A new electrical panel may not need any demo work.I think the other solution is to demo back your work. 

Just a heads up, these numbers are purely for demo purposes and may not accurately reflect current market conditions.I do recommend shopping around with three different lenders.

The cash invested figure was for plans, permits, demo, construction, and staging.

Demo and roof needs permits. 

One week prior to the tree falling, the neighbor demoed the house and 2 days prior to the tree falling, scraped the lot leaving it bare.  

I want to hold long term, so will definitely look into the market's demo trends and economy.

We demoed out the old flooring throughout the whole house, countertops in all bathrooms and kitchen, removed the old appliances, and did a lot of landscaping cleanup including the removal of a few dead palm trees out front and tossing the old fence.

First thing I had to do is demolish the mobile home, so I filed for a demo permit and demoed the home myself.

@Sheng Yang What regions are you focusing on?

You typically need a permit for demo.
