You can spend more time reviewing the details in IRS Pub 946, How To Depreciate Property....This post does not create a CPA-client relationship.

Hiring a Financial Advisor along with a CPA who are both real estate investors is another suggestion I have for you.

These are good questions for a CPA, not random internet people.

That is my guess, but I am not a tax professional so do consult your CPA as this is just my opinion/guess.

As an accident to start a short-term rental for more than 3 years and wanted to end it. 1) The number from CPA for this short-term is worse than any other long-term rentals. 2) the time spend for this short-term is  >=5  long-term rentals. 3) from Sep-2024, there are 6 books to the end of the year. 4) Insurance of short-term increased 27% and tax will increased without doubt.So tried to cancel all the reservation from AirBNB two month away.

What I was told if that I shouldn't pay down my mortgages if I can get a better ROI somewhere (I'm not a CPA or financial advisor, just sharing what I'm doing). 

This would still give them a monthly cashflow, cure the capital gains tax requirement when sold [ check with CPA or tax attorney] and alleviate the maintenance / management issues that your parents currently have.

Can you recommend someone for cost segregation and a CPA in the Dallas area?
