When is a family visit more than a visit?

When is a visit more than a visit? When your relatives visit how long or how many days do they stay on average? How many days do you believe the average visit last before the guest go home? Does it make a difference if the “visitor” is children, parents or siblings? If your relative wants to visit until they get situated or ”straightened out” how much time would you give them to ”visit”? And would that amount change if they had the opportunity to move on but simply passed on the chance because it would cost more than they wanted to pay but they could have by tightening their belt a little? Would being pregnant or with a small child change the game? What if you could not have people living there which was not on the least or against HA rules, does that change the deal? If they don’t pay and very rarely help out with anything make you figure different?
