Most flip deals that get pushed around look brilliant on a spreadsheet. The trouble is the spreadsheet is usually built on the best case: the lowest refurb cost, the highest resale price and a sale that happens overnight. A good flip is the opposite. It still makes money when things go against you. That is the whole test.
Here is what I look at before I would ever put a deal in front of an investor.
The flip equation
Every flip comes down to one sum. Resale value, minus purchase price, minus refurbishment, minus all the costs, equals your profit. The costs people forget are the ones that quietly eat the margin: stamp duty, legal fees, finance or bridging costs, insurance, utilities while the property is empty, and selling fees at the other end. A deal that ignores these is not a deal, it is a wish.
Below market value, properly understood
Below market value does not mean cheap. It means you are buying at a genuine discount to what the property is worth once it is finished, backed by real comparable evidence. A tired house on a good street, bought right, with a refurbishment that brings it up to the standard of its neighbours, is the classic West Midlands flip. The discount has to be real, and it has to leave room for profit after everything above.
A good deal survives a worst case. A bad one only works in a best case.
Why the West Midlands works for flips
Birmingham and the wider West Midlands sit in a sweet spot. Entry prices are still sensible compared to the South, there is strong and steady buyer demand at the resale end, and the rental market is deep enough that if you ever wanted to hold rather than sell, you have a fallback. Add ongoing regeneration and transport investment across the region and you have a market with genuine fundamentals under it, not hype.
Costing the refurbishment honestly
The refurbishment is where optimistic deals fall apart. The figure has to be costed by people who will actually do the work, not estimated from a desk. It needs a contingency built in for the surprises that every older property hides. If a deal only stacks without a contingency, it does not stack.
The exit is half the deal
People obsess over the buy and forget the sell. The resale figure has to be supported by recent, genuine comparables on similar streets, and it should be priced conservatively, not at the top of hope. A realistic exit that sells in a sensible timeframe beats an ambitious one that sits on the market for months while costs pile up.
Stress testing
Before a deal is good, it has to pass three questions:
- What if the refurbishment costs more than planned?
- What if it sells for less than the conservative figure?
- What if it takes months longer to sell than expected?
If the deal still works, or at least protects your capital, under all three, it is worth looking at. If any one of them wipes out the profit, it is not.
Red flags of a bad deal
- Best-case numbers with no contingency and no costs.
- A resale figure with no comparable evidence behind it.
- Pressure to commit quickly before you have seen the full pack.
- A refurbishment budget that was never priced by a real trade.
The bottom line
A good West Midlands flip is not the one with the biggest headline profit. It is the one whose numbers you can trust because they have been stress-tested to breaking point and still hold. That is the difference between investing and gambling.
