Though, you need to make sure you've done your due diligence and know your numbers going into the deal. 

This was an appreciation play with hopefully a cash out refi in the future but who knows when that will happen. 

I know people making $20k+ months couch flipping and investing in vending machines.

The reason I say this is that if you go to fix up the place and make improvements without getting the right contract into place, the seller could change their mind and keep the property. 

Let them know unless rent is paid in full, you will evict them and then start with the eviction-don't take any sob stories.  

I was not there, I don't know the details, all I have is the post from you.

I just wanted to know some issues you guys faced when you first started and any advice I should know or be prepared for.

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.

I want to know if you ever got a response 

I don't know any contractors yet, and even if I knew, I wouldn't be able to ask them for a quote for every single listing I analyze.I am very new to this community and I am very eager to learn as much as possible.
