Description

*CALL FOR OFFERS ON MARCH 28th*
We are pleased to present the Westgate Apartments, a pride of ownership 31-unit asset in the highly desirable market of Simi Valley. The property is currently being operated as a 55+ community, but all covenants have expired and a new owner may choose to operate it with traditional tenants moving forward. The current 31 units on site are operating 88% below market rate. The property is also eligible for SB1211 allowing 8 detached ADU's on the property and 1 attached ADU for a total of 9 new 2 bed + 2 bath units, which would increase the gross income upside 167%. It is very rare to find a 1980's vintage asset at only $183k/unit. With the current in place rents the cap rate increases to a 8.1% after factoring in 1M in build costs for the 9 ADU's. Once all units are rented at market and ADU's are built, assuming a cost to renovate and build of $2.1; the property will operate at 10.56% cap rate and a 7 GRM. The property is fixed with common area amenities including a rec room as well as outdoor areas for grilling and socializing. 1850 Williams St is located in the heart of Simi Valley - just minutes away from restaurants, retail and supermarkets. This deal is perfect for investors looking for value-add, pride of ownership assets in a good neighborhood.
This property is off market, which means it's not currently listed for sale or rent on Trulia. This may be different from what's available on other websites or public sources. This description is from September 30, 2025
