Garden and/or produce as a value add

[Jason Sandegren]

Hey all,

I'm looking at beginning my own real estate investment with purchasing a duplex. My soon-to-be wife (this weekend!) has stated that one of the amenities she wants in a home is the ability to run her own garden. 

What do you think about offering garden space and/or selling fresh produce to tenants as a value add? Many of the posts and podcasts I've encountered have advised to find something that differentiates your property. As far as I can tell, this is not a common (or commonly marketed) amenity in my community. 

Does anyone have experience with this sort of value add?
