When you're landlady decides to sell her house ...

I have never experienced this open-view house thing with our previous landlord so I don't have any idea how frustrating and irritating this thing might be. Apparently, our landlady had decided to sell her house and her agent is really getting into my nerves already. I don't know if its just me, or there are others out there who doesn't want strangers checking their house every now then! It's in the contract though, but my goodness, we are still staying until the end of next month and we'll be bearing with these people and the annoying house agent! Can't this landlady wait at least until next month to do this whole process? Ahhhh ....
