Can you monitor only paying customers are garage parking if you start charging?  

Elizabeth,Great question, definitely going to monitor as my rentals are outside of Fort Stewart, Georgia and this will help me in the future.

Looks promising.It's called GPS Tracks.

I would point out that Kris was vigilant in monitoring his property and caught this situation and was not hurt.  

Had to monitor this thread so i can come back and read every post.

Traveling to and from a job site to monitor progress is not a good use of my time.

However, there are some places in the country where a renter could expect to pay more than twice that amount and the average monthly rent stands at $2,757, or more than $33,000 per year.Why rental prices matterHome prices often get the most attention in the national media, yet only 65.4% of Americans own their homes, and that percentage has declined in each of the past eight years:Meanwhile, the percentage of vacant rental properties has also fallen dramatically after peaking in 2009 at 10.6%, and now stands at 8.7%:It will be curious to monitor how these two data points trend in coming years, and whether this will represent a fundamental change in where Americans live.

I don't see why would it be the land lord obligation to report this because you can't control who an renter let's stay or sleep over at the residence.You can't be there monitoring who comes in or out.It has to be more too this story.

(HINT HINT I'm not going to be sitting there monitoring who is swinging what hammer.)http://assets.mymortgageinsider.com/wp-content/uploads/2013/04/Self-Help-Agreement-PDF.pdf
