Mortgages Guide

A mortgage is almost certainly the largest sum you will ever borrow, and the decisions you make at each application or remortgage have a direct, lasting effect on your finances. Most lenders cap borrowing at around 4.5x gross income, stress-test affordability at rates 2–3% above today's, and price every product by loan-to-value band. The gap between a 95% LTV deal at 5.90% and a 60% LTV deal at 4.20% is 1.70% — roughly £4,420 of additional interest on a £260,000 mortgage over just two years. Rolling onto a Standard Variable Rate of 6.5–8% at the end of a deal is the single most expensive mistake a borrower can make, yet it happens by default to anyone who does not act.

This guide walks through how mortgages actually work: repayment versus interest-only structures, fixed versus tracker rates, how lenders assess affordability, the full 10-to-16-week buying process, and the upfront costs beyond your deposit. It covers buy-to-let lending and the impact of Section 24, remortgage timing, early repayment charges, and the seven mistakes that catch most borrowers out. It follows Laura and Ben, a Bristol couple buying their first home for £325,000 with a £65,000 deposit, and shows how their broker secured a 5-year fix at 4.55% and saved them roughly £1,620 over the deal period through fee analysis alone.
