Hello, we have seen a house we would potentially like to buy, but the estate agent says it “may” be difficult to get a mortgage as it’s a “concrete system build”. But they don’t seem to have any more information, like, the precise type of concrete system build (I believe there are a few types and mortgage lenders will lend on some but not on others). As the estate agent is being so vague, I don’t know where else I can go to get the information I need before potentially making an offer on the house. Does anyone know how I can find the information? Thank you
