However there are other ways to optimize depreciation across multiple properties and multiple years.

The question then becomes "What is the optimal investment strategy to minimize tax liability and maximize appreciation?".

The first is optimization - that's what everyone in this thread is already on about - taxes, refinancing, reinvesting.  

So I'm looking for a contract that optimizes on clarity and comfort for my seller (or buyer), even if it requires some 2017 technology to reproduce for each deal.

    Most Palm Springs properties that are optimized vacation rentals are rented 72 or so times per year.  

@Derek Kirkwood yes I am still currently shopping around for a CPA who is good with tax optimization for investing, but we turned in the reports from xero to our accountant for 2017 tax season and it was no problem for our current CPA.

To be optimally effective, modularization needs to be looked at upfront, preferably during the pre-conceptual or early conceptual design phase.

Besides that most people just don't have the discipline to stick with it, there is no way someone would want to spend the TIME to make the multiple calculations necessary to leverage EVERY penny in the most optimal way.Mark my words though... pretty soon this program is going to be as mainstream as "Windows" or "OS X."

For example, "fish tanks" is a head term, but "compare prices whisper aquarium filters" is a long-tail keyword.Beginner search marketers often focus on head terms when optimizing their sites for organic search or creating pay-per-click campaigns.

Are you trying to optimize your income from the laundry, or is it just there as an amenity?
