Cost segregation study- when and why should i fo this ???

[Sachin Maskey]

Hi,

I am looking for feedback and benefits of doing cost segregation studies for 3 unit multifamily . I recently purchase this multifamily on 5/2020 . i was wondering if this is worth doing and when should i do this . I got the estimate around $3000 for the cost benefit analysis and this is without travel/accomodation cost . 
Your expertise will be highly appreciated 

Thank you
