We are living in a topsy turvy world where housing you live in is not investment but a virtual cryptographic token is considered more useful and stable then solid real estate
Anything can be subject to volatility, the sub prime thing was mostly from political meddling. Anything useful can be invested in, cash is generally not investment as its just a form of debt. Bitcoin is at least an expression of work and unique placer in the blockchain, its debatable
I see House and lot as an investment though. if the location of this house has the access to everything from hospital, schools and supermarket.
It should be great and price shall appreciate in years to come. location plays a big factor when it comes to real estate. this is what i've learned from an agent i know because I've once processed it when my sister bought a house.
