I would find a demo company to handle this as the city will be significantly more expensive.As for the tax lien, it would attach to the property, not you. 

So I have a crew (that includes myself) that go in and demo them.

Is he capable of rolling up the sleeves and working on this unit, ie painting, cleaning, demo, etc.  

I can't seem to find the repair estimate sheet I used, but I remember the total and what I factored in: electrical system replacement, new kitchen, new baths (2), carpet on two levels, demo/drywall basement walls and ceiling, replace HVAC components. 

The timing was impeccable, took pictures, called insurance, had them demo and fix the pipe.

And just to be more ambitious, this is the list of everything I want to do:- Clean all the junk and debris from the house and yard and demo the shed in back- Replace the roof and fix the gutters/soffits- Landscaping- Replace all the windows with double-pane vinyl windows- Replace all the floors in the house (ceramic tile for the kitchen/bath/laundry room, and vinyl plank for the living room and the upper level)- Re-do the bathroom with new everything -- plumbing, tub, shower surround, floor, sink/faucet, toilet, mirror, accessories- Re-do the kitchen with new cabinets, counter tops, and sink/faucet- Paint the entire interior (white ceilings, beige for walls, white for trim)- Replace all the light fixtures, outlets, and switches- Replace the front and back doors and put in new locks- Add smoke detectors and carbon monoxide detectors as required- Finish off the upper level (that was begun by someone else)I want my rehab budget to stay at or under $30,000 and I want to complete everything within 2 months from closing. 

I would only buy it for the price of the dirt, demo it and rebuild.  

So, for example, I wanted to register for a demo of some software, but I don't want to get the impending infux of spam from the vendor.
