Property Description
**Investment Property Opportunity with Value-Added Potential** This property is currently appraised at $4,050,000 (MAI Appraisal). As a short-term rental, the estimated value increases to $4,555,000. Additionally, the large lot has the potential for constructing an Accessory Dwelling Unit (ADU) in the back, which could push the total value of the property to well over $6,000,000. You won’t find other properties on the Peninsula that offer this type of opportunity. This rare investment is just steps from the beach, located in one of Newport Beach’s most desirable coastal communities. It features a two-car garage and offers peak ocean views from the balcony. The property is conveniently situated just a quick drive from all that Orange County has to offer, including: - Pelican Hill Golf and Resort (10 minutes) - John Wayne Airport (10 minutes) - Angel Stadium & Honda Center (15 minutes) - Disneyland (20 minutes) - Knotts Berry Farm (20 minutes) - Laguna Beach (15 minutes) - Huntington Beach Pier (5 minutes) - Newport Harbor Fun Zone (3 minutes) - Fashion Island (5 minutes) - Segerstrom Hall & South Coast Plaza (15 minutes) Furthermore, this property presents an excellent opportunity for use as a primary residence. The upstairs can serve as a living space while the lower unit can be rented out as an income-producing property. Both units are currently rented on a month-to-month basis.
