Negative Equity Guide — What It Means and What You Can Do

What negative equity is, how it happens, your options if you're in negative equity, and how it affects remortgaging, moving house, and selling your home.

Negative equity happens when your home is worth less than what you owe on your mortgage. Here’s what it means, how it affects you, and what your options are.

What Is Negative Equity?

Term Meaning
Equity The portion of your home you own outright (property value minus mortgage balance)
Positive equity Your home is worth more than your mortgage — you have equity
Negative equity Your home is worth less than your mortgage — you owe more than it’s worth
Loan-to-Value (LTV) Your mortgage as a percentage of the property value — over 100% means negative equity

Example

Detail Amount
Property value when you bought it £250,000
Mortgage £237,500 (95% LTV)
Current property value £220,000 (prices fell 12%)
Current mortgage balance £230,000 (paid off some)
Equity £220,000 – £230,000 = –£10,000
Current LTV 230,000 ÷ 220,000 = 105%

What Causes Negative Equity?

Cause How it happens
House price falls Regional or national price drops reduce your property’s value
High LTV mortgage Buying with a 5%–10% deposit gives very little buffer
Interest-only mortgage Balance doesn’t reduce — any price drop causes negative equity
Additional borrowing Taking out more lending against the property
Overpaying for the property Paying above market value (e.g. in a bidding war)
Local factors New development, infrastructure changes, or area decline

Does Negative Equity Matter?

Situation Impact
You’re staying put No immediate impact — keep paying your mortgage as normal
You want to remortgage Difficult with a new lender; product transfer usually possible
You need to sell You’d need to pay the shortfall — or negotiate with your lender
You want to move Complicated — may need a negative equity mortgage
You’re separating/divorcing Can complicate property division
You lose your job / can’t pay More serious — lender may repossess, leaving you with residual debt

Your Options

Option 1: Stay and Wait

Detail Information
Strategy Continue making mortgage payments and wait for prices to recover
Timeframe Price recovery could take 2–10+ years depending on the market
Risk Low — as long as you can afford payments
Cost Nothing extra — you’re just continuing normal payments
Best for Most people — especially if you like your home and can afford it

Option 2: Overpay Your Mortgage

Detail Information
Strategy Pay more than your minimum payment to reduce the balance faster
Typical overpayment limit 10% of the outstanding balance per year (check your mortgage terms)
Benefit Reduces your negative equity and total interest paid
Example Overpaying £200/month on a £230,000 mortgage saves years and thousands in interest
Best for People with spare income who want to fix negative equity faster

Option 3: Product Transfer with Your Current Lender

Detail Information
Strategy Move to a new mortgage deal with your existing lender
Advantage No new valuation needed — lender already has the mortgage
Availability Most lenders offer product transfers even in negative equity
Rate May not be the best rate available, but usually better than standard variable rate
Best for When your fixed rate ends and you want to avoid SVR

Option 4: Negative Equity Mortgage (Porting)

Detail Information
Strategy Transfer your mortgage to a new property when you move
How it works Existing lender allows you to port the mortgage, including the negative equity element
Availability Not all lenders offer this; depends on your circumstances
Restriction The new property usually needs additional borrowing — assessed on affordability
Best for People who need to move (job relocation, family change)

Option 5: Shortfall Sale

Detail Information
Strategy Sell the property for less than you owe, with your lender’s agreement
Shortfall You may still owe the difference as an unsecured debt
Credit impact Serious — similar to a default or arrangement
When considered Usually a last resort, or when circumstances make staying impossible
Lender agreement Required — you cannot just sell without clearing the mortgage

Remortgaging in Negative Equity

Option Possibility
New lender Very unlikely — no lender will offer 100%+ LTV on a new application
Current lender product transfer Usually available — your best option
Switch to repayment from interest-only Helps reduce balance — good long-term strategy
Government schemes Currently no specific negative equity scheme; check Help to Build or local authority schemes

If You Can’t Afford Your Payments

Step Action
1 Contact your lender immediately — they must treat you fairly
2 Ask about a payment holiday (temporary)
3 Ask about switching to interest-only temporarily
4 Ask about extending your mortgage term to reduce monthly payments
5 Get free debt advice (StepChange, National Debtline, Citizens Advice)
6 Check if you’re eligible for Support for Mortgage Interest (SMI)
7 As a last resort, discuss a voluntary sale with your lender

Support for Mortgage Interest (SMI)

Detail Information
What it is A government loan that pays mortgage interest if you’re on certain benefits
Who qualifies UC, Income-based JSA, Income-related ESA, Pension Credit, Income Support recipients
Waiting period 39 weeks (9 months) for most claimants; none for Pension Credit
Payment Government pays interest directly to your lender
Repayment It’s a loan — secured against your property, repaid when you sell or transfer ownership

How Quickly Can Negative Equity Resolve?

Factors Detail
House price growth Average UK house prices have grown ~3–5% per year historically
Mortgage payments Each repayment mortgage payment reduces your balance
Overpayments Accelerate balance reduction

Example Recovery Timeline

Starting position Year 1 Year 3 Year 5
Property value: £220,000 £226,600 (3% growth) £240,500 £255,100
Mortgage balance: £230,000 £225,800 (regular payments) £216,800 £207,000
Equity –£800 +£23,700 +£48,100

In this example, negative equity resolves within about 1 year with normal growth and regular payments.
