I know there are a lot of hidden costs in buying a home to live in and even more when buying an investment property.  

It definately has to be that hidden gem of a deal around here.

You'll find yourself listening to podcasts, reading the BP forum, checking the MLS for new deals, contacting financial instructions for loans, etc.

Agents don't have a long list of hidden deals that they are holding on to.

For example, in Ohio it is not okay to use "realty," "realtor," and a variety of other professional designations if they do not apply to you- and I only know that because I read the instructions that came with the filing forms. 

I make my money from rent not some hidden fine print in a lease.

I was wondering if anyone could give me some insight on what hidden costs I might need to look out for what purchasing a foreclosed home at auction... i.e. is the buyer responsible for unpaid HOA fees, utilities, etc. and how can I determine if any such costs are associated with the property?

Any advice or constructive instruction would be greatly appreciated,

I looked around a bit on line, but most instructions were for circumstances where the house is vacant.
