Or hell, buy/sell a baseball card worth a lot.   

Breglio but he's on BiggerPockets I'm pretty sure and I've heard that he is a good guy for what that's worth. 

Say it'll be worth $600k when it's done and it needs $100k to get it there.

@Lavada Lindsey As @Jim Chesmore and @Russell Brazil already said there are so many reasons why the agent could be doing this it's not worth listing them all or speculating which one it might be.Just go straight to the seller yourself.

Would it be worth it to maybe buy one or two of these despite my preference to build on the relationship?

For instance, if you upgrade the AC to the tune of $8800 and you can increase your cash flow $4800 per year ($400 per month) that may be worth it.

NOT worth it!

I have no idea how much its worth due to having no experience in this area.

It's not that hard, but if you've never done it and are nervous, it's not a bad idea to hire a realtor to walk you through it.2) You pay a title company to research the title and get title insurance, same as if you used a realtor.3) Not really - but like you said, guidance and knowledge are worth a lot.
