Hi Raden Mantuano, it sounds like this may be a REO agent, these houses are probably foreclosures which means the seller is a bank. These can be difficult to wholesale because they will not allow assignments, and if they are listed that means everybody who scans the mls will be all over it the minute it is listed.
The pros are if you can build a relationship with an agent by closing on a few deals, he may throw you a bone in the future by giving you a heads up on a property before it is listed.
The other thing I would say is that most motivated sellers don't have time to list their property and involve an agent, they need to sell now! I would focus on creating a marketing strategy to get as many motivated seller leads as possible if you are just starting out.
I think it would be a good idea to check out his other listing and ask some questions. Find out if it is bank owned or private seller, ask about the market, it never hurts to network.
