I don't do business with realtors or insurance agents due to the comedy, the main part of which has already been mentioned: problems getting paid. I gave one of them a chance this year and sure enough, never got paid... Needless to say, as soon as a cut goes unpaid, no more service.
Then IF the owner is responsible vs. the realtor but the realtor hires me to cut the grass, GOOD luck getting paid again, the owner knows nothing about any of it and the realtor doesn't care because the house isn't theirs, either. I say if the realtor wants the grass cut, let them get out there with their own machines.
