Opening home details…
623 Hamilton Street Costa Mesa is a spectacular fourplex investment opportunity. All 4 units are 2 bedroom/1 bath. Each residence has a 1 car garage plus ample additional off-street parking, washer/dryer hookups and private yard space. Very rare for Costa Mesa, the units are separately metered for water. With the tenants paying for water, expenses are lower for the owner. There are no rent control or affordable housing restrictions for these units. This site is well-located less than a block from Rea Elementary School and offers easy access to main freeways. It’s close to all the fine dining, shopping and eclectic entertainment that Costa Mesa offers. This site is also within the Mesa West Residential Ownership Urban Plan, which presents a potential redevelopment opportunity.

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.
