Rehab costs and ARV (After Repair Value) are key parts of evaluating deals, so it’s great that you’re diving into these concepts early.For rehab costs, creating a rough estimate starts with understanding the scope of work and local pricing for materials and labor. 

Price out as much as you can in terms of materials and estimates.

And sometimes, we are not materially improving what you could have done  yourself. 

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.

What is he charging for the materials?

To address this I took detailed pictures from beginning to end of my most recent flip, documenting that we did a thorough job using quality materials.   

Some of the materials we choose and asked him to pick up (such as flooring) he replaced with low quality materials, I assume to keep more of our money for himself. 

I would also add, a contractor that you can buy materials for and they know how to put them in with little to know direction (reduces the management time of the project).

Sometimes I think, well maybe that newby is an expert at draining swamps....or they have a helicopter to reach the landlocked property and want to practice aerial concrete and building material transport.There was a guy on here the other day, challenging me that he could not possibly go look at all the "deals" he was going to buy in Florida for 10c on the $1.
