How to do due diligence on auctioned properties ?

[Nazgul Tataeva]

Hello everyone,

Two years ago me and my husband bought a duplex to house hacked. We lived there 1,5 years and purchased new house to raised our growing family. Now, I would like to start learn more and start somewhere to BRRR. I looked few properties but there are listed on Zillow as foreclosure sale. I know it's risky move to buying without seeing inside the house. I want to start from somewhere and learn along the way.

Could you share your experience?

Thank you in advance!
