What if ….. You could go back in time to a simpler time. Pick the best LOCATION on a huge lot with only 1 neighbor and create your dream home. Or maybe add a second home on that lot for family or income POTENTIAL. The city of Costa Mesa calls that “Legal non-conforming” and we call that 345 Costa Mesa Street (2nd electric meter is referred to as 1915 Raymond Avenue). Many, many years ago the original owners did just that and now you may be the recipient of their forethought. This large approx. 2134 sf single level, single family "multiple" building has been utilized as 1, 2 and 3 separate units through the years. Use your imagination to make it your perfect vision. Front home has 3 bedrooms and 1 full bath and back home has 2 bedrooms, one full and one 1/2 bath. 3 separate entrances, a two car garage plus a parking pad for 4 additional cars. Alley access and 2 permitted individual meters and “What If” becomes “Wow”. See for yourself the endless POSSIBILITIES.

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.
