They sleep, take a shower, toss some fast food wrappers in the trash, and move on.

My grandfather willingly let a friend of a friend move into a studio apartment ADU in his backyard.It has been a couple of years now and she has piles of junk inside and outside of the unit and has also been throwing food scraps into the yard and into the pool.I believe her plan was to outlive him and acquire the property through adverse possession.Long story short, I'd like to hit her with a 3-day notice and start the eviction process ASAP.Is a 3-day reasonable in this situation, in San Bernardino county California?

I’ve seen it done and it’s food for thought as you market this property once you sign on your newest clients.

If this tenant tends to fry a lot of food and isn't good about not pouring grease down the drain, that would be a red flag contributing to the damage.

We're in the Blue Ridge Mountains so people come here for the hiking, outdoor activities and cities nearby that have great breweries and food.

Just some food for thought, but I typically find that clients get hung up on all the shiny objects in REI, and to be honest there isn't a better return on investment than house hacking!

One thing you could do that might really benefit you, is to find a small business coach (preferably one that knows the food/drink industry). 

FIBI actually gives everyone free beer, whiskey shots (If I saw what I thought and they pay for for food at an Italian restaurant.

Every fast food place in America is hiring right now.

And if, along the way, you decide to get into real estate you'll have that option.Hope this helps provide food for thought.
