First I like to mention I have training in wholesaling but not alot of experience in wholesaling. Although I've done fix n' flip, buy & hold. So you may want to verify anything I say.
If your really want to Keep It Simple you can have your realtor do all the work for a flat fee. Then you don't have to worry about anything. Just let him know all what you want him to do & for how much. I like him to take pics, etc.
Do you have assignment contract? If so then I believe you would line up a buyer, have them sign the assignment of contract & then take both contracts to the title company. Also if you're not using a realtor I believe you can have a r.e attorney handle a lot of the 'heavy lifting' instead of realtor.
If you get in the habit of leveraging (assuming you have a little $ to spare) you will save a boat load of time freeing yourself up to do the higher end tasks.
Kinda like driving a car... do you need to be a mechanic to build it and or maintain it. You can if you want. But you don't have to.
Best,
Kel
