You'll need a partner to go do the normal due diligence.

I'm looking for a partner to do a project and find out if we could make this work for investors.

This can be done but you need to have good partners that are local, get a rehabber and realtor that can walk the property and and give you a rehab estimate.  

I spoke to my partner about the issue and he suggested exactly what you stated.

You would be surprised at how many people out there that have a strong passion for real estate and would love to have someone under their wing.

Two partners and I paid cash for a property and for the entire rehab.

Guessing you're desirous to turn your Pittsburg dirt into profits, I think you're on the right track though will suggest strongly that you yourself or someone very knowledgable that you can trust and manage babysits the process down to keys in hand, as I assure you, dealing with contractors and all entities along the developer's path takes an entirely whole new layer of skin and nerve.

The two managing partners left egg on our face when they were placed into direct contact with the Sellers, and just disappeared from all communication when they claimed to want to schedule a walk through. 

If I buy a property with a partner under a 50/50 LLC, can I setup a separate DBA to receive rent checks that are simply passed through 100% to the LLC (e.g., there's no fee for the property management service)?

Charity organization will be 30% equity partner, whenever we sell the property or rent the property.Every property will be under an LLC, with 70:30 equity ratio.
