@Michael Swan here is how 25% of the residents are characterized by one research firm for the Santee zip.Our neighborhoods are filled with busy, married couple families who are working and paying down student loans and second mortgages.

Typically it's characterized by extreme savings and investing, right?

“The property types expected to provide the strongest inflation protection are the ones characterized by short-duration leases, or by rents linked to revenues.”

If there were a dispute between the members (hopefully that doesn’t happen with family), a rent-free arrangement could be characterized as self-dealing (taking personal benefit from company property).

The "price" of a piece of improved real estate can be re-characterized as the cost of attracting an owner, which takes into consideration all the neighborhood characteristics traditionally affecting the price of real estate.

@James Wise in relation to the video, what would you characterize this neighborhood as? 

Im curious what others knowledgeable about the guidelines say, but I do know in some cases this can be viewed as a single family with accessory unit (and may be characterized as a legal nonconforming use depending on the zoning and ordinance) and be conventional at an investor rate. 

If the OP is bringing more to the table, then it shouldn't be characterized as an equal partnership.

I would also characterize a seasoned investor as someone with some life experience in business and investment, perhaps with some road beneath their feet in life.  

Owner-occupants are not involved in the rental pool, and they often use bank financing to buy properties- that low cost of capital allows them to pay more for a home, which increases property prices(and the price/annual rent ratio.)In an area characterized by higher rental demand and fewer owner-occupants, investors primarily own the homes, and of course we investors usually pay less for "rental" properties than owner occupants pay for their homes.
