I'm looking for opinions on how much rent to charge/expect to pay in the following situation.
A family member is thinking of renting out some rooms in their house to another family member. I'm trying to help them decide on a fair deal for both of them so would appreciate your thoughts.
The people renting would be 2 adults renting a small double bedroom. They would also have a second bedroom of a similar size for their adult offspring to use to keep their belongings in and to sleep in as and when required, plus sole use of a further small home office/bedroom to use as a private living room. Shared kitchen, bathrooms, etc. Most bills included, except food.
What do you think would be a fair rent to pay and what would be your reasoning for it?
