Should you overpay your mortgage?

How overpayments cut interest, when to save instead, and offset mortgages compared. This guide walks through the essentials in plain English so you know what to expect before speaking to a broker or lender.\n\nStart with the basics. Every mortgage lender applies its own criteria on income, deposit, credit history and property type. What one lender rejects, another will happily approve, which is why speaking to a whole-of-market broker often makes a real difference.\n\nUnderstanding the numbers matters. Lenders look at affordability using stress-tested interest rates, not just today's headline rate. They also consider your outgoings, dependants and existing credit commitments. A broker can run the numbers with several lenders before you commit to a full application.\n\nTiming is another factor people underestimate. From Agreement in Principle to completion typically takes eight to sixteen weeks in the UK, longer for new builds or complex chains. Getting your paperwork together early, including ID, three months of bank statements and proof of income, keeps the process moving.\n\nIf you take one thing away, it is that advice is worth it. A good adviser will explain the trade-offs, be transparent about their fees, and only recommend a product that genuinely fits your circumstances. If a broker feels pushy or vague on fees, walk away and speak to another.\n\nReady to compare brokers who cover your area?
