This page is for people who want to understand more about negative equity. You may be paying off a mortgage, or a first-time buyer who wants to understand negative equity before getting a mortgage. Find out more about what to do if you're an existing customer in negative equity.
Negative equity is when your property becomes worth less than the remaining value of your mortgage. To be in negative equity, the value of your house must fall below the amount you still owe on your mortgage.
How to work out your equity
Equity is the value of your property that you own outright. To work out your equity, you’ll need to know:
Current value of your property minus outstanding mortgage amount equals your equity in the property.
People often find themselves in negative equity due to falling house prices. When prices fall, the number of households in negative equity tends to rise. It’s a bigger problem during recessions, when house prices can experience bigger drops.
Negative equity example
Bill bought a house worth £180,000. He did this with a £20,000 deposit and a mortgage of £160,000.
After two years of living in the property, he’d paid off £10,000 of his mortgage.
He got his house valued again – and found that it was now worth £100,000.
He still owes £150,000 on his mortgage and his house is now worth £100,000, so he has negative equity of £50,000.
Interest-only mortgages can increase the risk of negative equity. This is because you only ever pay the interest on the amount you borrow, rather than repaying the mortgage sum.
The total amount you owe is repaid at the end of the mortgage.
Because you’re not paying off your mortgage amount, you don’t build equity in your property, so a fall in property prices could put you at risk.
Moving home and negative equity
Negative equity can mean selling your home for less than the value of the mortgage you took out to buy it.
This is because you’ll have an outstanding amount of money on the mortgage that you have to pay back after the sale. If you don’t have savings or other funds available, it may be difficult to pay this and it may not be easy for you to sell your house.
You can find out whether you are in negative equity by following these steps:
If the value of your property is less than the amount you owe on your mortgage, you are in negative equity.
If you’re thinking of buying a house and want to protect yourself against negative equity, here are some steps that could help:
Try not to worry if you discover you’re in negative equity – if it’s just by a small amount, changing house prices may move you back into positive equity. You have a few options to try and get back into positive equity:
Continue making repayments as you normally would and wait for equity to build. This is a long-term option for people not thinking about moving house.
Paying more than your agreed monthly mortgage payments can reduce how much you owe more quickly. Find out more about overpayments.
