What happens if your remortgage valuation comes in lower than expected?

A down valuation happens when the lender’s surveyor values your home for less than you expected, less than an online estimate suggested, or less than a previous valuation. This matters because your loan to value, or LTV, is based on the mortgage amount against the property’s value, so a lower valuation can push you into a higher LTV band, change the rates you are offered, or reduce how much the lender is willing to lend.

Why does a valuation come in lower than expected?

Several things can cause this. Online estimates and even estate agent figures are not the same as a professional valuation carried out for mortgage purposes, and surveyors often take a cautious view, particularly in a slower or uncertain local market. Specific issues with the property, such as its condition, nearby comparable sales, or unusual features, can also bring a valuation down. This is a normal part of the remortgage process and happens across all lenders, not something specific to any one type of applicant.

How a down valuation affects your loan to value

Your LTV is your mortgage amount divided by your property’s value. If your home is valued lower than expected, your LTV rises, since the same mortgage amount is now a bigger share of a smaller figure. Lenders price and set criteria in LTV bands, often in 5% steps, and lower LTV generally widens your options. Our guide on how LTV affects a bad credit remortgage explains this relationship in more detail.

What are your options if the valuation is low?

• Ask about a valuation review. Some lenders allow you to challenge a valuation with evidence such as recent comparable sales, though this is not guaranteed to succeed and not every lender offers it.
• Reduce the amount you want to borrow, if that is workable for you, to bring your LTV back into a band the lender is comfortable with.
• Consider a different lender, since valuations can vary, though this means another application, another valuation fee, and usually another credit search.
• Stay with your current lender via a product transfer, where a valuation is often not required at all. Our page on product transfers with bad credit explains when this route can avoid the issue entirely.
• Wait and reapply later, if your circumstances allow, particularly if the local market or your mortgage balance is likely to improve your position.

Does adverse credit make this worse?

A valuation reflects the property’s market value and is not connected to your credit history. The two checks happen separately. Where it can compound difficulties is if you already have less room to manoeuvre because of a CCJ, default or other credit issue narrowing your lender choice, and a down valuation then removes another option. Our page on remortgaging with a low credit score covers how lenders in this part of the market weigh up applications more broadly.

A worked illustrative example

These figures are for illustration only, not real market values. Suppose a homeowner expects their property to be valued at £250,000, based on similar homes nearby, and wants to borrow £175,000, which would be 70% LTV. If the surveyor instead values the home at £220,000, the same £175,000 mortgage becomes roughly 79.5% LTV. If the lender’s range for that borrower’s credit history only extends to 75% LTV, the down valuation alone could move the application from within range to outside it, even though nothing about the borrower’s own finances or credit file has changed. Reducing the amount borrowed to around £165,000 would bring the LTV back to 75% in this illustration, which shows why some people choose to adjust how much they borrow rather than start a fresh application elsewhere.

Common mistakes when facing a low valuation

• Relying only on an online estimate before applying. Online tools and even estate agent appraisals are not the same as a professional mortgage valuation, and treating them as certain can lead to a plan that assumes an LTV that does not hold up.
• Not building in any margin. Applying at the very top of an LTV band leaves no room for a valuation coming in even slightly lower. Where possible, leave some margin, particularly if you are already relying on a specialist lender’s LTV limit because of adverse credit.
• Reapplying to another lender without checking why the valuation was low. If the issue is specific to the property, such as its construction type or condition, a second valuation from a different surveyor may come back similarly low.
• Not asking about a product transfer first. Because a product transfer with your current lender often does not require a new valuation, checking this option before applying elsewhere can avoid the risk of a down valuation altogether.
• Panicking rather than reviewing the numbers. A lower valuation changes the LTV calculation, not necessarily whether a remortgage is possible at all. Working through the table above with an adviser can show whether a smaller adjustment resolves it.

What this means if you are remortgaging with adverse credit

If you are relying on a specific LTV band to make a bad credit remortgage work, for example to access a particular specialist lender’s range, it is worth asking in advance what happens if the valuation comes in lower than an estimate suggests, and whether there is any flexibility in the amount you are looking to borrow. If a down valuation does derail an application, our guide on what to do if your remortgage is declined and our page on releasing equity with bad credit set out some of the next steps to consider.
