I think I should be able to get a close to accurate estimate as the demo has already been completed.  

Personally, I wouldn't have any issue buying a previous marijuana grow house, especially if I was going to demo it and start from scratch.  

overall strategy looking for value add upside in occupancy rates, a property that cash flows close to breakeven or breakeven+ vs the debt service, on a corner with strong demos with decent traffic counts and a "draw" anchor ie grocery. 

All in, after demo, site prep, change orders, I expect they'll be closer to $225/sq ft.

I mentioned to a fellow investor and he told me to add minimum $3K to my demo budget just to remove all the left over furniture and "JUNK" from the property before I could even start a true demo and rehab of the property.

We started letting them come by the job site on day one of any flips for a few hours for light demo (before we turn it over to the professionals).

However, whatever happens everybody else gets their pay, e.g. the carpenter, the electrician, the laywers, the title agents, the insurance company, the demo guys, the flooring company, landscaper, etc. 

@Moly Yang I don't think it's worth that.

Hello all,I am closing on a duplex house hack shortly.I was going to put in new kitchens in to modernize the look of the place.But renovation costs have now become a bigger factor/concern than originally anticipated.I am trying to achieve the same result without the demo, disposal of old cabinets, plastering, tiling, painting and coordination associated with all of the above.The house is 8 years old and the kitchen cabinets are original and in fairly good condition (just a little dull looking).I would like a more modern look than the varnished wood finish of the cabinets currently in place.

The work needed is full electrical replacement, full plumbing replacement, 20K in foundation repair, lead paint removal, exterior siding and carpentry repair, roof repair, both bathrooms replaced, sheetrock work, second floor needs more bracing, asbestos siding was disturbed, workshop 25'x50' needs to be demoed, hvac install, stair repair, all carpet upstairs removed due to human and animal waste, and back porch repair.
