Unit Inspection question

[William Goolsby]

Ok guys (and gals), I need some help.  I'm purchasing (2) 16-unit, identical properties in Oklahoma, and I'm trying to schedule inspections.  One was built in 2008 and the other in 2011.  I know that every unit needs to be inspected by someone, whether it's me, my partners, a contractor, etc.?  Is it common practice among investors or investment groups, however, to pay a licensed inspector to check each and every unit, or just a few in each building?  Thanks.
