I offered the full asking price and half of the closing cost and offered to pay for my own home warranty.

Also note that with tax sales, you can never really confirm the validity of the tax sale until a court expressly rules on it.

If you were to assume the mortgage then yes you would need bank approval but you should get a warranty deed instead of a quitclaim.

Is there value in purchasing a home warranty for a rental property?

I've seen you ask a ton of really simple questions hoping that someone will validate your ideas. 

Between the home warranty company, the vendor, and the order time for the parts, it was going to be well over a week for a permanent fix.

I'm spending on repeat repairs for the same property and not realizing it; for instance, if i replaced a water heater in 2019 for Bldg A and for 7x other units throughout the year. 1 year goes by and there is damage to the water heater I would like a software to track when was the last time I replaced the water heater (and if it has a warranty) instead of searching throughout my files for invoices on which properties' heater I replaced. 

I've had realtors pay for home warranties and other incentives to get me to buy. 

The CDC eviction moratorium is likely unlawful and certainly over reaching in my opinion but I'm wondering how many of you have actually received a valid affidavit preventing you from evicting them for non payment.

The only above ground system I ever had to replace was a couple of kitec whole house warranty recipes from their bad choice of materials.
