Your best bet is to seal up & repair everything you can, keep vegetation away from the building, make sure there's no food around (like pet food or bird seed) & that the tenant keeps their place clean & food-free.

We have chickens, goats, sheep, and a large vegetable garden.  

Maybe a hint of rotten potatoes or vegetables.

From a business standpoint, the company wouldn't care, as moonlighting isn't against any rules.Ironically, I've had a vegetable business on the side in the past, and all my bosses/colleagues knew about that and thought it was cool.

Grow a small garden or hit up a farmers market and buy your protein right, Drink water, etc.It doesn’t take much knowledge or education to do any of this it’s all very simple and common sense but most people have lost the ability to be disciplined and hold themselves accountable.  

I am open to the idea since I am owner occupying a duplex and I myself will be having a vegetable garden in the back yard.

In Utah I'm trying to keep all the vegetation alive, in Michigan I'm trying to keep it cut back.

Romantic" - Outdated and overrun with vegetation."

if there is income -- you can get USDA ( business loan ) -- pretend that you will a farmer for few years -- OR have seller get loan on that portion of farm acres -- and give to you to fix up the house and pay up back taxes -- meanwhile have your current house on market for sale -- now go buy that fixed up house and move in -- then --if you wish, divide the land in several small parcels and sell at some profit and pay off the loan -- keep 30 -50 acres FREE and Clear for your future -- Retirement income -- you can lease one or two acres parcel to local people to grow their own vegetables --You are No Longer a Farmer.
