Picture this: coffee on the screened porch, a stroll to the beach and marina, then an afternoon by your own in-ground pool. This Bay St. Louis gem pairs a 2,260 sq. ft. main home with a charming 1,208 sq. ft. guest house, for 5 bedrooms, 4 full baths, a sunroom and plenty of room to spread out. The lot stretches from Main St. through to State St., and the guest house has its own separate entrance and parking on the State St. side, so guests come and go without disturbing the main home. It's a natural family compound: room for in-laws, adult children, or visiting family, with everyone close but still private. The guest house also has strong Airbnb/VRBO potential. Visitors love staying in walkable Old Town near the beach, restaurants, shops and festivals. Private patios, lush gardens and small-town coastal charm complete the picture. Homes like this rarely come along, so schedule your showing today! ## Location - **Address:** 331 Main Street, Bay Saint Louis, MS 39520 - **County:** Hancock - **Neighborhood:** First Ward - **Coordinates:** 30.312875, -89.332216 - **Google Maps:** https://www.google.com/maps?q=30.312875,-89.332216 ## Virtual Tour & Media - **Video Tour:** https://www.propertypanorama.com/331-Main-Street-Bay-Saint-Louis-MS-39520--4166299/unbranded ## Listing Agent - **Name:** Tiffany Lord · **License:** S56098 - **Brokerage:** Keller Williams MS Gulf Coast - **Broker Phone:** (228) 275-7500 - **Listing URL:** [View original listing](https://www.realtor.com/realestateandhomes-detail/331-Main-St_Bay-Saint-Louis_MS_39520_M73881-04740?f=listhub&s=MGCMLSMS&m=4166299&c=propsimple) ## Photos ![331 Main Street - Photo 1](http://lh.rdcpix.com/21e94de6a25f3b53c9b2a90b05b55861l-f3113392083r.jpg) ![331 Main Street - Photo 2](http://lh.rdcpix.com/21e94de6a25f3b53c9b2a90b05b55861l-f4008579381r.jpg) ![331 Main Street - Photo 3](http://lh.rdcpix.com/21e94de6a25f3b53c9b2a90b05b55861l-f4253283839r.jpg) ![331 Main Street - Photo 4](http://lh.rdcpix.com/21e94de6a25f3b53c9b2a90b05b55861l-f3864696321r.jpg) ![331 Main Street - Photo 5](http://lh.rdcpix.com/21e94de6a25f3b53c9b2a90b05b55861l-f3198153873r.jpg) ![331 Main Street - Photo 6](http://lh.rdcpix.com/21e94de6a25f3b53c9b2a90b05b55861l-f1499844981r.jpg) ![331 Main Street - Photo 7](http://lh.rdcpix.com/21e94de6a25f3b53c9b2a90b05b55861l-f3711787268r.jpg) ![331 Main Street - Photo 8](http://lh.rdcpix.com/21e94de6a25f3b53c9b2a90b05b55861l-f1886919712r.jpg) ![331 Main Street - Photo 9](http://lh.rdcpix.com/21e94de6a25f3b53c9b2a90b05b55861l-f3207249232r.jpg) ![331 Main Street - Photo 10](http://lh.rdcpix.com/21e94de6a25f3b53c9b2a90b05b55861l-f1462269095r.jpg) ![331 Main Street - Photo 11](http://lh.rdcpix.com/21e94de6a25f3b53c9b2a90b05b55861l-f2731338194r.jpg) ![331 Main Street - Photo 12](http://lh.rdcpix.com/21e94de6a25f3b53c9b2a90b05b55861l-f1069452706r.jpg) ![331 Main Street - Photo 13](http://lh.rdcpix.com/21e94de6a25f3b53c9b2a90b05b55861l-f3334449782r.jpg) ![331 Main Street - Photo 14](http://lh.rdcpix.com/21e94de6a25f3b53c9b2a90b05b55861l-f3590504961r.jpg) ![331 Main Street - Photo 15](http://lh.rdcpix.com/21e94de6a25f3b53c9b2a90b05b55861l-f1608140101r.jpg) --- **MLS#:** 4166299 | **Updated:** 2026-10-29 **Source:** listhub *Copyright © 2026 MLS United.
