Hard money to buy and flip tax sales?

[Allen Mewbourn]

First time newbie, but i'm looking into the Cobb County Tax Commissioner website (cobb county Georgia https://cobbtax.org/taxsalelist ) for tax property auctions. Most are only around 4k (even though zillow has the properties for around 180k), could I perhaps use a hard money lender to buy and rehab the property, then put it on the market for a great price? Does this sound possible? good idea?
