I am not seeking to charge each tenant, only seeking to remotely monitor each buildings water usage to identify costly waste/problems early as possible.

We've installed the Moen leak detection device, which detects leaks both hot water and cold water, and monitors water usage and gives you weekly reports.

You could buy the meter, have a plumber install, you connect to computer, charge the exact amount of water usage. 

You can pay an annual fee if you want to have access and usage of CAR forms, but why would you when you can get free real estate forms from Firdt Tuesday. 

Of the remaining 25%, half are assuming risks inappropriate with the possible returns.  

@Brett Riemensnider You can claim expenses related to your rental property, even with a homestead loan, by allocating costs based on the 75% rental usage.

Everyone should do all of these for work or personal usage. - Before choosing a password manager, you should do some research on it.

A heloc is also calculated at it's Max amount usage even if not used during underwriting for a new mortgage.Cash out is tax free and it can be used as an "Asset or Liquid reserve" on new approvals. 

It’s unlikely to provide the immediate tax write-off you're envisioning.I’d recommend consulting a CPA to clarify your situation, especially if you’re splitting usage between personal and rental.
