Wondering what homes are open in Watertown and Waltham this weekend? Patch is too, and we're hoping our readers and real estate agents can fill us in on any open houses happening in town.

If you know of one, or a few, let us know. Here's how: 

• Click the "upload photos and video" button underneath the picture at right
• Upload a photo of the home
• In the caption, tell us the home's address, list price, number of beds and baths and day and time of the open house
• Also feel free to leave the info in our comments section

Thanks for contributing!
