Valid considerations. I’ll think about how best to calculate stuff when costs fall below market rent.
That said imo fixing stuff is a capital expense/investment, not renter’s responsibility. It’s factored into rent, but I wouldn’t set a separate fund aside or anything. If something old breaks and I replace it, I’ve got the benefit of owning something new. (And the tax benefits of depreciation.)
At cost, if we include the interest accruing to the bank as a cost.
Maintenance/upkeep etc is my responsibility of course. Utilities split.
I won’t say everything’s to my liking, but I’ll sink spare cash into improvements.
