Is this a legit situation or can I fight this?

But, most legit GC's with insurances and references can get approved.

Would this be legit?

I paid $1,000 for the contract, seemed legit and like a good investment.

you can check your local property appraiser/tàx collector website usually to see what taxes are and in a rapidly appreciating market, yes, taxes are going up so it could be legit.  

Are there any that are legit?

If its legit, he deserves his fee for finding and negotiating the deal, IMO.

Casinos maybe not haha

I’m wanting to know what all is needed to make the deal legit.

Quite a few investors used their RE license to list short sales below market on the MLS, then ignored legit offers to make it look like they weren't selling, and then had their own company make a low ball offer in order to truly defraud the bank.
