Still a little rusty on analyzing properties but just need to practice more. 

Tenting and fumigation is common practice here so they dont scare me away.

Is this common practice?

This could be interpreted as practicing law which all agents need to avoidHowever, in my opinion it does not effect the lease at all as once the lease expires a 30 day notice by either party would terminate the lease@Jerel Ehlert While I understand that the 30 day notice is necessary after a foreclosure, I believe that does not apply to the owner if they are still in the property. 

I know it would vary state by state as far as pricing, but I thought standard practice would still be generally the same in regards to it being a flat fee, hourly fee, or % fee.

This house is 3 level tiered house and the garage is the lowest level so it is practically a basement/garage. 

Is this a common practice?

If not practical, or if you prefer remote investing, then I'm not sure what a good recommendation would be.

If you have an upset tenant then you have two problems to deal with where as if you practice preventive maintenance you only have your serviceman to deal with. 

While his business model wasn't completely interesting to me in a practical sense, I agreed with some of his concepts.
