I'm considering buying a second property for a DC to live in while they save for a deposit and increase their earnings to the point where they could get a mortgage. The plan is that they will repay me the stamp duty and legal costs on a monthly basis as "rent". I know that as this is income I will be liable to pay tax on it but how this works and at what rate etc I have no idea. I'm not even sure where to go for info - anyone out there who can point me in the right direction? No mortgage so no buy to let issues or repayments involved. The property will be in my name.
