Do manufactured homes on deeded lots depreciate?

[Alessandra Verbena]

Is it just the psychology or stigma of manufactured housing? Looking to purchase a deeded lot with a beautiful modular-quality in a top manufactured home park in a beach town in California. Every bit as nice as a stick-built. My concern is depreciation. I will only get appreciation from the lot over the long-term. I am clearly buying at a top of the market price. Stick homes should depreciate after 30 years also, but that doesn't seem to be the case here in CA. How much do these manufactured homes depreciate over time? Should a high-quality modern manufactured home hold value?
