On HAR.com you can search for leases at this link, http://search.har.com/engine/dispSearchClass7.cfm
You may need to limit your search criteria to just one or two search criteria. In certain areas of Houston there is very low inventory of available homes. It would be more efficient to contact a Realtor to assist you in your search.
Try altering your search criteria. If you have put in everything you are looking for and nothing is coming up, your criteria could be took specific or there just may not be anything available at that time. I highly suggest contacting a realtor who specializes in leasing in your area of town and also carries the ABR designation.
On the HAR.com home page there are different options near the top of the screen. Find a Home, Find a Rental, Home Values, etc. Click on the "Find a Rental" button just below "44,081 REALTOR Listed Properties..."
I hope this helps. If you need further assistance you can contact me directly. Good Luck!
