Balloon payments need to be after significant equity has been established, that 25% may apply, the improvements will effect this as well, but future ability to finance is the question to ask.I realize some of this may not be appropriate for public consumption, feel free to contact me with confidential matters and I'll be happy to give you financing solutions and options. :)   

The maximum amount that can be claimed is $1.80 per square foot if there’s a 50% reduction in total annual power and energy costs.There’s a partial deduction of $0.60 per square foot for reduction of energy consumption by HVAC, lighting and the building envelope.There’s a partial deduction of $0.30 - $0.60 per square foot for reduction of lighting power density of 25-40%.If I claim the Section 179D deduction, will this trigger an audit?

The actual water consumption would be the same whether all of the flush goes in the sewer, or some of it in the basement...

I could continue, but I think you can see that Las Vegas is a desirable place to live, especially when compared to California.RisksWater - Today, between 70% and 80% of all water consumption is wasted on grass.

To demonstrate my technical competence, for my personal house I built a steam shower, installed radiant barriers with rock wool, and a wood stove insert with bathroom radiant heated floors and re-designed radiant floor heat zones, cutting winter energy consumption to 1/8, installed a whole house fan cutting summer energy to 1/2, extensive localized landscaping leading to a reduction to 1/8 the yard work, plus random quality of life improvements like wifi switches, heated floors and toilet seats, skylight install, exposed structural beams, and master bedroom laundry including electrical and plumbing, cathedral ceilings with skylights, a steam shower with wifi controllable lighting and music, concrete countertops, etc. 

I trust their research.In summary, in the short term, there may need to be a change in Las Vegas residential landscaping to reduce water consumption (lawns, etc.).

But from a residents POV we all still have to live so we continue as usual just taking precautions and measures to ensure our families are following safety procedures using filters and bottled water for consumption as much as possible. 

I will tell you more when we meet, but it isn't for public consumption at this point.

The most common source of higher water consumption (at least what I found) is a toilet running constantly... and it is a $10 fix.

There are some grant programs to reduce energy consumption that may make sense to perform certain improvements sooner.
