Rental Property vs. Physical PMs

We have a rental property that has depreciated in fiat value.

Should we:

A) Sell the rental property at a loss and then take the equity we have and use it it to invest more deeply into physical PMs?

or

B) Should we hold the rental property, wait for inflation and then pay it off with the gains we receive in PMs that we already own?

Short version of the problem: What's more likely to be profitable: "Gains from low interest rates and eventual inflation" (rental house situation) or "Gains from PMs" (sell rental at loss and buy more PMs)?

I look forward to reading your advice.
