He suggested I share some background on how our system came to be and why we do things the way we do.

I've not heard of Investor's Edge, but definitely look at the backgrounds (resumes/Linked In profiles) of the principals to see what they did in the past. 

Anyone who is interested in investing in a syndication will ask about your background, and if you cannot show them that you have a track record of meeting/exceeding return projections, they will likely pass.

If someone applies, how would you suggest that we run credit and criminal background checks on them so I can see if they are someone I would like to run credit on? 

The background: My husband is a professional homebuilder and we'd like to have more flexibility (we have several very young children) in his workday. 

I don't charge an application fee but I do have the tenant pay for their background check. 

I've been around for over 30 years and I have a formal credit background from 2 of the largest banks in the world.

- I use an online credit/eviction/criminal background check service, should I expect them to be able to fill out and pay via the online service?

Be sure to run a thorough background check!

With a background in retail and customer service, I believe I possess skills that could be valuable in this field.However, before diving headfirst into this new venture, I want to make sure I have a clear understanding of what exactly co-hosting responsibilities entail.
