Post a full RE sell vs rent case study (sticky at the top of the forum) and you'll get better advice.
Do you currently (or recently) live in the house?
Is that gross rents? Why the range? Do you charge variable rent month to month?
Or do you mean *potential* rental income?
In general, that's a bad rental - unless you're *netting* $3k+ per month after all expenses (ie, PITI, management, vacancy, capex/maintenance, etc) in which case it's not bad. At the high end you don't need to hit the 1% rule to make good money in many cases.
If you live there now, I'd sell it just for the capital gains exemption.
