Quote from Diamond Geezer:
good question, and a good short idea. Commercial real estate has a long way to fall. Don't know of any pure play unless you have access to credit derivatives in which case CMBX is the way to go.
VNQ is a reit ETF and this has the disadvantage of being a hodgepodge of several different property types. There are other REIT ETFs too.
I would suggest targeting industrial, office and retail REIT individual names.
CMBX hits right at the securitized commercial mortgage market which has a loooong way down to go. The same investment banks and institutional investors that gave us the CDO/sub-prime debacle are at the center of this process, and don't forget the rating agencies too.
To add fuel to this, commercial real estate developers and owners either directly or through mortgage brokers are putting together the financials to get these loans. Commercial loan brokers are in my experience let's ahem, ethically challenged. Same incentive structure throughout as for resi loans. It's harder to completely fabricate the data in commercial, no NINJA loans here but its a big enough debacle to ride down.
