What is negative equity and what can I do about it?
Negative equity means your outstanding mortgage balance is higher than your property's current market value, so selling would not raise enough to repay the mortgage in full. It typically arises when house prices fall after purchase, especially for buyers with small deposits. Options include staying put and continuing to pay down the mortgage, or in some cases negotiating with the lender.
Full answer
Negative equity is more common after periods of falling or stagnant house prices, particularly for buyers who purchased with a small deposit close to the top of a local market, and it constrains your options far more than simply owning a home outright. **How negative equity arises** If you bought a property for £200,000 with a 5% deposit (£10,000) and a £190,000 mortgage, and the property's market value later falls to £180,000 (while you have only paid down a small amount of the mortgage capital), you owe more (say £185,000 remaining) than the property is now worth (£180,000) -- a £5,000 negative equity position. Small-deposit buyers are especially exposed, since even a modest price fall can wipe out their thin equity cushion entirely. **Why it matters even if you are not planning to sell** If you can comfortably continue making your mortgage repayments and have no need to move, negative equity does not force any immediate action -- it is a paper problem, not a cash-flow one, as long as you keep paying. However, it becomes a serious practical issue if you need or want to sell, since the sale proceeds would not cover repaying the mortgage in full, meaning you would need to find the shortfall from savings or other means to complete a sale (unless the lender agrees to a specific arrangement). **Impact on remortgaging** Negative equity, or even just a very high loan-to-value ratio close to the property's current value, can make it difficult or impossible to remortgage to a new deal when your current fixed rate ends, since most lenders require a minimum amount of equity (commonly at least 5-10%) to offer their best rates or, in some cases, to lend at all. This can leave homeowners stuck on their existing lender's standard variable rate, often notably higher than competitive fixed deals, until enough equity is rebuilt. **What you can do** Options include: continuing to pay down the mortgage capital as normal (each repayment gradually reduces negative equity even if prices stay flat), overpaying the mortgage if you have spare cash and no penalty applies, waiting for house prices in your area to recover, or speaking to your existing lender about a "product transfer" onto a new rate with the SAME lender (which usually does not require the same loan-to-value checks as switching to a new lender, since you are not increasing their risk). Selling while in negative equity generally requires either finding the shortfall in cash or, in rare cases, negotiating a shortfall arrangement with the lender, which can affect your credit record. **Worked example** A homeowner with a £185,000 mortgage on a property now worth £180,000 continues making normal monthly repayments. After two years, their mortgage balance has fallen to £178,000 through capital repayments, and if the local property market has also recovered modestly to £190,000, they are back into positive equity (£12,000) without having done anything beyond continuing to pay their mortgage as normal. **Practical tip** If your fixed-rate deal is ending and you suspect you may be in or close to negative equity, contact your existing lender well in advance to discuss a product transfer rather than assuming you must switch lenders (which is where equity requirements bite hardest) -- staying with your current lender is usually the most realistic route to a better rate while equity remains thin.
