There is such a wealth of books and resources for learning how to landlord and purchase SFH and even apartments, but I have been having a much harder time finding resources to build my knowledge level on commercial. I am thinking about strip malls, office, retail, etc. Things I am thinking about are turnover costs, operating expenses (typical), how appreciation works in them as opposed to residential.
If you have any books that have been helpful, or other resources, post them up.
Thanks,
DB
