You'll want to put together a personal financial statement (basically lists of all your assets and liabilities) and have your tax returns ready.

Have the tenants take and send pictures of any maintenance items and video chat with the repair person as needed.If you ever get in a situation where you just feel like you can't do it or don't want to do it, you can always put a PM in place at any time.
