Has anyone had luck using auction houses to buy deals?

[Gabriel Ehrlich]

Hey BP!

I am a part-time Real Estate Investor out of Baltimore. I was just curious if any of you had  luck using auction houses such as Alex Cooper or Hudson and Marshall to find your deals. I've always wanted to attend an auction but they seem to be scheduled during the week at an obscure time where I wouldn't be able to easily leave the office. I would be more motivated to attend if there are other investors on here doing it successfully.

For those of you using auction companies, do you have any tips and tricks for a first time bidder?
