What are the best ways to find cash buyers/investors?

[Joe Barty-King]

Hello, first post here. I've got my first deal under contract, but I'm struggling to find committed cash buyers/investors. I've been in touch with five people who have all seemed exceedingly interested ("Looking to buy this ASAP.", "I'm very interested in this deal.", etc...), but when it comes to sending over the assignment contract, I hear nothing back despite repeatedly following up with them.

I thought my deal would be very enticing for investors out there (potential for at least $75,000 to $100,000 profit after rehab), so I'm not sure what I'm doing wrong. At this point, I'm just looking for a small assignment fee so I can close my first deal and move on to the next one.

I did make the newbie error of getting the deal under contract before finding a cash buyer list, so perhaps that was my big mistake. How do you guys find reliable cash buyers for your deals? I've posted on Craigslist, Facebook groups, HouseCashin, LinkedIn, 'buy my house for cash' websites, etc...

Would love some feedback! Thank you very much.
