If you want to track homes as they come on the MLS and follow price changes or status changes, you can ask any TMLS Realtor to set you up a complimentary search with updates for your street. Many, myself included, will do that with no strings attached, No Hassle, and no pushy phone calls or emails to bother you.
If you want to not bother an agent, I let people use my site regularly, and I don't bother them until they contact me, if they even do contact me.
Just click the city, and enter the street name, and you will see homes that are on the market. You can also input your email to receive automatic updates, if you would like. Still, always "No Hassle."
