And if you wholesale, does the seller need to know that you are going to sell that contract?

So I would like to come up with some kind of contract stating that I agree to sell to them and they agree to buy from me etc.

Your purchase price should maybe be +/- $2000 from the appraisal price, but typically you should pay the appraisal value.Everything should be in-house - rehab work, management, etc - a turnkey company shouldn't be making you sign a contract for a third party management company because then they aren't really accountable to you long-term, the PM is.Beware of scarcity or scare tactics in sales.

Make sure you include zoning in your contract contingencies.

I'm looking for someone who can do assignments of contracts and double closings.

Make sure you draft the financing contracts since you want to avoid being locked in at a rate for longer than necessary.

My husband and are in contract for two SFH to buy and hold in the Charlotte area.

Just got my 2nd Birmingham property under contract and considering the BRRR strategy on this one.

I am a buyer and have a house under contract already. 

This would indicate 2 contracts between these two parties.
