. , until you own the property, you can't have them sign a lease.Make an amendment to the contract that current owner has them sign a lease that ends at midnight, day after closing so you can put them on your own lease.

And having served as attorney for two auction companies I gave you my opinion based upon that experience.Many times I got the call you made and I simply pointed the disgruntled buyer to the clause in the contract that says "AS-IS, WHERE-IS" and poof... the matter was over.

I believe my realtor wanted to do it after we get the home under contract.

I have posted this a hundred times:475.42-brokering without a license is a 3rd degree felony in FL.475.43-using contracts as a scheme or device to broker real estate is not legal.Brokering is the following--A BAR SALEAdvertisingBuyingAppraisingRentingSellingAuctioningLeasingExchangingFOR ANOTHER...so...this gentleman, even though believing he is doing stuff legally, is violating FL law.

I'm about to put my first wholesale deal under contract.

I have a property under contract and the seller is pushing back on some stuff. 

You inherit the lease and responsibility unless the contract states otherwise.

The seller had a contract a week or two ago for in the $120's and the financing fell through - so they are motivated to sell and will accept less than the asking price.Any thoughts/comments/ideas are greatly appreciated, thanks!

As an owner of a Property Management company, a Contracting company, and rental owner I can weigh in here. 

If laundry is on site find out if that is something that is contracted out.
