On a VA loan anyone use an energy efficient mortgage?  

I'd like to improve our savings rate and get our household running very efficiently (time and money) so that there's more of both to spare for investing purposes. 

I agree with Aaron ... here is a fixed version of his link to the 2012 IRCand here is a link to the 2015 IRCMy main beef with the IRC and most codes derived from it, is they are light on energy efficient standards and design specs.  

I assume the new system is somewhat more efficient than the old, just by virtue of being new.

That was a pivotal point where I needed to figure out how to do things efficiently and effectively in order to take on more.  

But to make it efficient you need accounting software.  

Clean the darn heaters, you will find they are full of stuff and cleaning them will help with efficiency. 

I think the organization needs a complete overhaul and could be much more efficient than it is.

Where you will find yourself successful is providing support to your PMs and making them as efficient as possible so they can (comfortably) handle as many properties as possible.I don't know what market rate in your area is but your per door rate seems awfully low.

Buy at the right time to catch a wave of rent growth and force the value up through repairs and efficiencies.
