I am still on the side that thinks the 45 days should be based on if your account is active not if you signed on. There can be times when there are issues where you cannot connect to the game but your subscription can be or has been paid for. I have had instances where factors such as my internet provider or psn was preventing me from logging on but like i said my month was still charged. With rent who is to say that it will not have a negative impact on the game economy and people will either not buy things off the market board, raise their prices even higher, or undercut everything.

The only thing that can really fix this is adding more houses or ways to use housing features.
