I also can’t use a FHA or any loan that requires me to stay in the unit for a year. 

If you're married but your spouse does not work and is on your primary mortgage there are still ways to work around this.Seem appropriate to say I am NOT a lender but I do have a fair bit of knowledge on this as my wife and I own 12-doors in Detroit but live in CA.Beyond the fact that you could have 20 conventional mortgages between you and a spouse, how you should proceed is dependent on your goals.Would 10 SFH's be "enough" to reach your goals?

How's it going, I am a dentist working in Boston, MA with a decent amount of book knowledge in REI.

I’ve been to a few of the LAREIC events and Lloyd and his team provides so much knowledge.

Most of these cards don't show up on your personal credit report so your 700 plus fico score will stay that way. 

Or they could stay the way they are for a lot longer than expected and cause a lot of work and effort for no profit (which is a loss after considering all costs).

Contact Mom, let her know she continues to be financially responsible for the premises as long as he continues to stay there. 

She is having other people stay there (against the lease),  do they automatically become trespassers at that point in which I can have them removed by calling the police?

That gives me a little bit of peace of mind in case my property stays vacant for a little bit while I get it ready, but I also don’t want my primary residence to be on the line for too long. 

Your experience as a seasoned landlord with 9 rentals across 3 states brings a wealth of knowledge to our community.
