Preforeclosure property question

[Carol Lam]

I found a preforeclosure property that I am interested in doing a complete make over as primary residence. The EMV listed on the foreclosure listing is 1.6M, Redfin has an estimate of 2.5M.  It's a small property, 1024 square ft.  How do I go about inquiring about the property.  Do I call the trustee directly?  Is it possible to negotiate price on EMV?  

Does anyone know of a reputable contractor who can help with tear down and complete renovation?  

Thank you.
