Right now there is so much opportunity, don't handicap your buying power 

The simple but not perfect math is that every 1% increase in interest rates translates to a 10% decrease in buying power.

I will increase my networking and knowledge power.

Solar loans are 30-50k and I believe that amount of money can be used to upgrade the homes bathrooms, kitchen or square footage instead of saving a few hundred dollars on power bill. 

The old gravity furnaces on the other hand, I don't hate (except fo the asbestos tape around the duct work and it's not usually a problem if you leave it alone)-- They are very inefficient (60%) but there is nothing at all to break, they work even in a power outage, and they put out serious heat.

So power those bad boys down without sacrificing your reserves. 

What I think is most revealing about the storyline is the power of the masses.

@Matthew Powers, this is referred to as your vacancy rate.

In other words, each series can have its separate rights, powers, duties for specific assets or liabilities and can have a separate business purpose.

Another part is local buying power.
