If you are looking for a rough idea- Biggerpockets has a tool called the rehab estimator.Link:     Biggerpockets rehab estimator-or-Just go to the top of the screen, hit tools and demo the calculator. 

Purchase price: $82,000 Cash invested: $2,000 Sale price: $95,000 Purchased a house did some demo then sold it to another investor How did you find this deal and how did you negotiate it?

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. 

Even if it's just to try it sometimes they have Costco roadshows that demo the product.What are you working on these days?

I had some friends help demo a property and I paid them cash (around $1,000 total).

They have since left the house and now he doesn't use the lot, so there was only a small tool shed on the lot to demo which didn't cost very much.

The only downside to that rig is when you need to haul dirt, or demoed concrete, which is thankfully rare.If you get big enough, I think a high-ceiling van like a ProMaster 3500 is the way to go, at least, that's my dream vehicle for this.

I'm guessing demo will be done by Wednesday at this rate.
