best way to further education on home design for my flips

[Mikki McIntyre]

I am currently working on my 6th fix and flip property. I want to further my education on home design. Obviously I have full time contractors that are doing the work on the rehabs but I need to learn more about redesigning kitchen layouts, lighting, flow, etc. Most "interior design" courses I come across are more focused on decorating rather then actual design. I would also like to learn more about the mechanical processes of homes. not looking to become an expert but at least understand a little more about how it all fits together. I live in the NJ and Philly area so any advice is appreciated. thanks
