Name changed for this; been here a long time, but this is quite outing and friends/family know my usual username..
Our house has a separate 'sort-of' flat; it's a lounge, bathroom, small bedroom and a kitchenette. Not its own front door, you to go through our house to get to it.
A retired relative has asked if they can live there. They have said that they would prefer not to have to cook for themselves but would join us for evening meal. They would do their own washing, cleaning etc.
I know we should ask for more than just the cost of food as there's actually shopping cooking storing food (and apparently he'd like to use his own wine glasses, so storing those as well, and whatever other kitchen stuff he decides he actually wants to keep).
We've an idea about how much rent we'd want to charge, and utilities, but if we were to go for this, I know there's more involved than just the cost of extra food. There's having to cook every evening, there's washing up, there's wear and tear on the washing machine and dryer, and quite possibly thing I haven't even thought of.
We were considering the possibility of ds living in that area when he's back from Uni (he's at GCSEs now).
I'm tempted to say no as we just haven't thought it through fully yet, but at the same time, we are desperate for money, and this would be very helpful.
