2008 co-op apt. converted to 2024 Rental

TO Carl - if possible,

Thank you for your many excellent responses re conversion of owner to landlord. I'd appreciate any help you can offer re my 2024 conversion of coop apt. to rental apt.

Determining basis - Purchased coop in 2008. Do I need 2008 closing docs?

How do I determine land %?

I actually have 2008 vague appraisal & some 2008 paperwork.
Do I need to compute coop basis/coop expenses added from 2008? If so, how?

I'm not sure how coop's o/s underlying mortgage values, at different dates, come into play.
Or just use Market Value?

My unit's specific mortgage is paid off.

Do I want to claim Safe Harbor status.??? Most of my own immediate expenses are less than $2500 each. Not sure I really understand Safe Harbor.

05/2023 Started trying to rent my co-op, on my own. (no major expenses in 2023- just local fees, last minute fixes.)
11/2023 Listed with a realtor (tenant paid fees) .

12/23 I started living elsewhere, leaving only enough items for "staging" and occasionally stopping by to insure apartment was in good order for showings.

05/01/2024 Renter moved in .

Willing to start this whole process, for tax purposes, from 01/24 through 12/24.

National Management firm has FT office on property and issues monthly statements, with multiple line items:

Assoc. Fees, Mortgage (underlying), R/E Taxes, Reserves, optional amenities like parking.
Please see attached 12/24 monthly "Shareholder" statement.

Where do I enter each line item's 12 month total?
How do I classify these line item's annual amount on 2024 & future years' Schedule E ?

Coop's accounting firm sends y/e 1098 showing per share/total, underlying mtge interest amount and real estate amounts. I don't understand the additional explanations in the form's in the cover letter. I did not save all of past years' cover letters plus these letters' information has varied, based on different accountants/regulations over the years.

How would I apply these comments to Schedule E 2024 and future years?

I feel I am close to understanding....but worried how year 1 decisions truly impact the point of sale (hopefully not for a while.) Thank you in advance for whatever details you can provide.
