As a former active duty military member, I can assure you his global cash flow is borderline poverty level.

Let them know that you're a wholesaler and would like to get them some deals for their consideration.It might take you sometime to get started at this, but I can assure you, once you do and it takes off, it can be very rewarding. 

Called my bottom floor tenant and he assures me his sister is not living there.

(I won't get into the specifics of how exactly I'll be starting my real estate investing journey; just be assured that I have found a highly profitable niche in an overseas market that has very few downsides.)My question is: What is the most important thing, the most useful tip, the simplest fix, your two cents, etc. that you have learned either from personally investing in real estate or through your education and preparation to begin investing?

My main thing is, I need either guidance or assurance that what i am doing is good.

Neither is assured.

He assured me that unless he was enlisted prior to signing the lease and we had added a portion to the lease agreeing to terminate upon a move, that he had no grounds.

I would try to ask for contractual assurances where they agree not to build a new property right new door to an old store.

It may seem like it is easier on the seller but in the long run I think it will give a seller less assurance.
