OK, you are in a tough situation. YOu don’t qualify for unemployment because you didn’t have either wage or 1099 income. You had “rental income” — and that does not count toward unemployment, as you just found out.
But you should get a stimulus check — if you qualify based on total income. Have you received that yet? That’s the first step.
Next, contact your mortgage lender and request a workout or extension. I think it’s likely that you had a federally insured mortgage. So the lender must work with you. Contact them immediately, and ask them to add any missed payments to the END of your loan, without penalty.
Similarly, when your property insurance comes due, pay monthly instead of the whole year. That will lower the burden. There is likely to e a period to extend your property taxes, as well.
In the meantime start advertizing that condo for sale as a “Covid Bargain”! Transactions are still taking place these days — as most closings are done virtually. Get a realtor who is active in your area. Getting the cash from that property will tide you through with the other rental.
And the renter who is not paying should sign an agreement that they will repay a certain extra amount every month over the next 6-8 months. That protects you legally if you eventually must kick them out for non-payment. Create that agreement and ask them to sign it.
What you are doing is “buying time” for the economy to recover. It’s better than sitting around and worrying. Take action now.
