Hi,
We recently bought a house with an annex in the back garden. We'd like to AirBnB it, but already had great difficulty getting a mortgage for the property, due to living in Northern Ireland. The mortgage companies told us that we needed a commercial mortgage if we wanted to let out the annex, but a residential mortgage for the house, meaning we needed a mixed mortgage, but these don't exist in Northern Ireland! (We tried so hard - they're just not a thing) So we had to go with a residential mortgage and they made us promise we wouldn't let it out. Obviously we'd like to in the long run, but if the Tourist Board inspect it etc then they might highlight this as being an issue, and we'd like to remain legal.
Has anyone else got experience of letting out a self-contained annex in Northern Ireland? How did you get round the mortgage issue? Or if you're on a residential mortgage, did that come up as an issue? Thanks for any advice!
