There are 3 houses in my neighborhood that have been or are on rent and every one of them has a rent payment much higher than you could get any of those homes for (including mortgage, property tax, insurance, maintenance, etc). The people living in them either can't get financing or need a short term place to stay (one man makes good money but is in the middle of a divorce for example).
I own a few single family homes and none of my rent is less than the mortgage which includes insurance and property taxes. All of the rents run about 20-30% above the cost. If I cant cash flow the property I sell it. I'll be honest and say how surprising the demand is for these places. Put a house on craigslist and within hours I have showings and can usually get somebody passing a background check and have a signed lease within a week.
