What to Do If Your London Appraisal Comes In Low
Practical next steps for London buyers and sellers when a lender appraisal is below the purchase price — ROV, second opinions, and negotiation.
A low appraisal in London usually means the lender
A low appraisal in London usually means the lender will advance mortgage funds based on the appraised value, not the purchase price. The gap becomes the buyer's responsibility unless the contract is renegotiated.
First step
First step: ask the mortgage broker or lender what reconsideration of value (ROV) process is available. Most lenders accept additional comparable sales, factual corrections, and permit / renovation evidence.
Second opinion
Second opinion: a fresh appraisal from a different qualified London appraiser may be warranted where the first was a desktop or drive-by product, the comparables look weak, or the property has features (Century detached with legal secondary suite — refi with income-approach overlay) the first appraiser may not have credited.
Balanced seasonality but individual submarkets can thin out
Balanced seasonality but individual submarkets can thin out — appraisers time-adjust across a 90-day window off-peak. A low appraisal in a thin-comparable window is not always wrong — it may reflect the local sale pool.
Treat the appraisal as data, not a verdict
Treat the appraisal as data, not a verdict. Rebuttals succeed when they include better comparables and specific factual corrections, not when they argue about the value conclusion in isolation.
