I have an option to live cheaply in my in-laws new home for a few years before they move down after retirement. I was thinking about renting out my house while doing so. The only problem is I would only be able to charge what I owe on my monthly mortgage. I would not be able to get much extra. How does renting change how I pay taxes? Would the $400 a month I save by staying at my in-laws be worth it after changing my house to a rental property? Thanks,
