They house was in perfect conditions when I rented it out to him.Do I need to do any kind of written warning or beef up my lease extension form?

Don't get too hung up on losing the bid when it happens, and just keep repeating.The menu looks huge, but if you know you just want beef or salad, you can quickly narrow down your choices.

Hi Ben,A brewery huh...You probably have something else in mind. but when you say Fort Collins BreweryI envision a Brewery/public bar with the bar having 12 foot high ceiling to floor windows on one side (on the side of a mountain) with a long expansive unobstructed view of the lower lands below.With a 40 foot deep deck on piles with chairs and tables outside in front of the large windows.And inside chairs and tables plus 6 premium raised up horseshoe booths that go for $20 extra just to sit there and enjoy the view--and buy alcohol and food.The bar serves high quality skin on hot dogs, fries cooked in beef tallow, pizza with  ton of cheese on it, high quality fried cheese sticks, and hot wings.The interior color scheme is dark brown wood and burgundy Naugahyde with nail trim.With some salt blocks put out to attract Elk to the area.There is a large steel building on the property with it's own parking lot for rental for wedding receptions, which includes a bar (due to the liquor licence)It also has a nice view and flowery repose area for wedding pics with the beautiful view as a background.Customer base not aimed at the College level (animal House crowd), but a nice place, a destination, that if someone is going to visit Ft.Collins--this is "THE" place to visit (and spend money at).But with Covid...public gathering places...hmmmm .... hmmmmm(???)

Even if they do pay rent the property is as likely as not to get shot up in a "street beef". 

Maybe a city where you can find a good Taiwanese beef noodle and a good South African bobotie?

It makes me want to beef up my VRBO bookings.

That said if she has taken over common areas you may need to beef up the lease on common area use and house rules to be sure the things she is doing are covered. 

Of course, cash flow is also a byproduct of expenses.

Even better, is paying and physically being among active investors, rather than just learning Online or from books- it takes it to a whole other level.A byproduct of this, is you surround yourself with successful, self-motivated people.

I would meet with them and see what their beef might be and see if they have a solution that might work for you.
