But, I wanted to avoid any question of unfair water usage and put the payment task solely on the tenant.

Or should I come up with a system on how the utilities will be divided every month so that the tenant is more mindful of usage? 

Hey,First time posting on BiggerPockets. Been voraciously listening to the podcasts. I got lucky buying a foreclosure which I sold for a stupid amount and put into a duplex. I am incredibly interested in ways to creat...

It's totally inappropriate for somebody to act that aggressively.He still has the keys.

What I do is when water bill comes I just text them a copy of it and charge them only usage part of the bill.

Next door neighbor was making inappropriate comments at our female tenants.  

Honestly i have no clue which angle he was ultimately trying to go at, but it sounded like he works with a lot of investors who own real estate that produce more deductions than they have in income to claim on taxes, the point he kept repeating was that you can calculate how much income on a property could maximize the usage of all your deductions, then either pay down to this point and maintain it, or refinance the property in a shorter mortgage to gain income and bring the level back up to this level every so many year or after paying it off. 

Title says it all... this is in my personal residence but I’ve found BP to be a more credible source for answers than searching the web.After 2 or 3 showers the water gets cool/lukewarm, not freezing and will stay that way, can usually get away with a shower in the morning and one at night without problems but if it’s the kids in the tub and a shower that pretty much uses it up.Typical usage, nothing too long, any help?

In Northern Indiana (Nisource), it used to be 20+ years ago (and I assume its still the case)  you would have to put a deposit down to cover the gas and electric distribution services, and you could get some credit back based on houses going into service with some assumed usage patterns.City run utilities and REMC's would have drastically different practices.
