I’m considering buying a duplex and renting out one half while my girlfriend and I attend college.

I forget the number right now but if you are within I think 5 days from sale date the lender isn't obligated to reinstate, but still may.You may be able to delay the foreclosure by simply asking for more time, you are now the property owner and have some sway.A couple observations:You don't have title insurance as no title company will insure a trustee's deed in CA, so that won't help you.You won the auction based on your commitment to occupy the property (SB1079), so this is not a quick flip.To buy time and delay foreclosure you can file a stripped down bankruptcy.You can't stop payment on the 86k wining bid since you paid cash at the trustee sale.Generally trustee sale buyers don't have a real good feeling for the property condition, unless you do for some reason, so this is a wild card. 

I did not buy the property also if you know any buyers, fix & flippers can you give me their contact and or give them mines please.

Is it buying a new home for you and your fiance? 

Investment Info:Single-family residence buy & hold investment.

Don't buy just because of the numbers.

Did you have a good agent on the buy side? 

I do have answers to those questions and a specific buy box. 

If you are experienced you can represent yourself on buying and selling. 

Better to buy now before rates go down, price go up even more and crazy bidding wars return.
