Don't be touched by her actions. She's just doing her job. It's like you going over to a restaurant and ordering a plate of noodles and then you are served. Remember that she's getting paid.

For tenancy secured by real estate agents, 1 month rental being their commission is the current market practice.

To be honest, though she has been helpful all these while, I just wouldn't trust anyone with cash money, especially when it's my money. Plus, you NEED to go over to your property once a while to make sure your property is not thrashed.

Don't be lazy unless you are demographically challenged OR your purpose is to see her once every month =D
