(Note however that the notice you posted concerns violations observed in March 2017.)

An extreme sellers market.

Some things you can do beforehand are: research the area to understand the local demographics and whether any similar type businesses have previously been approved, whether there are any currently in operation in the proposed area, if there are - evaluate what they are doing right or what they are doing wrong (how are they similar or dissimilar to your proposed property), reach out to the neighbors and get their input and try hard to get them on your side, reach out to the police department and listen to any concerns they might have, etc. 

My biggest concern is selling these solid, cash flowing properties and then not finding that next larger property.

Making money part-time in real estate is extremely difficult and likely to fail.

Asking someone to fund 100% of a deal when you haven't proven yourself, however, could be extremely challenging.

Our seller was interested in cash flow on a monthly basis and wasn’t concerned about overall profit margin as much.

While I've been intrigued by the ability to invest in notes from anywhere, it is what concerns me the most about making the leap into it.

Prices are still at a point where a good return is possible and there a lot of up and coming areas that are showing extremely good returns.

It is our responsibility to be extremely clear, back it up in writing, and never assume contractors should just know what we want.
