Post Auction - Lowering Your Tax Bill

[Chris M.]

In Allegheny County, when a home sale occurs, it seems like the county automatically reassesses the home for the new purchase price.  

What happens when a home is sold at a fraction of the assessed value?  Does the county reassess at the actual purchase price?

Example:  Home is assessed at $100,000 today.  The home sells for $25,000 at a tax auction.

Question 1:  Does the assessed value automatically get changed to $25,000?

Question 2:  If it does not automatically get changed, is it likely that you can win an appeal for $25,000 since you paid the highest value offered at a public auction?

My goal is to buy a property at an Auction and BRRRR and a big part of the cashflow analysis depends on what the property will be assessed at.
