Hence, no tax filing was done for rental income from this property yet.

Hey Joe, Having a large number of rental properties and installment sales can certainly make your tax return voluminous, but as long as you're maintaining accurate records, filing everything correctly, and reporting all income, the size of your return itself is not necessarily an audit trigger.

I don't want to use the classes/locations as it's not exactly good for tax filing on multiple LLCs. 

On ETSY you can also buy hundreds of digital files of abstract art in different color pallets for super cheap ($10-20), then have those printed onto whatever type of print and size you like with Shutterfly or any other digital printing service. 

It was for 2022 purchase filed in 2023 taxes (although we're going to have to file an amendment anyway, so maybe it's not too late??)

(I recently bought a quad and found out that two tenants did not have security deposits on file) Good Luck!

But now that the sellers want to file an insurance claim, I’m assuming the claim will take a good amount of time to be processed.

It contains hundreds of files such as ebooks, checklists and spreadsheets for real estate investors: https://www.biggerpockets.com/filesGood luck.

Like they want to file a Quiet deedRE is becoming over run with  OOS  BRRR ROI  COC etc etc.This type of thing is very common though in Aviation there is an abbreviation for nearly everything you do in Aviation. 

Next, you will need a real estate attorney in your state file a quit claim deed to change the title to the llc.
