While I do take into consideration all the relevant expenses when I vet a property I still like to see at least $200/door cash flow so I can more easily build up my reserves and have some money to work with.  

If I ever run low on reserves, I can easily transfer funds from my personal to rental account.

They easily double(or more) in value every ten years.

I did do a search a few minutes ago and I admit I can't easily find anything that prohibits it now-a-days.

Its a lot of work but anyway you slice it a management company is going to cost you 10% of gross rents which could easily be 100% of your net profits.

We work with a lot of OOS investors and showings, inspections, and lending can all be done remote very easily. 

Since then, my cabins have tripled in value - worth easily $800K or more, and have produced $696,XXX in rents.  

But they easily refunded all of my money without the slightest hassle. 

Not much to add to the good advice already written, exceptYour mom could easily get a reverse mortgage to pay for her care, then you and your brothers could split the equity left upon sale.

What I was trying to say in my response is the units will be easily move in ready on delivery of the property.
