Seller calls you. You ask all the right questions. You determine that the seller is really motivated. You know his asking price and the least he would take on the house. Make an appointment to go see the house in person. If the deal is not even worth considering, hang it up, but if it has a chance, go from here.
You then perform your due dillegence, research the house, the ARV, taxes, neighborhood. Determine a good ARV at this point.
Then you go visit the house and look around, determine the fix up costs. Tell the seller you will have an offer in x amount of time.
Do your math here, take the good ARV, put in your numbers 70% ARV (or less) minus repairs and your assignment fee, this is your offer, offer even lower for some wiggle room.
Make your offer either by letter of intent or fill out a contract for them to sign.
They accept the offer, GREAT!!! Send the contract and any earnest money (if you are putting earnest money) to the title company and open title.
Now to get it sold.
Market your deal, send it to your buyers list, put it all over the internet, put out signs, however you market your deals.
Buyer calls or emails you, is interested. Show him the house. He wants to buy at the price you want.
Get him to sign the assignment contract with the amount you are assigning the contract to him. Give the buyer a copy of this contract and the contract between you and the buyer. Collect earnest money from the buyer as well!!!
Send the assignment contract to the title company along with seller and buyer's contact information. Tell the title company to close as soon as possible.
Pick up your check after closing.
This is wholesaling in its simplest form.
