What to do when you get an incoming Lead and no Buyer's list?

[Wayne Perry]

I am just getting started - Got a call the other day from a prospect that had a client in my city with two off-market properties for sale. I couldn't move forward because I had no potential buyer or any software to analyze the properties to see if they were deals or duds. I have figured out the marketing (No Paid Ads) well enough to get incoming calls. Just need to know how to make offers. What should should have been my next step? Anybody Please...

-Transactional Funding is not an option since I don't have an end buyer in mind-.
