We have a multi family rental unit which uses oil for home/water heating.Our tenants are responsible for purchasing their own heating oil.We are trying to figure out a way to determine when/if our tenant is running out of fuel.Our maintenance person has communicated that one unit has repeatedly run out of fuel, creating an increase service cost on their boiler.I know there are WiFi options to meter usage.

Where is your home located in Wilmington?

Generally speaking, per the NYC Zoning regulations, a R4B is limited to a maximum of 2-family homes.

We ended up going the HELOC route on that property for a few reasons. 1) the interest at the time was only 5%, which although seemed high, didn't matter too much with our potential property showing a 18% ROI 2) we leveraged a second home loan with 10% down for that new property, so our HELOC withdrawal was relatively small compared to what would be needed for a traditional loan on a rental. 3) I dont think I will see the rates in the 2% again in my lifetime, so figured I should hold on to that "free money" instead of selling it. 

Any tips if I need 10k to purchase cash or suggestions for loans?

If there are tons of homes with pools and wide open calendars yet the few places with PB courts are booked out, there's your answer.
