Commune/condo style living and fish tanks.

I'm just curious. Since the expense of getting a home seems like such a huge challenge I am thinking of moving into an artist housing complex.
Two towns away is a former mill building that has been converted into artist housing. I've been there before and toured the place. Recently I noticed one of the units was for sale and I started to have some ideas if this would be a good move for me.

I hate renting and have suffered from two abusive landlord situations now so I know I want to leave that behind for good. I find my apartment quite nice besides the issues like heating and that it's too small. It's the landlord situation that makes me feel tense and stressed.

They are thinking of converting a mill in this town into artist housing.
Does anyone have any experience with such housing arrangements and what their policies are on having large aquariums are or the floor strength of these mill buildings?.

Obviously I am very keen on bringing my boarded 150 with me when I move.
If I have to, I'd reduce down to my two catfish tanks. I'm sure some peeps here would understand that yes I'm partly going to choose future housing with being able to take my 150 gal with me.

That's what I was afraid of. I was hoping someone had experience with this type of housing situation.
I also want a small dog and this is another requirement when moving.
At least I know in artist housing, my studio needs would be fully met and I could return to my sculpture endeavors.
