Maybe your aim is to get the lot tarred, painted and coin-op or hire security/ attendants then flip the business / property for a profit.

Throwing in one more Abe Lincoln coin here...if you're an investor, visit the market you're investing in, create one on one relationships with your service partners on the ground, start you're own RSS feed on all things on the city from jobs, crime and fiscal health of the city and state (reason I stay faaaaaar away from Chicago and Illinois).

I know there are two sides to every coin and I appreciate you looking out for me.

This fortress makes lawyers resistant to take on the case to sue you.The other side of the coin.

Do others include washer/dryers or a shared coin-op?

There is a column for other income usually a coin operated laundry or a garage.

I too am on the road to FI - I am turning 34 in April and would like to by 38 make more from real estate than I do my W2... work 2 more years just to build up a bit more of a financial runway (@Scott Trench) I think coined that term in Set for Life.

"Buying under market" was pretty much coined by gurus, easy to understand, sounds sexy, and then they add "and made $25,000 that day!"

In any event, I have someone who wants to see it so fingers crossed not only do I learn book knowledge here but maybe get a few coins out of the deal as well. 

I am a commercial broker and investor myself so my situation is different than the typical newbie agent hustling to make a small coin to pay their bills.
