@Dylan Gelbard I have no issue with wholesalers. I have been the end buyer in wholesale deals, and the private lender to the end buyer. So I'm very familiar with the process. It may be as simple as you described, but it's not as easy as that. If it were, everyone would be doing it (not just trying to do it).
In my experience, most wholesalers struggle in one of three areas:
#1 - Trying to find deals
#2 - Trying to find end buyers
#3 - Trying to find one or both of the above consistently
Now, you've managed to do #1 and #2, which is actually a LOT farther than most people trying to be wholesalers get. So congrats for that. Seriously.
However, before you celebrate too hard, re-read the last sentence of your post...you just did one. Most people who are trying to become wholesalers are trying to make a job out of it and want/need consistent income so they can supplement (or even replace) their W2 income. One deal is a good start, but it's nowhere near enough to do that. It's a bit like saying "I don't understand why playing in the Major Leagues is so hard. I just hit a baseball."
By no means am I trying to diminish your success with this one deal, because - like I said - you've done a lot more than most who try to get started. But now it's time to focus on #3 on my list above.
Best of luck to you.
