Buy to Let Building Insurance

Looking at a bunch of condos that are really cheap. I’ve already found out that no one/bank will finance them because:
1) no condo association
2) not owner occupied
3) those condos are usually in a building with 2 or 3 other units that are foreclosed, or bank owned, or short sale (brief, being sold at the same time)
4) no equity or low value for them to be worth their while

I have the cash to buy one of those units and was wondering what happens if I do and what may be some of the guaranteed or projected risks.

Say I buy one in a 3-unit building. Assume that the other two are bank-owned. Then:
1) how does water bill get paid?
2) how do taxes get paid?
3) there’s no condo association. do I still have to pay that?
4) how about insurance on the building? I certainly can’t assure it on my own seeing I don’t owe the other units.
5) once the other units get sold, do we have to set up an association and who’s in charge of that?
6) can the state come after my unit because the bank who own the other ones are not paying?

I’m going under the assumption that if those places are bank owned, then the banks have to pay their taxes and bills to the city so that they don’t get a lien on the units but I could be naive in thinking so.

I hope someone can help answer these questions.

Thanks!
All three units are owned by different banks and they are advertised as “bank listed foreclosures” or “REO” or “Bank Owned”
