My wife and I currently maximize contributions to our employers 401K plans investing $30K per year above the amount needed for employer matches.  

Any buildable land at a reasonable cost is more than an hour away from most employment centers (each way).

Today in most situations you don't have to talk to buyers employing these strategies because regular buyers are in such abundance to do deals.

Applicants do not qualify if they do not have employment or steady income of some sort.

To purchase these homes I have been using a partner who is willing to use his credentials ie. employment history, W-2's, Income, ect. for a percent of the profits, because I am unemployed and make ends meet solely through investing.

So make sure there are other big companies or plants that employ people in that area. 

For e.g. if the employer makes the employee sign that the employee will work for the said employer until death, you think that is a valid agreement in 2018.Still not sure why you even want such stipulation for your tenants, but again that's besides the point.

Your attorney or tax specialist should have the expertise to assist you in preparing the operating agreement correctly.If you are not self-employed I would encourage you to do so immediately.With self-employment you have immediate legal tax benefits for personal income retention just like Warren Buffett.To Your Successful Investing.It is a Terrific Day!!

Who is the main employer?

With tenants I can verify employment and references.
