Generally, materials are broken down into two categories:Rough Materials (lumber, nails, screws, brackets, piping, fittings, mortar, wiring, outlets, switches, drywall, etc.)Finish Materials (tile, grout, flooring, paint, light fixtures, plumbing fixtures, door knobs, etc.)The way that I structure my contracts is that I buy the finish materials and have my Contractor provide all rough materials.I think it's strange your Contractor wants you to buy piping, brackets, etc, because I would classify that as rough materials.There's no way I would ever want to be responsible for buying all of the piping, fittings, elbows, p-traps, etc for my Contractor...I would be at Home Depot all day buying and returning stuff! 

Were there any unexpected costs during rehab?

They build in extra padding, so the unexpected does not derail the entire project.When creating your budget, make a room-by-room outline of work needed and estimated costs.

I've only posted a few times as I've been trying to "simulate" deals as I find them - but haven't jumped on anything yet.I originally considered condos but they are out of the question now due to HOA irregularities and unexpected circumstances.

It looks good on paper, but a single unexpected expense will ruin you.

It is an acquisition from existing owner. all retail outlets are leased out for next 4-5 years. 

This sump pump is not running and if I do let it run it causes smoke from within hence the plumber adviced to remove it from the outlet. 

Change all outlet and light switch covers. 9.

If you are planning on not having other partner PMs, at least have a network of other PMs that can take over during unexpected emergencies or vacations.
