I find I usually need to go through about 100 leads to find 1 with enough money.

Aside from that and other scenarios that lead to cash flow negative real estate, and assuming no changes in employment, DTI should never be an issue with a real estate investor.

I'm a wholesaler here in Texas and I've been told that the tax delinquent list is some of the best leads if you pull the ones who haven't paid their taxes in over 2 years.The problem is that they're not located in Texas (they're located in North Carolina) and I'm wondering if the same laws and scenario would apply in this state if I pulled the list of tax delinquent properties over 2 years. 

That lead to lots of podcasts, and, it seems, all roads lead to "Rich Dad, Poor Dad" and BiggerPockets.

So far I have liked having a separate deal finder and property manager, so that I can have the opinion of multiple people before purchasing a deal.In your experience, is it better to keep these roles separate?

Of course you would have to "sell" the big guys and lead them to believe that you are fully committed and in it to win it, despite the fact that you have another vision. 

It is critical that you complete all of it, including the lead based paint disclosure and any other state specific disclosures.  

For me the easiest way to understand the role of a developer is as a bond maker and seller.

As a wholesaler, your role in the big picture is to identify and secure a purchase opportunity that you can deliver to your buyer, so that THEY CAN MAKE MONEY.

This LLC would need to have its own separate EIN and bank account as well as an operating agreement which defines the roles and responsibilities of the investors, manager(s), etc.
