If the heirs really want nothing to do with it, and there aren't junior liens, you may be better off paying the estate a nominal fee for their interest in the property, and negotiating a payoff with the note seller.

I too started thinking about it my junior year of college. 

It may wipe out lien that are junior to that property, but not to him personally if they are judgements against him or have his personal guarantee.

The sale will only extinguish matters which are junior to the creditor asking the Sheriff to sell the property matter that have been properly served. 

Here in California, they just added to the ADU law, and now allow a second "junior ADU." 

For example in my investments in SF - I identify properties that I can do layout changes on - I’ve taken a studio (with a detached kitchen) and converted it to a junior 1br (with open kitchen) That bumps my rent by much more than just doing traditional rehab.

How to fined out if the foreclosure is by the primary or junior mortgage lender? 

I am currently going into my junior year of college and still have no idea how I want to use my major for my future job.

I am a junior in college studying Entrepreneurship and I don't want to wait until I graduate to decide what I want as a career, I understand that real estate is the best return on investment.

@Cherie Orellana I'm currently a junior in college so don't plan on buying until 12-18 months from now.
