Just had the carpets cleaned. 

Start with the low hanging fruit, using chat gpt to write some social media or blog posts or clean up a newsletter to make it more professional.

Friend of mine today said his housekeeper called and said her car got repossessed and had all of the cleaning supplies in it. 

I'm an investor in Columbus OH myself and have purchased rentals that are clean BRRRRs and hit the 1% rule.

My HVAC people said they are troublesome to service and keep clean as they don't have the simple filters to change like conventional systems do.

We leave it on full time and have our cleaning people drain it after each stay.

If you do, I'd suggest getting a housecleaner in once every 1 to 2 weeks to clean common areas and bathrooms. 

One thing I discovered recently is they make heavy use of the Schedule E from your tax return, so if you clean up your Schedule E (eg by minimizing repairs and maximizing CapEx and accelerated depreciation), you should be in much better shape.  

As a local investor here in Columbus myself, I have purchased rentals that are clean BRRRRs and grew my rental portfolio to over 7 figures.

It shouldn't take more than five minutes.There's not much you can do to accelerate the process with cleaning and repairs.
