What Does OIRO Mean? How Much Should You Offer?

Quick answer
OIRO means "offers in the region of". It tells you the seller expects offers roughly around that figure — a bit above or a bit below. It's a pricing signal, not a valuation, so you should still check what similar homes have sold for before deciding what to offer.
Common UK pricing terms
| Term | Meaning | What it usually signals |

| OIRO | Offers in the region of | Some flexibility either way |
| OIEO / OEO | Offers in excess of / over | Seller wants offers above the figure |
| Guide price | An indication of expected price | Common for auctions and unusual homes |
| Fixed price | Seller wants that figure | Less room to negotiate |

How much should you offer on an OIRO property?
Use the same process as any other offer:
- Find comparable sales — similar type, size and location, sold in the last 6–12 months.
- Check £/sq ft — is the OIRO figure in line with the local average?
- Factor in condition — deduct the realistic cost of any work.
- Consider demand — how long has it been listed, and how many viewings?
- Set your maximum — decide your walk-away price before you offer.
If the evidence supports a figure below the OIRO price, you can offer below it. If the property is in demand and well priced, an offer close to the figure is more likely to succeed.
Why agents use OIRO
Agents often use OIRO when a property is hard to pin to an exact figure, or to encourage offers without putting buyers off with a fixed number. It gives both sides room to negotiate.
