how much would you pay?

I am looking at getting a house on a lake with a boat lift. I will be lliving there myself and would like to get a roommate if possible, but am not sure how easily that would be.

So my question is what would you pay monthly if you had access to a place to stay/live anytime you wanted and to ride an xstar anytiime you wanted? Like it would be your weekend home or something?

I want to do this to help with expenses. There are tons of houses on lakes around here and alot of them are pretty trashy and since i woiuld be living there fulltime i want to find something decent and because of that i know the price for a decent house will be more expensive.

Any thoughts or suggestions would be greatly appreciated.
