Thanks for anyone providing useful feedback and/or constructive criticism. I understand this isn't typical and, as I said before, I appreciate it would have complications over a regular purchase, but am quite happy just to ponder and consider people's thoughts and opinions.
There's an absolutely perfect example currently for sale which is more or less already split. It's advertised as a 4bed main house and 3bed annexe, it actally says "lends itself to letting or annexe potential". It's kind of an L-shape with two seperate wings, each already with their own stairs etc. It would literally want a single door blocking on ground and 1st floor and maybe some insulation adding to the party wall. Also, it's been for sale for over a year so the seller might be open to it.
Let's say we found someone who was happy with the layout, and we agreed how much £££ we would both pay for our halves. I understand that we could make an offer on the house subject to planning permission.
My question is, how would this then differ from a normal house purchase? Does anyone have any experience with mortgages involving multiple parties? This seems to be the biggest hurdle, I'm sure the solicitors could sort the legal bit easy enough.
Thanks again
