Commercial Real Estate Default Rates Over Time- Where to Find?

[Jonathan C.]

Hey guys- does anyone know a source of finding loan default rates for different commercial real estate asset types over time?

Example: mobile home parks, apartments, retail, industrial, etc

And, even better, that same information within asset types to the sub types- in retail for example I am particularly interested in neighborhood shopping/strip center default rates/performance over time.

Thanks for any help, Jon
