I would share the cold hard tenant ledger and let the next LL decide how to interpret it.As far as lying, acting as someone's accomplice in a fraud make you both rather bad people and sort of undermines your stated reason for looking to do this in the first place.

Having you tenant living in extreme heat or cold is a big No No!

Our teams cold-call and find a lot of good deals in the college towns and outside of campus.

Here are some specific questions i have:1. are there certain locations where revenues may be impacted by seasonal weather changes, like for example heavy rainfall for 1 out of 3-4 months will drop revenue significantly, or excessive heat/cold for seasons will bring significantly less customers?

When I started, these forums, doing research online, and cold calling really helped me find some of the bigger investors in my market. 

Examples:- Brokers- Cold Calling- Networking- On Market

cold calling What was the outcome?

Hot water is usually separated it is just the cold water that is often not.For a very large building a flat fee is the move because the back billing and tracking of who paid for what would be hectic, but for a small MF like a duplex it is very easy.I split the bill by the fractional amount of people who live in the unit.In other words, the amount of people that live in the unit divided by the total amount of people living in the builidng.So if there are 3 people upstairs and 2 people downstairs.the upstairs pays 3/5 of the bill, and downstairs pays 2/5.No need to separate anything, you know the tenants will cover 100% of the bill and this approach is fair. 

Networking and cold calling/texting is what's always worked for me.
