So- if the tenants are supposed to pay those and they shred the bills- you'd never know until a lien is placed on your place.

That's a redundant question, because we all know it can easily be a $400 repair bill. 

You need to tighten us your insurance, electric, and water bills. $80 is certainly wrong for each.

Depending on billing, you might want to consider separate meters for each section if it is not already set up with multiple meters.On the metal frames, yes colder weather does not affect them as engineered systems are designed for specific locations, to account for snow loads, wind loads, etc.

one unit rented (the others - no history) high gas bills (adds to each unit a $150 (gas) and water $50 roughly) making it expensive to live there (I think). according to rent0meter I should be charging $725/ month, making it $925!

All discretionary purchases are on hold, and I'll be reviewing my recurring/subscription billings to cut charges that are no longer needed. 

The 20% reduction allows me to pay the mortgages and bills but eliminates most of my profit.

I'm with @Bill F. and having yield savings accounts.

The agent sent me a bill that is over 4% of the property price, and is asking me to pay for 100% transfer fees.
