Demo costs (assuming its not a slab house) is pretty cheap, but something to consider if buying a teardown for land value only.

Hey @Miles Yang, super excited to chat with you on this subject.

I will be the project manager overseeing this amazing flip.Details:-1600qft/3BR/1BT-Two car Garage-Shared driveway-Built in 1907-Foundation damageGoal:-Fix foundation and falling porch-Make an open concept layout -Add bathroom to master on the second floor-New electrical-New Plumbing-Add A/C and upgrade furnaceI started the project by doing the demo myself and contracted out the rest of the needed skills.

Im still early on in my planning stage, so I don’t need a demo yet.

The good thing is all demo is done and framing is also completed.

I'll be starting close to home for multiple reasons: I have to continue working my actual job for a while to continue paying my bills, I'll have to be pretty hands-on to cut expenses where I can (i.e. do demo myself, I can paint by myself, I could probably even do minor sheetrock repair which would leave cash for things like electricians or plumbers because those are things I know nothing about), and I'll want to learn general things from skilled trades people (how to spot potential issues, etc) so that I can make more informed decisions

However, you do have the demo/bringing unit up to code issues. 

.  :-) We figured we could save by doing some things yourself like painting, some demo, and acting as the GC on some of the projects like HVAC, Roof, windows and siding, then using a GC to coordinate everything on the inside. 

With regards to the fire, the only thing I would do different is go in and demo absolutely everything.

My additional costs that I can sub out would include to complete the project; site work, demo existing foundation, new foundation installation, septic install, remaining 15% exterior on the roof/siding, landscaping, front porch installation, interior flooring, kitchen appliances, final coat of paint (delivered with primer), stair sets to basement, furnace & boilers along with installation, water tank & pump with installation, electrical (panel box set up, utility meters, electrical connections), plumbing connections.
