Hi @Joseph Pond, if you provide more specifics that will help with more efficient recommendations. 

Mini-splits are less expensive and can be more efficient as well. 

I find that duplexes don't work very often because there's little efficiencies of scale.Your CapEx and Repairs are a little low.

However you plan to get into real estate, find a way to begin with a model you can scale efficiently.

It’s a real balancing act between specializing for maximum efficiency and profit, and investing outside your speciality for new opportunities education, knowledge and experience.  

They are claiming it would be more cost efficient to use a fireplace than a heater (not sure if that's true in their area). 

Some examples of democratizing Real Estate: online listing sites, online fundraising sites, online bidding, crowdfunding, anything else that lowers the barrier to entry.As technology continues to improve and be utilized in the real estate industry, prices will become more efficient, or closer to the true intrinsic value.

Energy efficient.

I hope there is a good decrease in cost as new units are high efficiency BOSCH boilers compared to the massive old behemoth that is a permanent fixture in the basement.  

I have done a few.. and well I guess we are just spoiled on the west coast with our very organized and efficient foreclosure disposition rules and methods..
