Question about property taxes for distressed properties.

[Ben Bakhshi]

I am trying to estimate property taxes on a potential buy that was an REO in 2009 (sold for $50,000 at auction).

8 bedroom duplex asking $85,000 in Atlanta Georgia.

Redfin shows:
Tax (City & County): $2,250
Tax Year: 2011

The previous sale price was $370,000.

Any evidence that the property taxes will stay the same or be lower if we close on the $85,000 purchase price?
