A home you cannot visit can be left empty and looked after, or let to produce rent. Each needs somebody on the ground. Decide which you want, because it changes what you ask for.
Keep the title papers somewhere safe and copies where you can reach them. If you give somebody authority to act for you, do it in writing, for a stated purpose, and take advice on how it is done properly from where you live.
This guide is general information, not legal, tax or financial advice. Rules differ between states and change over time, so confirm the details that matter to you with a qualified professional or the authority concerned before you act.
