House Buyout Summary
How to Calculate a House Buyout in the UK
When a relationship ends or co-owners decide to part ways, one person often stays in the home while "buying out" the other. This process is legally known as a transfer of equity. To determine the fair payment, you must first establish the accurate market value and the remaining debt on the property.
Key Steps to Follow
- Get a professional RICS valuation of the property.
- Confirm your exact outstanding mortgage balance.
- Calculate the net equity (Value - Mortgage).
- Determine the percentage share entitlement of each party.
- Calculate the 'Chargeable Consideration' for tax purposes.
- Consult a solicitor to formalise the Transfer of Equity.
Common Glossary
- Equity: The value of your home minus any debts secured against it.
- Joint Tenants: Owners have equal rights; the property automatically passes to the other if one dies.
- Tenants in Common: Owners can have unequal shares and leave their share to anyone in a will.
Frequently Asked Questions
Equity is calculated by taking the current market value of your home and subtracting the outstanding mortgage balance and any other secured loans. For a buyout, you then multiply this 'net equity' by the percentage share owned by the person moving out.
In England and Northern Ireland (SDLT), if the transfer is part of a divorce, dissolution, or legal separation court order, you usually do not pay Stamp Duty. However, in standard 'transfer of equity' scenarios, you pay tax on the 'chargeable consideration' if it exceeds thresholds.
Chargeable consideration is the total value given in exchange for the share. It typically includes the cash buyout payment PLUS the value of the mortgage debt that the remaining owner is taking over.
If the mortgage is higher than the house value, there is no equity to split. In this case, 'buying someone out' usually involves reaching an agreement on who takes over the debt or how the shortfall is settled with the lender.
No. While 50/50 is common for 'Joint Tenants', 'Tenants in Common' often have unequal shares (e.g., 60/40) based on their original deposit contributions or legal agreements. This calculator allows you to adjust the percentage split.
Common fees include solicitor/conveyancing costs (approx. £600–£1,200), valuation fees (£200–£500), mortgage arrangement fees (if remortgaging), and any early repayment charges (ERCs) from your current lender.
Yes, this is very common. You can apply for a new mortgage that covers the existing balance plus the cash buyout amount. This is subject to standard lender affordability checks and loan-to-value (LTV) limits.
Yes. Wales uses Land Transaction Tax (LTT) and Scotland uses Land and Buildings Transaction Tax (LBTT). Both have different bands and rules (like the Additional Dwelling Supplement in Scotland) compared to England's SDLT.
