Currently looking at the possibility of taking a year out of work to do some travelling and so would like to offer my flat for rent but the issue I have is that I used the Welsh government 'help to buy scheme' to purchase the flat and this restricts me from letting it out. So was thinking of offering it a reduced rate, maybe just to friends via social media and people at work to begin with, just to cover costs of the mortgage etc while I'm away.

If I was to rent it out to a close friend then obviously I wouldn't be so bothered about issues such as a contract or security deposit etc but if it was to someone else, maybe a friend of a friend or somone who works in my office, then I'd want an official agreement on such things.

I know I could get into trouble with help to buy and the mortgage lender for doing so but can anyone advise me here? Would I still be able to get a contract drafted up to cover the length of the rental agreement and deposit etc?
