@Kevin Sobilo I do grately respect your response but trying to stick to my questions. 

A cost segregation study is a strategic tax planning tool that separates the assets that have a shorter useful life and can be depreciated over 5, 7 and 15 years from the residential rental property or nonresidential real property that are depreciated over 27.5 and 39 years, respectively.

What do the photos look like?

Are their listings detailed with good-quality photos?

As everyone else said, if you aren't getting traction, it's either priced too high or you have terrible photos and description.

After seeing a video somewhere, I made the tool in the photos, using wood, some screws and stick-on rubber safety tread from Harbor Freight: https://www.harborfreight.com/self-adhesive-rubber-safety-step-tread-98856.html.

@Jared W SmithWith all due respect to Architects; setting a standard percentage of cost based on construction cost is not good pricing for customers.

To manage this relationship, landlords should establish clear boundaries, respect space, use a third-party property manager, and set expectations for tenant responsibilities.

Photos before and after are always helpful also. 

They own those photos.
