Arranging Property Inspection

[Lue C.]

All seasoned landlords out there,

I have a situation with one of my rental properties, and hope you can share your thoughts how to handle it.

I have been reading @Brandon Turner's managing rental properties book, and realize that I don't have a "regular property inspection" clause in my lease.  The tenant has been in the property for a year and a half, and I haven't been inside of the property.  I start to wonder the condition of the house now.  Because I don't have the "inspection every 6 months" clause in the current lease, how do I go about arranging one with the tenants, without them suspecting me checking on them?  I will send a my handyman to do it.
