Narrow it down to three and then really start to research them and search the threads here to find the best place for you.Feel free to message me if you want to meet up for a Jamba Juice or lunch sometime. 

Statistically, you are not going to get a massive family with 12 kids running around and spilling juice boxes on every square foot of your low-income property.

This is my only home, it may or may not be rented long term (pending long-term job relocation or not), and if the juice isn't worth the squeeze, I don't want to go forward with the headache.

Here's my draft list:1) Lawn maintenance - mow grass and trim back tree branches so that they're at least a few feet away from the house and HVAC systems outside2) HVAC - each HVAC unit has an electric compressor for cooling and electric forced air for heat - besides removing debris from the outside of each unit, I'm not sure if anything else is really needed (e.g. potentially clean condensate pans if they have buildup)3) Jet the sewer line - there are a few bellies in the sewer line but the tenants are not experiencing any issues as a result of that.

But what would i do if the tenant went belly up?  

Yes, an obstruction (belly, back graded etc) will let solids settle and will back up water. 

These deals are extremely few and far between, the seller usually isn't in a position to pay commission on the sale, and the juice is simply not worth the squeeze for a successful real estate agent who needs to make a living. 

What the seller appears to be doing is juicing the numbers for over market value to provide seller financing.With interest only there is no paydown of the note.

Welcome Andrea,Your drive to become financially independent rings a bell.  I

Reason being, if that sector is dying or company starts laying people off, moves, or goes belly up, then you still have enough residents and potential residents left in that market to keep occupancy up etc.
