Run the numbers Mary.  

I have 28 units now and it's time to improve my systems and look for better ways to run credit, etc.

We'll need to do something if we ever want to sell because we may run into the same issue these owners are with financing a property with a mobile home-as buyers we couldn't get financing so they were limited in who they could sell to. 

I figure some of the properties that I run into ppl may be underwater on their mortgage.

It was run down and boarded up. 

I run a successful interior design business and some of my clients are developers. 

Can anyone recommend some good books that discuss organizational leadership and how to properly run/establish business operations. 

In my opinion, yes, it can be done, but you're looking into a bigger mess as far as the government is concerned.Lets preface this with I don't know exactly how this works either, but after a certain amount of people are involved you have to report as a Real Estate Investment Trust (REIT) and have to file extra forms related to your business and also after a certain threshold you also need to report members and their distributions to the Securities Exchange Commission (SEC) so they know as well.Being young (as am I) you are going to run into a lot of dead ends trying to apply for a residential loan with a business name.  

I know there are tons of productivity apps out there, but I'm curious which one(s) you find most useful for running a two-person real estate investing team.Thanks in advance!

@vladimir valladares,Or you can  just tack on the typical Agent commission to the sales price and run it through the brokerage office.No problem there. consider it what it is, an off market transaction.
