Right now, if you consider all types of properties (condos, townhouses and single family homes), 57% are available, 11% are considering tenants, and 32% have been leased in the last 30 days.
For single family homes, 54% are available, 13% are considering tenants, 33% have been leased in the last 30 days.
So basically just under 50% of the properties available are being rented. Of course, price and location as well as condition have a lot to do with how fast the property is leased. The better it shows, the faster it leases.
