Part of your return will be based on your skill in speculation.

Do you have the time and skills to track every dime so that each partner get his/her appropriate share?  

Managing people, problems and a day job is an art.  

Hiring people that are experts where I am not, and compliment my skills are important. 

Of course, people management skills are also extremely important in this biz, being a strong and effective manager of your crew is so important in not only serving the customers properly but running efficiently and getting things done during the shifts so the crew isn't there too long after closings, thus once again factoring into saving you some money on your labor costs.

What do they offer, at what skill level, what services are included, and at what rate?

Think limbo here, and "how low can you go" This is both art and science as too high is not the best deal you could get and too low insults the seller, making him hard with which to negotiate.

A good way to do this is to offer them a higher return than they invested for initially.Professional people such as doctors and dentists,or other skilled professionals have a tendency to invest in groups.

I am picturing using my current single-family deal finding skills to list and sell a few high-value commercial properties per year and collect some fat commission checks.

At this point, I strongly believe it is best to avoid dispute with tenant by having good management skill, inter-personal skills, leadership skill, good ethic, good judgment.I'm sure I will learn more lessons in the future.
