How much below market value should I offer?

Below market value means below market value, not below asking price. Asking prices are marketing, set by agents pitching for instructions, and a property listed 15% above what the street achieves is not a BMV deal at 10% off. Before sizing any offer, build the value figure yourself: recent sold prices for genuinely comparable properties, same street or immediate area, same type, similar size and condition, ideally within the last six to twelve months.

The median of good comparables is your anchor. Cross-check it on price per square foot against the property's floor area if you can get it, and be suspicious of your own optimism; the comparable that sold high usually had something this one does not. If you want the method in full, our GDV guide covers valuing from comparables step by step, and the same technique applies whether or not a refurb follows.

Every strategy has a maximum viable purchase price, and it is calculable. For a flip: end value, minus your target profit (most experienced flippers want 15 to 20% of the end value), minus refurb, minus buying, holding and selling costs. What is left is the most you can pay. For a rental, it is the price at which the net yield and monthly cashflow clear your thresholds at realistic rents. For BRRR, it is the price that leaves an acceptable amount of your cash in the deal after the refinance.

Worked flip example: end value £200,000 from comparables, target profit £35,000, refurb £25,000, all other costs £15,000. Maximum price: £125,000. If the seller is asking £150,000, your offer is 17% below asking not because 17% is a rule but because £125,000 is what the deal supports. If they will not move below £140,000, the deal does not work for you, whatever the discount looks like on paper.

This is the entire logic of disciplined offers: the maximum price is a property of the deal, and the discount is just the gap between that and the asking price. Sometimes a property at full asking is genuinely below market value because it is mispriced; far more often a 20% discount on an overpriced listing is still a bad buy.

Meaningful discounts are almost always paid for in something other than money: speed, certainty, or tolerance of problems. Sellers accept less when probate needs settling, a chain has collapsed, a landlord is exiting with tenants in place, a divorce needs finalising, or the property has issues that scare mortgage buyers, short leases, structural questions, non-standard construction. Cash or bridge-funded buyers who can complete in weeks are buying the discount with certainty.

Time on market is the visible signal. A listing at 90+ days with a price reduction has a seller already adjusting expectations; a fresh listing at a fair price rarely takes a low offer seriously. Auctions compress the same dynamics into a date certain, which is why they are where deep discounts concentrate, along with the problems that produced them.

Low offers get accepted when they are credible and explained. Lead with your position: proof of funds, no chain, solicitor instructed, flexible on completion date. Then justify the number from evidence rather than cheek, the comparables, the works the survey will find, the time the property has sat. Agents pass on offers with reasoning attached very differently from bare lowballs, because they have to sell the number to the vendor.

Expect to make many offers to win one; investors who buy well below market value hear no most of the time, politely stay in touch, and are there when the listing is still unsold six weeks later. Leave every rejection warm. And hold your maximum: the discipline that calculated £125,000 is worthless if you pay £138,000 because the negotiation developed momentum.
