I might be wrong but simple invoices to keep track should be sufficient. 

By small I mean in the $8 to $20 range.

If I am starting wholesaleing dino need a titleinf company and a closing attorney or would just the titling company be sufficient until I grow.

Of course, we don't know where you're located or what price range you are considering, but I would think you'd want a little more $$$15k is great and I commend y'all for getting that squirreled away, but that's only 10% down on a $150k house.

I think if it were me as the client I'd ask for a trial date range for the agreement, i.e. one week, and just explain to the agent that you want a chance to see how you work together.A fair compromise, IMO, would be that you'd use the agent if you bought a home you saw with them, but the option would remain for you to leave with no strings attached at the end of the week.

Depending on your location and the complexity of your site, this cost can range anywhere from $5,000 to $50,000.

If there is sufficient equity in the property you would also be entitled to be reimbursed for any property taxes you pay.   

A home ranging between 100,000 and 150,000!

We think, based on comps in the area, that our property will appraise for in the $310-$325 range. 

As for possible cash flow, I have looked around our area and the rentals cover a wide range of prices, so I'm unsure how much we might be able to pocket.
