I think both of you might do well working with municipal planners, identifying blighted areas for renovation and rehabilitation.

I want to be appropriately aggressive about this, but I don't want to make any moves until I feel educated.

You can scan from a phone right into the appropriate folder.  

If I made a quick forum post mentioning that I was building a cash buyers list for the area and would love to hear back from anyone interested, would that be appropriate?

I would use Excel and categorize everything using the appropriate values from whichever Tax Form would be applicable to your situation (Schedule E, 1065, etc...)If you learn how to use some of the advanced Excel features like Pivot Tables and Filtering then you dont need anything more complicated if you are using cash basis.

First post, slack cut, appropriately.

If I do decide to take the fee(s), I am not sure how much would be appropriate to ask for (from the wholesaler only, not going to ask for anything from my friend, whatever they give is fine if anything)?  

If you are financing, you will need to verify where a CAP of 7 fits into the local market and whether lenders consider it appropriate for the market (if lenders expect properties of that type in your area to be going for a CAP of 8-9, then you'll have to contribute more out of pocket to bring them to the table.  

is appropriate because you need to know if it's a realistic price... but you get the idea.If you have not yet read “Insider Secrets to Financing Your Real Estate Investments”  by Frank Gallinelli download it from Amazon and read it tonight ;)Good luck!

You should consult with your CPA to ensure you are acting appropriately.
