lower monthly payments but require a separate plan to repay the loan amount at the end of the term.

How much deposit do I need for a mortgage?

Most UK lenders require a minimum 5-10% deposit for residential mortgages. However, larger deposits (15-25%+) typically secure better interest rates and lower monthly payments.

Can I get a mortgage with bad credit?

Specialist lenders offer mortgages for borrowers with poor credit, though rates are typically higher. Consider improving your credit score before applying or seek advice from a mortgage broker.
