For financial reasons, my mum is being forced to sell her home. She is reconciled to the fact whatever value it's accrued she'll only be able to afford a small place. Her only comfort is the potential we may end up living nearby to eachother, because circumstances have left my OH and I in a similar situation and we're being forced out of London - so we're also moving. It's got me and my OH wondering whether we could somehow take over ownership because we can afford to pay off her mortgage; she would live with us and in 5 years the plan would be to build her an annexe to live in. She runs a business out of it currently and she'd still be able to run a smaller version of it, thereby enabling her to keep earning a living - as well as enjoying a higher living standard property-wise than the one she's currently facing. Does anyone know whether we could do this if she was up for it (which I think she would v seriously consider)? I've read something about buying it from her for under market value then she gifts us the rest of its market value - and that way we'd take over possession. Does anyone know what the tax law and other considerations are for this kind of transaction? Thank you very much
