it seems some sit half empty , even a few minutes from downtown.thank youFilipe

On the other hand, if there were a lot of homes for sale, they were sitting on the market for a long time, and no one was buying, then you are in a buyer's market.

@Sam SchroederOh that's good, I'm sure you will gain a lot more advantage once you receive your license.I have noticed there are some properties that have been sitting a little over 2 months that make me wonder why they haven't sold and my newbie investor brain is skeptical.

You now have untapped equity in the land that is just sitting in the land, not being put to work for you.

Travis, wouldn't your property sitting vacant for 6 months make you a little worried?

My suggestion would be sit down with your bother and his wife.

This has "nightmare" written all over it.As @Erik W. pointed out, there are more than a few things here setting off red flags.With that said, regardless of whether this guy is on the up-and-up, it doesn't sound like you're actually in a position (from an education or experience) perspective to be able to help.Unless you have some previous capital raising experience and have a warmed up investor network (or you're sitting on a boatload of cash yourself), it's going to be a real uphill battle to get this thing funded.My biggest question is: Why is this guy coming to you (an admittedly new investor with no experience) to fund his deal?

I have done these as sit-down meetings and as drive-around including to my own properties or rehab projects.  

In these situations is it best to just sit tight for 4 weeks with my fingers crossed?

You should sit down with an expert on this topic.
