Do I give up access to transportation, restaurants, cultural activities, doctors, emergency medical care, religious and business activities, vet care and maybe more, to live in the country on my ranch or on the beach in a beautiful country, or do I keep access to all those things and live in the city? 

The mirage of get into Real Estate Investing, make ton's of money, get passive, do nothing, sip cocktails on the beach and professionally vacation the rest of your days sounds great, unfortunately it's a mirage. 

If you are paying no rent in your parents beach house that could bring in a lot more to your family being rented as a beach house during the season.

Now as for what happens if a person who just lost a million+ dollar home just bizarrely says "nah, forget it, being a bum in a tent on the beach seems so much better".... well if ya knew the basics of Real Estate you'd know there is policy in place literally everywhere in the US for exactly that.

If you want land next to a river or the beach you can readily purchase it.
