This training can make you a multi millionaire  at best or put 50 to 100k+ in your pocket every year part time. 

In my area (near the beach) its mostly families and they want cabanas, baby items, chairs, coolers etc that we do not provide but I have a local vendor that delivers and picks up these items and charges a few dollars per day for each item, and give me a 20% referral. 

Here's a https://www.irs.gov/businesses/cost-segregation-audit-technique-guide-chapter-4-principal-elements-of-a-quality-cost-segregation-study-and-report to the IRS website noting specific items that are included in the cost segregation study report. hmm, that website is a 404 error.  

A lot of training actually.

If its a volunteer fire company you may be able to donate the house to them for the purpose of training and get a tax deduction .

Quote from @Tangie Pate: Has anyone purchased the Lee Arnold System and used his pre-trained virtual assistants? 

Occasionally I catch some cleanliness issued that I am not satisfied with which I believe is due to variability in attention to detail between people on their crew, or lack of training and familiarity with my property.I've seen mentions of the value of post cleaning pictures from hosts on other forums.

If there are items of value left behind, or even personal items of sentimental value, I will follow the abandonment rules to a "T" to avoid any legal issues.

Scott, thought this might be interesting for your company and for use in your training and such.. 

$540 is not unreasonable for a home of that size and the items you mention.
