Last year I started a goat milk lotion business that I was able to sell after 1 year for a decent profit.

Or perhaps milking you with repeated service calls?

milk is $7.00 a gal, drinking water in the store is $6.00 a gal. 

Just because someone is on section 8 doesn't meant they are a bad person...you just need to decide if you're going to be a landlord who accepts section 8 tenets or a "slum lord" who tries to milk every penny they can out of the system.

A contractor isn't needed until you have a job for them to bid.Gurus talk about "building a team" first because they know (I suspect) that most will spin their wheels doing that for long enough to milk them for a few thousand extra dollars in "coaching."  

If you're just recycling over wholesalers deals you have to ask yourself what value you're adding.  

All while working as humble teachers in a city where a gallon of milk can cost $8!

They pile up on everyone's desk, then eventually get dumped into a recycle bin.

I had a bright idea of selling the land.I recycled the same Contract Of Sale letter that the previous owner gave my dad and sold the land on payments for $22, 500 at 10% interest with nothing down. 

That is a good way to build your portfolio, but I would be cautious at this phase in the RE cycle.
