Can't speak to 'crazy', and perhaps not even to "will this rental generate cash flow"... but as the Magic 8 Ball of rentals says:
Signs point to No.
SFH costs are beyond mortgage: Taxes, Insurance, Repairs, Property Management, HOA fees (if any), etc.
Without actual numbers, it's hard to say. You can use Zillow's 'Rent Zestimate' as a starting point to see what you might be able to attract in rents. Depending on how much your house has appreciated, you may be better off selling. All the best! MFB
