Like you, i'd be interested if anyone here has any experience with doing this 'technique'. 

I'm not relaxed right now.

@Kim A. would say that a great thing any flipper can do is develop their own off-market seller marketing techniques.

This is even true for student debt.I recommend the old-school, proven technique of paying off all debt.

I used them with a lot of success throughout the years, but they were never a mainstay of my acquisition techniques.  

And the rules surrounding replacement are much more relaxed.  

And the rules are quite relaxed. 

The 1% rule incredibly flawed, even as a short form underwriting technique.

While the IRS does not mandate a physical site visit, the IRS cost segregation audit technique guide (ATG) does suggest conducting “field inspections.”It’s important to note that the ATG is not an official IRS document.It serves as a guide and cannot be used, cited, or relied upon as an authoritative source.However, the recommendations in the ATG are worth considering.According to the guide: “A field inspection is recommended to document the physical details of the building, type of construction, materials used for construction, the assets contained in the building, the size and types of building systems, and any land improvements that were included in the purchase of the property and the condition of that property at the time of purchase.”So while the IRS does not require a site visit for cost segregation studies, following the guidance from the cost segregation audit technique guide can be beneficial.

So many folks have relaxed a bit.
