Rent at the full market rate. Double rooms in the Bristol city centre and the surroundings go for £ 500 at least. The brilliant location and own bathroom would get an extra £ 50.

Subsidised rent would be for owner A or B themselves to live in the room. Or for renting out to partners/friends/people in need. Just need to make enough to cover their share of their mortgage.

Parking can be rented out for upwards of £ 100 p/m to residents in the same building or to outsiders who commute to the city centre and need parking.

Rental income for Room 1 and Parking goes to Owner A and rental income for Room 2 goes to Owner B. For extra rooms, add the split amount under Room 1 and Room 2 for Owner A and Owner B, respectively. E.g. to split £ 500 rental income for an extra room, add £ 250 to Room 1 and £ 250 to Room 2.
