You will have to gather more accurate operating costs (vacancy loss, taxes, utilities, insurance, mgmt fees, maintenance, HOA) to best determine potential future performance.

The down side is that STRs are more work, need to furnish it, pay for utilities and WiFI but in the right market (vacationers and business travelers) it could work. - If I were looking at cash flow as a really important important metric, I'd consider starting a business.

Be prepared to show a lease, some utility bill, or credit card statement showing you live somewhere else.
