Non UL electrical, plumbing &HVAC materials.

Learning how to use the correct tools and materials for a job, YouTube videos and even ChatGPT will help you get through 80% of the problems you will run into.My rule was I would not mess with HVAC, plumbing and electrical Or if it would take more than a few hours. 

While the cost can vary depending on the scope, zoning, and materials, I’ve seen similar projects run anywhere from $50,000 to $150,000, depending on factors like plumbing, electrical upgrades, and structural work.If you’d like, I can connect you with a few contractors or architects in Chicago who specialize in basement conversions.

The roof, AC, plumbing, electrical and flooring will eventually need replacements.

Electric heaters are dangerous and can start a fire if left unattended.

@Jorge Caceres Is this with electric baseboard heaters or  heat pump/minisplits.

Roof, plumbing, electrical upgrades? 

If there’s specific projects like electrical we get a project specific estimate after we put it under contract prior to the earnest money going hard.

It was a huge investment, but it cut the electricity cost by the full 2K per/mo all summer.

Quote from @Aaron Wolman: I would call the companies (gas/water/electric) to get estimates, or an estimator out there.
