My friend is moving in with her DP and plans to rent out her own house to another friend. I advised her to put it all on an official, legal, footing, because things like this have been known to break up friendships. She's happy to do this, pay tax on the rent etc. so it's all above board.
What are the pros and cons of different types of tenancy agreement for the two of them? She wasn't planning to insist on a deposit; I think she should, but am I right that she would have to lodge that with a deposit guarantee scheme? Is there only one of those?
N.B. She's lucky enough that it's mortgage free so that's not an issue.
TIA
