And a final note for comparison, although I grew up in a post 2000 open floor-plan house I also spent considerable time in my grandparents ~1916 home which was constructed by a wealthy engineer of the era.

The last place she gave me was her grandparents home.

, GRANDPARENTS (YOU ARE HUMAN I'M ASSUMING SO YOU SHOULD HAVE 4 TOTAL), AND GREAT-GRANDPARENTS?

My wife's grandparents hired Frank Lloyd Wright to design their home, which was built in the early 1950s. 

We rented one on Lido island last X mas  it was OK.. but being the grand parents we just snag the Master and let everyone else figure it out.. 

Maybe they raise some equity direct from immediate family (IE - mom/dad/sister/brother/grandparents/uncles/aunts/cousins), but the majority of the skin in the game is the GP's own.

I have inherited my grandparents home in Fort Smith, Arkansas.

I will say that I did manage to turn a couple grand of birthday gifts from grandparents, aunts, uncles, etc. into around 10k for them.  

Remember any money borrowed is deducted from your death benefit.Increases your premium.If you die your family gets your death benefit Minus your loan amount and all fees.It is to complicated and way too stacked for the insurance company for you to win.How many of our grand parents are living a comfortable retirement off the investment account of there whole life SCAM it is.....

I've drawn the new build for an owner-occupant to have a single family home but with the option of having a "tenant"/roommate or family member (perhaps in-laws, or elderly parent/grandparent, or a brother/sister, who wants private, separate living space, etc.) living in their own space with their own separate utilities.
