I clean all shared areas of the home, cook occasional meals for guests, lawncare, maintenance, and shop for them (consistently provide milk, bread, basics etc)?

After reading many of the posts by broker/agents my takeaway is that honest, experienced, knowledgeable and competent agents are tired of the inexperienced, part time, or fly by night agents (fly by night: someone who enters as a salesperson for whatever is “hot” at the moment, be it real estate, oil and gas leases, used cars, etc) muddying the waters and causing them twice the work to close a transaction.  

There is a chicken/egg problem there because you need the business to need the warehouse and you need the warehouse to have the business.Also, I've thought about finding an accredited investor who would put the money into an oil well on my behalf.

I do most of the cooking so I try to cook decent food..

Hmmm, guess you didn't notice that @Michael Plaks is an "Enrolled Agent".There are hot dog vendors, there are fast food cooks, there are sit down resaurant cooks and there are fine dining chefs. 

Quote from @Nicholas Cook: If you have a tub/shower combo I would consider 2 things.

You will also need to install cabinetry and countertops, and you may want to consider adding a small stove or oven if you plan to do more extensive cooking in the space.

If not (ie two full-time working spouses) your only other option is going into land conservation deals, solar deals, or oil and gas deals - all of which have some risks.Explained in a different way...1) There are ordinary/W2/active income on one side.

I may even move into my little bungalow eventually when I get off the road working (oil and gas industry ) my W2 job.

If your investing with a company that practices witchcraft, maybe they can then turn that one property into 17 by cooking frogs.
