Foreclosure Newbie question

[Roberto Chan]

I just join BP.  It is great source of info.  I been reading about foreclosure and doing some research on them. 

I see lots of people advice against them.  But this is what I have been gathering

what I don't understand is the fear on it.  I know there are unknowns.  but once you purchase win the action on the Senior Lien.  "Most liens will go away"  

The liens that can affect you will be State Tax Lien, IRS Lien and Superior lien usually from an HOA.

But if you see the court files and see all the judgement and make numbers and add it to you "possible liability" and some rehab worst case scenario and you can still come ahead why not do it ?

I know there are a few liens that could come like a contractor fixed the root or something like that.

Am I missing something ?  

Again, I am not saying I will do it.  I am educating my self so if in the future I find the courage to get into that I have all the info.

Any advice is greatly appreciated.  

Thank you all.
