Your broker applied for an HMO mortgage. The lender said no. Here’s why. Got a call this morning from an HMO investor in a panic. Their broker had put in an application for an HMO mortgage on a property they were buying to convert into a 6-bed en suite HMO. Declined. And honestly, it’s an easy mistake to make if you don’t live and breathe this stuff. The property hadn’t even been converted yet. It was still a standard C3 sitting there. An HMO mortgage needs the HMO to actually exist first. So their next question was, “can we just use a buy-to-let instead?” Also no. Because you can’t convert a C3 into a C4 HMO during the term of a standard mortgage. The lender won’t allow it. What they actually needed was a refurbishment bridge. A bridging loan with stage-release funding built in, so they could complete the purchase on day one and draw the conversion costs down as the works progressed. But if your broker doesn’t specialise in HMO finance, this is exactly the kind of gap that causes deals to fall over. If you’ve got an HMO project coming up and you’re not sure what finance you need at each stage, send me a DM. I’ll give you a straight answer.
