Shortcuts to Analyze Value-Add Apartment Deals?

[John Casmon]

I've seen plenty of shortcuts to analyze apartment deals, but not quite for value-add strategies. 

It takes me at least an hour to properly analyze a value-add apartment deal, and I'm curious if others have come up with shortcuts to determine if a deal really warrants the full analysis. Is there a way to quickly tell if a deal warrants that hour long investment? Is there a key metric that you look at to determine if a deal is worth more of your time?
