It looks as though there were 67 rentals in town that went to contract last month (March, 2014, for those not keeping up) and 86 single family homes. I’ll confirm those numbers and compare them to other years but it seems to me that that’s more rental captivity than average.
UPDATE: so much for intuition. The 2013 numbers for March were 81 rentals, 54 single families. Even allowing for my still trying to learn to use the new MLS data, it appears that the market for both rentals and sales is up considerably from last year.
