Not one of them has ever said it was a bad decision buying their property I would say all of them would probably say it was the best thing they've ever done.Here's my plan take from it what you will (I wish my parents knew enough to do this).I have two kids and soon as they turn 18 I will have them buy a 4-unit using FHA 3.5% down and a blood relative (me) as a non-occupying co-borrower and source for down payment.

If real estate is truly in your blood I would highly recommend obtaining a sales type position either as a Realtor or as a mortgage broker.  

Politics will 100% get involved, that'll happen the closer we see some blood dripping versus November.

Honestly, these issues you've aired, a cold-blooded "Landlord" wouldn't loose a wink of sleep over.

Do you lose anything by greater circulation?

@Tracy ScottScour the HOA docs for wording involving occupancy such as, "not more than three (3) persons not related by blood or marriage living and cooking together as a single housekeeping unit."

IT is in my blood.

Cash is like the blood flow through your body.  

Some of my family members have RE investment properties and I guess it's in my blood!

I had to pay it in money, blood, sweat, tears, overcoming fears, frustration, hard work, and tenacity.
