You're generally limited to doing one room at a time, which is not very efficient.  

Is the home energy efficient?

If it were gas power, I would be more concerned about proper venting/carbon monoxide etc.  

You can try to offer to buy the tenant out of the lease(Cash for keys) understanding that the power lies withy our tenant as they have no obligation to accept Evictions occur wihen a lease has been violated.

EVerytime I run models, I see more power in acquiring properties every year vs sitting in one place.

As investors, we are always looking at how we can modify, tweak or change what we are currently doing to become more efficient and profitable.  

Knowledge is power, so I see nothing wrong with learning to become an inspector, but a good inspector becomes good by inspecting houses, not by reading books. 

Yes, you get the lawns mowed and access to pools, but you also always seem to get people on the HOA board who get a little power and go nuts. 

Original single pane windows with hardwood frames and custom wooden storms outfitted with spring bronze are equally as efficient as double pane vinyl inserts and completely worth saving because they will last 200 years instead of 20.

You need education on creative financing, power prospecting, contract engineering.
