Got my hands on a deal, little help

[Igor L.]

Was fishing around and caught a whale of a SFH.

Off market brewerytown deal between 28th and 29th on W Master st.

This thing is a monster at 26000 Sq ft, fully gutted and framed already with 7 ft high ceilings in basement. 

Asking price is $180,000.

Needs full rehab.

Comps on zillow go only so far. 

New construction go for 400-440K.

What do people the the ARV on something like this would be?
