I think a reasonable, paid-off house could be almost as cheap as RV or van living.
Taxes and insurance aren't that much. A little sweat equity can keep up on maintenance. If bought correctly, you could sell for more than you paid.
The money tied up in a house isn't liquid, but if we're talking modest housing, it shouldn't be a majority of one's net worth.
I do think long term camping in a VW van would quite fun though!
Welcome to the club. I joined last August, but my savings haven't grown much due to buying a car last summer (used - low mileage). The last payment for the car is scheduled for tomorrow, then I'll belong to the true "no-debts" club.
Thanks for the kind words, all. It feels especially great coming from the wise folks here.
I bet there is a hell of a lot of people on here that are completely debt-free. Its probably like the INTJ concentration we have.
@BennKar: You joined the club today. Congrats!
