As long as the sale preceeds ( and by this I mean by as little as one minute - sign the settlement statement for your sale with one pen and then pick up another pen to sign the settlement statement for your purchase )the purchase you can identify, contract, put money down on - anything you want to tie up the new property ahead of the sale except take title to it.

Why would they be willing to let you tie up the property and attempt to sell the contract?

Save the money and keep the paint.Just make sure it ties in with the rest of your rehab and you'll be fine.I once bought a house with 11 different paint colors, but it was all done professionally and it tied together well.
