Even if the data comes out clean, you can still learn so much about them. 

After years of cleaning, dealing with tourists, and having to be on call 24/7 you could not pay me to do STRs.

I doubt your tenant has one.Also, in HUD ESA guidelines the Tenant must abide to any pet restriction or rule not affecting the ESA animal’s ability to provide support - like county license, vaccinations, leash, waste clean-up rules, or spay/neuter regulation. 

Insurance probably sent an inspector who gave a ballpark repair cost in addition to the cost estimate the clean up company provided.I'm assuming you used the clean up mitigation company the insurance suggested, who may not be your best choice.Get another estimate to return the property to full glory, cost for paint, glue, dumpsters, every nitty gritty drywall screw, plus putting your tenant in like kind housing.

I moved on to purchase rentals that are clean BRRRRs and built a rental portfolio of over 7 figures.

I'm trying to find something more durable than carpet (seems to only last a few years) and am turned off by pricing on vinyl plank.

Most landlords avoid carpet in rentals anymore.

I think a ReafCo filter would clean up half of the issues.

I have 3 bedroom 2 bath residential home in a nice area on a nice block which all the neighbors have well kept up and clean homes.

Now that I’m paying 18% (which includes cleaning fee) then paying out the entirety of the cleaning fee as well feels like double dipping.
