As a wholesaler, should I expect 99% of my callers to want FMV?

[Patrick Philip]

That's all I've gotten so far. No deals.

[Bill Gulley]

Yes, any owner will want FMV, if they are of sound mind, dealing in good faith, they are entitled to a FMV. What might be negotiated in keeping with fair dealing will be the FMV if the property has been exposed to the market for a sufficient time.

A more motivated seller may take less than an asking price, they might give you a better deal if that benefits their position. You need to understand that position. 

"Deals" are not found, they are made!

If you know what makes real estate valuable, the different functions, then you'll understand how to make what you buy more valuable, then you profit even if you paid a FMV at that time.

Any owner has already been through the purchase side of a transaction, if you haven't, they have more experience than you do, you need to learn how to justify an offer, then you can make a deal. 

Good luck :)
