Buying below market value (BMV): how it actually works
Buying below market value (BMV) means paying less than a property is genuinely worth - not less than an inflated asking price. It is the foundation of almost every other strategy on this site, because a discount on the buy protects your downside and front-loads equity you can later refinance or sell into. The skill is telling a real discount from a fake one.
What BMV really means
A genuine BMV deal is one where the price is below the property's true open-market value, evidenced by comparable sold prices. That is very different from a percentage off an optimistic asking price, which is just negotiation. Real discounts exist because the seller is trading price for something they value more - usually speed and certainty - or because the property has a problem that scares ordinary buyers.
Where real discounts come from
- Motivated sellers: probate and inherited property, divorce, relocation, or the threat of repossession, where a fast, certain sale beats the top price.
- Fixable problems: poor condition, a short lease, damp, or non-standard construction that deters mortgage buyers but not a cash or refurbishment investor.
- Speed and certainty: a guaranteed completion to a deadline can be worth a real discount to the right seller.
Verify the value first
Discount is meaningless without an accurate value to discount from. Pull recent sold prices for genuinely comparable properties - same area, type and condition - and work in price per square metre to get a defensible figure. Only then is a percentage discount real. Anchor on the true value, never on the asking price, and be honest about the cost of fixing whatever made the property cheap.
Funding and the traps
Lenders generally lend against the lower of the price you pay and the surveyor's valuation, and many apply a six-month rule before they will refinance at a higher value - both of which matter if you plan to recycle capital through BRR. Beware the common traps: deals marketed as BMV against a deliberately inflated valuation, and sourcing offers that charge large fees for discounts that do not survive scrutiny. If a discount cannot be evidenced with comparables, treat it as marketing, not value.
Real vs fake BMV
A flat is on at £150,000 but comparable sold prices say it is worth £150,000 - a 10% off offer is just negotiation, not BMV.
A probate house worth £150,000 sold fast at £120,000 because the family wanted certainty is a genuine 20% discount.
The first builds no equity; the second builds £30,000 of it on day one.
