Summary

People say “downvaluation” when the lender’s valuation comes back below the agreed purchase price. The practical impact is simple: your lender usually bases lending on their valuation, so you may have a funding shortfall.

This guide explains why it happens, what you can realistically do next, and how to model the deposit/mortgage maths.

Key terms (quick definitions)

  • Downvaluation: lender valuation below agreed price. See: Downvaluation.
  • LTV: loan-to-value. If the valuation drops, LTV can jump. See: LTV.

How it works

What the lender is doing

The lender’s valuation is primarily about risk: they want to know what the property is worth in the market so they can set an appropriate loan amount.

RICS explains that “down valuation” isn’t a technical valuation term — it’s the everyday phrase for the gap between a negotiated price and the valuer’s view of market value.

Why a downvaluation causes a problem

If you agree to pay more than the lender’s valuation, you have three basic ways to close the gap:

  1. Reduce the price (renegotiate)
  2. Increase your deposit (find extra cash)
  3. Change the lending (different lender / different loan amount)

Often, you’ll use a combination.

Worked examples

Example 1: The classic “shortfall”

Assume:

  • Agreed price: £300,000
  • Lender valuation: £285,000
  • Your lender will lend up to 90% LTV of valuation

Maximum loan = (£285,000 × 90% = £256,500)

If you still pay £300,000, your minimum cash needed becomes:

  • Cash needed = (£300,000 - £256,500 = £43,500)

If you only had £30,000 saved, you now have a £13,500 shortfall.

Example 2: Renegotiate to the valuation

Same numbers, but the seller agrees to reduce the price to £285,000.

Now the 90% loan becomes:

  • Loan = (£285,000 × 90% = £256,500)
  • Deposit/cash = (£285,000 - £256,500 = £28,500)

In this scenario, your original £30,000 deposit is enough again.

Example 3: You increase the deposit (and accept a different LTV)

You keep the price at £300,000, but you find extra cash (savings or a gift) to cover the shortfall.

If you add £13,500 to your deposit, you still buy at £300,000 — but remember: you’re doing that to satisfy the lender’s valuation-based loan limit.

Common mistakes

  • Treating downvaluation as “the lender being awkward” and not adjusting the funding plan.
  • Forgetting the lender’s loan limit is often based on valuation, not the agreed price.
  • Ignoring how the downvaluation changes your LTV band (and potentially your rate).
  • Switching lenders without budgeting the time impact.
  • Not getting advice on valuation vs survey (they’re different tools).
  • Proceeding without enough buffer for other buying costs.

What to do next

FAQ
Does a downvaluation mean the property is ‘worth less’ forever?
Not necessarily. A valuation is a view of market value at a point in time, based on evidence. But for your purchase, it matters because the lender bases lending on their valuation.
Can I appeal a downvaluation?
Sometimes you can ask the lender to review it with additional evidence, but there’s no guarantee. Your broker can usually guide the process.
Will another lender always value it higher?
No. Different lenders can reach different outcomes, but it’s not a reliable fix. Switching also adds time and can change rates/fees.
