You have refrigeration, Air Conditioning, a smart phone, the internet, Air Jordans, two computers, take vacations, go to college, 37 flavors of ice cream, have 365 channels of TV (I didn't say they were worth watching ;-) health insurance, life insurance, fire insurance, auto insurance, home owner's insurance, SDIRA, 401(k), plastic surgery, viagra, fast food and can call the shots of just about anything you want to do or be.I grew up in a 790 sq ft house with 4 brothers, a cousin & aunt and my folks. 

I do wish you luck but I am giving you food for thought! 

I know their are single family homes can be converted to small adult care homes for adults needs minimal assistance and food preparation.

Food for thought.T. 

If that's the case, I'm not sure you want to be involved with that either.If they were running a consulting business or something not requiring people to come to the property, I'd be totally OK with that (that's like working from home), but you will have children coming, the health department for food, and a lot of other people you may not want monitoring your property.

Usually free food and free drinks.

It’s 99% of the time because tenants are absolute slobs leaving dishes in the sinks and food left out .

Also, having food storage and an emergency fund enough to cover 6-12 months can provide you enough time to regroup from many unexpected life changes.

It looks like the father cooks and the family buys their food as a way of " helping them". 

@Mike Neubauer I'm developing a Food Truck Park in Kahului Harbor and plan on opening mid February 2020.
