If you are thinking about energy saving upgrades like new windows or upgrades to heating or cooling you can save a lot of money by working with their programs.- Think about the wiring.

. - You must have a good clean web site, a lead magnet (a form to get info from people in exchange for something cool), Facebook pixel and Google analytics at minimum. 

Very cool, totally depends on the build costs and if you can get a city to permit you. 

It would be cool to see the top 10 books in each category. 

what I did with some on my hard woods on a few of my properties I traded logs for finished flooring and had some really cool custom oak flooring made for my personal residence. 

This is cool to see, and inspires me.Im using a HELOC from my primary residence as well.

That is not cool to put other peoples money to learn on their dime.

And so is anything that will cash flow or even close to it, but I am hearing anecdotal evidence that the stuff at or above median is maybe now already cooling off.  

I am currently a student at GSU, but last year I bought a home to house-hack in SW Atlanta near the Beltline...really cool stuff happening in this market.

Let's assume that if you spend $80,000 now on geothermal and solar panels, you'll save $5,000 per year on utility bills forever, but if you spend $15,000 on regular heating and cooling equipment, you'll have a typical annual cost of $5,000 in utility bills.
