Just finished a demo from Cozy - it looks pretty straight forward. 

Those who tow large objects know the benefit of self leveling air suspension over steel springs.My ride now that I am doing demo and doing renovations myself is the same Cayenne. 

Recently we have been so busy that I actually started getting day labor to come help with demo.  

Question: Is there any demo involved?

So, now I've gone from a cashflowing property to a property that's costing me a mortgage payment every month and needs over $50k of work (the only way to fix the problem was to demo all of the flood damaged drywall, cabinetry, and  trim, jackhammer through the slab, excavate and remove over 5 truckloads of concrete and clay (by hand), install and plumb an industrial level sump and irrigation system, backfill it with rock (by hand), re-pour the slab, and re-finish everything.How is this relevant to your question?

I like to do the demo, paint, and some of the smaller finish carpentry stuff.

I am currently in the process of demoing the interiors and installing metal roofing over the existing structure.

Hire two demo guys for $12/hour to remove it.

Here are a few things that I have learned over the years that might supplement the spreadsheet discussion:- you never understand the full extend of the rehab until the demo is complete!

If you want to do demo and clean up you might consider getting a contractors license to do demo and clean up although you probably would not need a license to do just clean ups.
