How do you factor inspection costs of unbought homes?

[Carrie Giordano]

Hello,

How do you factor inspection costs on unbought homes. I've backed out of two deals this year when the inspections showed too many unknown issues. I pay for it out of my "real estate reserves" so do I count that $710 against my other property's profits. Just curious how more experienced investors handle this cost of doing business.  Also, would you say $355 an inspection is a fair going rate?
