How to compare 2 property deals side by side
Most comparison mistakes happen when investors compare one flattering headline against another instead of lining the same decision questions up across both deals. The stronger route is to hold the same standard on each side.
Worked example · illustrative figures
Two £180,000 properties, different cash commitments
A deliberately simple comparison before finance and tax. The £10,000 buying-cost allowance is an assumption, not a tax quote. Both examples use £45,000 deposits.
| Item | Example | Basis / comparison |
|---|---|---|
| Purchase price | A: £180,000 | B: £180,000 |
| Assumed monthly rent | A: £1,150 | B: £1,050 |
| Assumed works | A: £25,000 | B: £5,000 |
| Buying-cost allowance | A: £10,000 | B: £10,000 |
| Initial cash | A: £80,000 | B: £60,000 |
| Gross yield | A: 7.67% | B: 7.00% |
A adds £100 monthly gross rent but needs £20,000 more initial cash in these assumptions. Compare recurring costs, finance, works risk and evidence quality before deciding which result is more useful to you.
Work through the cashflowAsk the same deal-review questions of both deals
The cleanest comparison is often simple: what supports the case, what still needs proving, and what would happen next? Once those are stated for both sides, the better opportunity often becomes clearer without needing more theatrics.
- Hold the same price, rent, and works questions against both deals.
- Do not let one deal hide behind a nicer location story or prettier photos.
- Keep the outcome tied to action: shortlist, reject, or wait for evidence.
A deal with weaker evidence should feel weaker even if the headline return is bigger
One of the easiest ways to over-rank a deal is to ignore the quality of the inputs behind it. Rent that is still modelled and works that are still vague should directly soften the comparison outcome.
- Score the evidence quality, not just the end metric.
- Treat a cleaner, lower-drama deal as meaningfully stronger if the evidence stack is tighter.
- Use the pack or memo to make uncertainty visible rather than implied.
The point of comparison is not to reward the boldest story. It is to choose the deal that survives a cleaner read.
Comparing return without comparing effort is how weak deals slip through
Two deals with similar returns can be very different in operational burden. Works scope, strategy complexity, local constraints, and handoff friction all matter when choosing where time should go next.
- Compare how much coordination and proof each deal still needs.
- Treat execution drag as part of the return conversation, not as a separate afterthought.
- Ask whether the same capital and time could be used more cleanly elsewhere.
Pick the deal that deserves the next hour, not the deal that wins one metric
A side-by-side comparison should end with a clear ranking and the next move attached. The better deal is the one that deserves more proof and more of your time, not necessarily the one with the highest single headline number.
- State why Deal A wins or why neither deal deserves progression yet.
- Keep the next move clear enough that the comparison can be forwarded.
- Use proof cases and packs if the decision needs to travel beyond your own desk.
What is the biggest mistake when comparing deals?
Letting one flattering metric dominate the whole decision. A slightly lower return with cleaner evidence and lower friction is often the better opportunity.
How many metrics should I compare first?
Start with a small set: rent truth, price view, works drag, open checks, and next move. That is usually enough to show which deal deserves more time.
When should the comparison be turned into a Deal Pack?
When the ranking needs to be shared, defended, or acted on by someone else. That is when the comparison becomes more than a personal note.
