Struggling With Your Mortgage?

Higher interest rates and the rising cost of living mean more people are finding it difficult to keep up with their mortgage payments. Others feel trapped on an uncompetitive deal, unable to switch even though they want to and have tried — sometimes referred to as being a “mortgage prisoner.”

What’s Happening to Mortgage Rates?

Mortgage interest rates are still significantly higher than they were a few years ago, when some deals were available at just 1–2%.

While there have been periods of rate reductions, these have been offset at times by further increases. This includes all broker-available products as well as direct-only offers.

The Complete Mortgage FAQ Guide

Comprehensive answers to all your property and finance questions, brought to you by AgentSuite.uk.

1. First-Time Buyers & Deposits

How much deposit do I actually need to buy a home? +
Typically, you need a minimum of 5% to 10% of the property's value. However, at AgentSuite.uk, we advise aiming for 15% to 20% if possible. A larger deposit lowers your Loan-to-Value (LTV) ratio, which unlocks much cheaper interest rates and lowers your monthly payments.
What are the hidden costs of buying a house? +
Beyond your deposit, you must budget for Stamp Duty (if applicable), valuation fees, conveyancing (legal) fees, mortgage arrangement fees, and moving costs. We recommend setting aside an extra £2,000 to £4,000 for these administrative expenses.

2. Remortgaging & Interest Rates

Fixed-Rate vs. Variable-Rate: Which is better? +
A Fixed-Rate mortgage guarantees your monthly payments won't change for a set period (e.g., 2 or 5 years), offering peace of mind. A Variable or Tracker rate goes up and down with the Bank of England's base rate, meaning your payments could increase, but you might also benefit if rates drop.
What is an SVR and why should I avoid it? +
The Standard Variable Rate (SVR) is your lender's default interest rate, which you fall onto once your fixed deal ends. It is almost always significantly more expensive. At AgentSuite.uk, we strongly advise starting your remortgage process 6 months early to avoid paying the SVR penalty.
Can I remortgage with my current lender? +
Yes, this is known as a 'Product Transfer'. It is often faster and involves fewer credit checks than switching to a new bank. However, you should always compare their offer against the wider market to ensure you are getting the best deal.

3. Credit Scores & Affordability

How much can I borrow for a mortgage? +
Typically, lenders will offer between 4 and 4.5 times your annual income (or combined income for joint applications). However, they will also heavily scrutinize your monthly outgoings, debts, and lifestyle costs through an 'affordability check' before making a final offer.
Will a missed payment or default stop me from getting a mortgage? +
Not necessarily, but it makes it harder. Recent missed payments are red flags to high-street lenders. If your defaults are older (e.g., 3-4 years ago), their impact lessens. Specialist 'adverse credit' lenders exist, but they usually charge higher interest rates.

4. Buy-to-Let & Moving Home

How do Buy-to-Let (BTL) mortgages differ from standard ones? +
BTL mortgages are largely business transactions. They usually require a larger deposit (typically 25%), are often 'interest-only', and approval is based heavily on the property's expected rental income rather than just your personal salary.
Can I take my current mortgage to a new property? +
Yes, this process is called 'porting'. However, it is not guaranteed. You still have to re-apply and pass the lender's current affordability checks for the new property. If you are moving to a more expensive home, you may need to borrow additional funds on a different interest rate.
