I own a house, outright, no mortgage. It is worth around £140,000
DP owns a house, with a mortgage, which is worth around £450,000.
We have seen a property we both like and are keen to buy. Rather than going through the complexities of selling two properties, DP has suggested we remortgage mine with us both on the mortgage, sell his (houses here tend to go fairly quickly) and then both get a joint mortgage on the new property.
Are there any drawbacks I haven’t thought of?
