Any experienced auction buyers?

[Ana Barros]

Hello all,  I am looking into flipping in Houston area. I am very interested in finding foreclosure deals through online auctions, but since this is my first time, I have a few questions to the experienced ones. Before bidding, do I need to pay an inspector to check the property? Or is the inspection provided in their listing reliable? When interior access is not available, is it still worth considering it? Is an agent recommended when buying through auction?

Thank you all in advance, looking forward to reading your replies!
