What are some tools you've been using to manage your properties?

[Alex Zhao]

I have been having trouble managing my properties because of the long list of never-ending things. Bills, repairs, late payments, etc... It is getting to be a lot. I have just found this forum from Google a few days ago and I was wondering what tools you are all using to keep everything organized. 

I have heard some people use spreadsheets, but I am unfamiliar with it. Does anyone have any recommendations?

Thanks,

Alex
