The $900 feels clean but it disappears in a week. The two zip codes you've been targeting for six months have compounding value that the appointment fee doesn't even begin to price in. You're essentially selling market intelligence for $300 a pop, and that's the part that stings later, not the liquidity.
What I'd actually do with an active raise: wholesale the one deal outside your target geography, full stop, take the $300 and move on. For the two you care about, go back to those sellers with a longer option period, 60 to 90 days, and use that window to either close the raise or find a JV partner who puts up the capital while you control the deal. I've structured three deals this year exactly that way coming out of a capital-light period, and the option costs me almost nothing if I've already built the seller relationship through the appointment. You don't have to choose between liquidity and the zip code if you buy yourself time instead of selling the lead.
