You can do either; get it under contract first then send to investors OR send the stats to investors to see if they like before contrsct. It’s really up to you.
Pros and cons to both. With the latter at least you’ll know if you have a buyer before going under contract.
Make sure you know your investors won’t go behind your back and contact the owner to buy direct.
Your wholesale fee should be subtracted from the 70% the amount is really whatever you desire. Just don’t overdo it.
Contracts are everywhere, I believe biggerpockets has some.
Whether it’s under contract or not doesn’t even need to be disclosed to the investor. Just show the stats if that what you chose to do.
Sometimes wholesalers will tell you straight up “assignment of contract”. Sometimes they just provide the details and you’ll have to dig to find out. Totally up to you.
Hope this helps. If you need a mentor, Adam Locklear is great he’s located here in Jacksonville FL but mentors virtually as well. Let me know if you want to get connected.
