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.

I hate full blown Landlord Software because I only have about 10 units and hate the fees...I am a big fan of the "Lite" Landlord Software and the only one for rent payment that can be 100% free for the landlord and the tenant WITH automatic late fees is apartments.comI actually did a whole video about this on my YouTube channel comparing the must have features of any rental collection tool!

Perhaps there was a more official way to deal with it, but this worked fine :)

@Vito DiIennaWhile I have not had to get a Letter of No Objection myself, if I had to do it, I would go right the the DOB, go into the Office that you can get an official Cert of Occupancy and ask them what is the procedure to get the letter.Normally, you will need to provide evidence.
