321 Rosemarie Pl is an excellent example of Townhouse living at its very best. The clever use of volume ceiling and a wide open floor plan make this 1988 Townhouse design far ahead of its time. This freshly painted and tastefully upgraded unit features: An upstairs Master Ensuite that is wide open to a roaring fireplace in the large Living Room below & an unobstructed views of nearby Suisun Bay that will provide you with hours of enjoyment on the spacious exterior deck. You will also love an eat-in Kitchen with high end SS Appliances. All 3 beds/ 2.5 baths are good sized with plenty of walk-in closet space. The Kitchen, Living Room, Guest Bath, Main Deck and Garage w/Laundry are all on the main level with the Master Bed upstairs and Bed 2 & 3 downstairs. The Seller is leaving a brand new Universal Workout machine, and this unit was recently inspected by HomeGaurd & all Seller repairs have been made. At $488,000 this is one of the best values in Contra Costa and it won't last long.

No weekly rateNo published rate within 7 days of this date.ZIP averages use publicly displayable closed sales from our licensed MLS feed, matched to the same ZIP and exact property type. Months with fewer than 3 sales are omitted; the current month is incomplete. Lines connect available monthly observations across gaps and do not represent measured prices in missing months. These averages are not adjusted for size, condition, or location within the ZIP, and are not an appraisal. Feed coverage may not include every sale. All available shows the available home and ZIP history, with mortgage rates over the same dates.
Mortgage benchmark: Freddie Mac Primary Mortgage Market Survey®. © Freddie Mac. Weekly national 30-year fixed rates, not APRs or a loan quote. Actual terms vary. Methodology changed in November 2022. The chart does not establish that interest-rate changes caused a home’s price changes.
Lines connect recorded asking and sale prices. They are visual guides, not estimates of the home’s value between those dates.
No earlier records were returned by our current sources. This does not mean the home has never sold.
MLS records may be incomplete. Earlier asking prices are not sale prices.
