In short: An abandoned home is only a good investment if the numbers work: purchase price plus all costs must leave a healthy margin against the realistic end value or rent. Most failed projects underestimate works, finance costs and time. Work out your exit (sell, let or refinance) before you offer.
Worked example: a simple appraisal
| Item | Example figure | Notes |
|---|---|---|
| Purchase price | £180,000 | Auction or off-market |
| Stamp duty (additional property) | Check current rates | Higher rates apply to additional homes |
| Legal, survey and auction fees | £5,000 | Including buyer's premium |
| Renovation works | £55,000 | From itemised quotes |
| Contingency (20%) | £11,000 | For problems found once work starts |
| Finance costs (bridging, 9 months) | £12,000 | Interest and fees |
| Holding costs | £3,000 | Insurance, council tax, utilities |
| Total cost (before stamp duty) | £266,000 | |
| End value (comparable evidence) | £320,000 | From recent sales, not asking prices |
| Margin before tax and stamp duty | £54,000 | Deduct stamp duty and selling costs |
Illustrative figures only. Every property and area is different.
Exit strategies
| Exit | How it works | Watch out for |
|---|---|---|
| Sell (flip) | Renovate and sell on | Selling costs, capital gains or income tax, market changes |
| Let | Renovate and rent out | Yield after costs, compliance with the 2026 rental rules |
| Refinance (BRR) | Refinance on the new value and release capital | Lender valuations, six-month rules on some mortgages |
