A good electrician is going to cost a chunk of change to replace all of the wiring for the house, and a good Plummer will be pricey to replace the old pipes.  

They do everything from framing, trim, painting, roofing, siding, flooring, cabinets, etc. and they can tell you when the plumber or electrician didn't show or did something wrong.

This gives me access to a large network of skilled contractors, including plumbers, HVAC specialists, electricians, and general contractors.I’ve identified a promising opportunity with an auction property, but I’m unsure how to accurately estimate rehab costs with only a small window to do so.

He is an electrician and lost money that had a big impact on his life, set his family back a few years financially, prevented them from being able to buy the house they wanted to for themselves to live in, caused a lot of stress in their relationship etc.

If you aren't a licensed contractor, plumber, or electrician, you should not be touching those things, much less doing repairs or upgrades on those items.

I generally chat with the electricians, plumbers, and flooring installers when they come to work on one of my properties and mention that I am looking for a house to buy.

Break down your rehab into individual jobs, for example get a electrician for electrical work, a plumber to repipe the house, a dry wall guy to close out the walls, etc.

:here's a quickie - always have the plumber before the electrician.

Just hire an electrician, hire a plumber, and you can do all the rest.

Buy in super small towns and they may not have a plumber, electrician or HVAC person who even wants to visit your project?
