Should I do cost segregation or not on 2 str?

[Richard Unsworth]

Hi all, would appreciate some thoughts on whether to do cost segregation studies on both STR properties I have acquired in the past two years or just one? Some details

- RE pro tax status

- cost seg study of one house would yield $100k deduction or both $200k

- as re pro active income can be deducted but only have $60k active income so total tax paid $15k?

Cost seg one property would help for this year but worth doing both for 200k accelerated depreciation? Or should I keep one str on its current regular depreciation schedule and cost seg just the 2022 purchase. Benefit to accelerate both through cost seg this year? 
Pros and cons would be appreciated!
