I'm scared by this proposition but the numbers (+1000 a month!)

On paper it's amazing proposition for investors. 

A quick glance at the San Diego market led me to conclude that cash flow was a tough proposition here, so I have been spending a good amount of time researching and networking in the Indianapolis and Kansas City markets. 

If I factored in a plug for maintenance/repairs and vacancy, it's very clearly a negative cash flow proposition. 

Depending of the amount of money investors want to bring in we will adjust our strategy.With more money invested we might aim for bigger lots/lands than just buying and holding single-family houses.This is a brief resume of what we are looking for and how we can help each other.If you know any investors that might interested by our proposition, please share this link to him/her.Thank you so much BP community!!!!

Think the OP's main question was whether or not the service had a tangible value proposition from a contractors perspective.   

It looks like you are looking for a partner to put up all the money which is tough to find because it would be all the same for that person to just hire the work done, in my opinion you may need to rethink the strategy to provide a more compelling value proposition 

Finding the lender that will provide the best terms for your loan is the primary value proposition of a commercial mortgage broker.

The second was a man propositioning me for inappropriate favors.

I found that having that background really helped to make my value proposition more convincing.
