The cons of selling your Facebook page include
One of the potential cons of selling your Facebook page is that you could lose out on potential earnings. If you sell your page for less than it’s worth, or if you sell to someone who doesn’t car for it as much as you do, you could end up regretting the decision to sell.
Another possibility is that, even if you sell your page for a good price, you could still lose out on potential earnings if the new owner decides to change the page in a way that doesn’t generate as much revenue. For example, they could decreases the frequency of posts, or stop running ads altogether.
Of course, there’s always the chance that the new owner will do a great job and the page will continue to generate income, or even grow at a faster rate. But there’s no guarantee, so selling your Facebook page could still be a risky move.
