Sell unwanted stuff that you probably have around your place or your parents.

Being on the receiving end of a lot of unwanted letters and phone calls is annoying, think telemarketing on steroids. 

That way, you can just give 30 days notice to end a tenancy, as well as 30 days notice to change any rules, etc.The things that usually wreck roommate situations is unwanted guests, not cleaning up after themselves, messing with thermostats, stealing food.Some of those things can be pretty easily dealt with - like including a weekly cleaning service in the rent, putting little apartment fridges in the rooms.But, inevitably, there will be a roommate who you will want to get rid of, so having month to month agreements is the easiest way to get rid of them.  

It would be cheaper for you to pay for a fat life insurance policy for them.I don't know your rental market, but if the normal market there is such that you can't get a unit rented for 6 months to a year, it's time to sell it and at a loss if necessary.

A) It's not exactly what he said orB) It's BSThe big guys 25+ years are still all quite fat and happy with a ton of debt and units.I'm not doubting Dave at all, since about 80% of people mis-handle debt and a cash-only budget is what they need.However, if you understand the power of using OPM money (ie you borrow o$1 at x% and get a return on it >>x%) it is a major tool in growth.Now if you're 60 and unwinding, I understand. 

Everyone should boycott them anyway, based on fat content.

Then they cook meth in the house or some other unwanted thing.

It's leaving me with unwanted vacancy and incredibly inconvenient extra payments on spaces i'm trying to fill.

I know if I hired one to take care of a property, there would be a fat bonus at the end of the year if there were no problems and I was making money because of their good management.

I really wish that you can maybe replace their A/C to a new one but you have a big fat wall in front of you.
