Property Description
Tired of mediocre $3.5-6 million dollar houses in Cupertino on undersized lots with limited appreciation potential? Consider this unique opportunity in Monta Vista. Exceptional location. Looking for buyer that wants to capture $2 million profit/equity while creating beautiful peaceful residence(s). My lot allows new owner to build a custom 4,200 sq. ft. SFR (& some ADUs). It also allows, for example, a 3,000 sq. ft. principal residence, a large ADU and small ADU. The ADUs would be detached structures with lots of sunlight and you would have a private rear yard behind your principal residence. Or you might build two x 2,000 ft. houses surrounded by garden. That's three desirable alternates. These build-out options were not permitted until recently by Cupertino. This is a beautiful and private lot. Convert your stagnant appreciated equities into an investment vehicle for inflation safe, high appreciation, real estate in a privileged location. For total investment of approx. $5 million, projected ROI is $2 million. And you may generate over $100k/year income. Desirable location; high investment return; income; privacy; exclusivity; community; and natural beauty.
