If they pay the property tax and itemize, that's deductible.

Will the amount they pay you exceed the costs, including allowable depreciation? Would it be fair market rental rate?

A non property owner generally can’t deduct property tax, mortgage interest, etc.

The IRS has free publications that are good.

This is a legal question. You have no idea what the qualifications are of anyone who purports to answer. If you rely on an answer and it turns out to be wrong, it may cause legal problems for you. See a real attorney in person and get reliable advice. It will be well worth it. Any good answer would require more details than you have given, and, besides, there could be both federal and state tax implications.

Her husband had a heart attack n they were building a house so I was “property mgr”. I paid my share of property taxes, insurance but no rent..that’s how we decided n for tax time, I filed short form. No problem. Just keep it simple unless her name is on deeds. Worked for us. He’s thankfully recovered n I came back home.

You'll get informed information.

On an internet chat board, you have no idea of the quality of any advice.

Incidentally, we're sub-letting our apartment (legally) and we intend to declare the rent as taxable income. Why take chances?

Good luck!
