Castle Trust Bank has dropped the need for a physical valuation on some standard buy-to-let cases, allowing automated valuation models to be used on eligible properties worth up to £750,000 at a maximum 65 percent loan to value.
The change applies to standard residential buy-to-let houses and single flats, and it gives landlords a quicker route through underwriting where the case is straightforward enough to avoid an in-person survey. That is a timely move in a market where product pricing can still change quickly and delays can upset refinancing plans.
For landlords, the fresh angle is not just convenience. It shows lenders are competing on speed and process as well as rate, especially for cleaner remortgage and purchase cases where time lost on valuation can mean missing a deal.
Faster processing is becoming a lender selling point
Castle Trust said the automated route will sit alongside its wider lending process rather than replace physical valuations across the board. In practice, that means standard cases may move faster while HMOs, mixed-use assets and other specialist properties still face the usual checks.
That matters because a growing share of landlord borrowing is now about execution risk rather than simple appetite. Landlords trying to refinance or complete before a product is pulled are watching not just headline rates but also how quickly a lender can get from application to offer. Landlord Knowledge has already covered buy-to-let lenders cutting rates before the remortgage rush and mortgage choice widening as two-year fixes fall again. The latest Castle Trust move points to a third battleground: process speed.
Castle Trust said eligible cases will avoid the delay and cost of a physical survey, which should appeal most to landlords with plain-vanilla stock and clean application files.
Standard cases get easier, but specialist landlords still wait
This follows Landlord Knowledge’s recent report on the FCA’s mortgage rule review, which looked at how lenders and regulators are weighing access and friction in the borrowing process. Castle Trust’s latest change suggests some lenders are now trying to remove delays at the operational end of the journey rather than only compete on price.
There is still a limit to how far that helps. Landlords with more complex portfolios, unusual ownership structures or non-standard properties are unlikely to see the same benefit. In that sense, the move could widen the gap between straightforward cases that get rapid treatment and specialist deals that still take longer and attract closer scrutiny.
That is the practical warning hidden inside the announcement. Faster automated valuations are good news for a slice of the market, but they do not mean underwriting has become looser. If anything, they show lenders are separating standard business from more manual, case-by-case borrowing more clearly than before.
Castle Trust has outlined the change on its property finance pages.
What this means for landlords
- If you’re refinancing a standard property: a lender using AVMs could cut delay and reduce the risk of missing a time-sensitive deal.
- Watch for: whether more lenders copy this move on low-LTV standard buy-to-let cases over the summer.
- Bottom line: faster processing is becoming part of the landlord mortgage offer, but the gains still look concentrated in simpler cases.
Editor’s view
Castle Trust’s move is useful because it targets a real landlord pain point rather than dressing up a small pricing tweak. But it also shows how the market is splitting: the easy cases get quicker, while specialist borrowers still pay in time if not always in rate.
