As someone else mentioned, tax savings are purely speculative based on many individual factors.

And that one didn't work anymore, even after changing batteries.

My early analysis says the numbers don't make sense (unless as a purely speculative investment). 

@Shannon Tidwell-Porth - This goes at DST change with the subject "Reminder: Cold Season Preventative Maintenance":Folks,As [Daylight Saving Time ends this Sunday], here is a checklist that every homeowner/renter should go through: 1.Replace smoke/carbon monoxide alarm batteries.The National Fire Protection Association suggests replacing your smoke and CO alarm batteries twice a year, which is why they also suggest the task coincide with the twice-annual time change.

Especially to do it right and get Leeds Certification. 2) A lot of the building techniques, products and practices are not practical, they are just there to be cool and groovy. 3) To run a house with solar requires a huge system, plus battery back-up, once again terribly expensive with a long payback that limits it to the wealthy.Not saying that there are not positives to the whole concept, of course there are, but it is just not viable, may never be, because unfortunately, money is the driver as always.

I had my realtor check it out and he told me someone turned off the Wi-Fi on the lock and took out the batteries.  

This is purely a financial decision based on the specific financial numbers attached to this property.  

I think most of the work would be purely for the purpose of being able to increase and maximize the rent per sq ft.

The idea that you can invest very little and make $100K a year is pure bull.

And yes one can (and I do) run numbers modeling that but we then run into the problem you so eloquently elucidate upon in your "I NEVER" post above: That the future is unknowable, the best we can realistically predict is a range of probabilities, and anything more than that is pure rationalization.Which brings me to an interesting question Denise: If we locked your future is unknowable view from your post above with the I can predict future incomes from your post before it in a room who would win?
