How do the mentor groups work? 

Ok, I wasn't spamming (I don't even sell anything I could spam) but I was pasting a "hi" message to new members THE SITE RECOMMENDED TO ME.

I currently reside in Ohio where I buy SFR rentals and do a couple flips a year.

To set the scene: A cost seg study breaks your property into two important categories:1250 "real" property aka the building, foundation and other long life assets.1245 property aka anything that can be accelerated such as 5, 7, or 15 year property like carpets, cabinets, or other site improvements.
