TRUST SALE. This site is perfect for Redevelopment and is zoned R-2 HD (20 units to the acre) which we believe will support 5-6 new residences. Any serious developer should meet with City of CM planing officials for details. This type of redevelopment and re-gentrification is happening all over Westside Costa Mesa. The Seller will provide a reasonable Due Diligence time-frame for a developer; however, they would like to close on an un-entitled basis with pricing reasonable to that end. First time on the market since 1970. The 18th Street Cottages/Development Site has many options as redevelopment now or great value add play. There are (4) 2bd/1ba single story cottages each with large yard, single garage, W & D hook-ups, and separate hot water heaters. The improvements are situated on the front of a large 17,090 sq ft lot boasting a very large open area in the rear. The property and improvements need renovation and there is tremendous attainable upside with those improvements. The last rental and currently the highest rent is $1850 with the lowest unit rent at $1100. The front unit with very large yard is $1300 with a 12 year resident. There is one vacant un-renovated unit and that unit interior can be shown to a qualified and vetted investor/developer by appointment.

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.
