Returns are before tax. Selling costs come out of sale proceeds, not your upfront cash.
Not financial advice. For educational purposes only. Refurb budgets, holding periods and bridging terms vary widely, and figures here are pre-tax. Verify costs, finance terms and your tax position with your broker, builder and accountant before committing.
A flip is won on the buy and the budget. The headline “bought for £120k, sold for £200k” looks like an £80k win, but buying costs, the refurb, months of holding costs, bridging interest and selling fees can halve it. The number that matters is the net profit, and whether your profit-on-cost gives enough margin to absorb overruns.
