It´s a small amount and going back and forth with a tenant on something like that, insinuating they have to pay because they are too dumb to figure stuff out could create bad blood over nothing.

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.

I know they have dock rentals everywhere but they don't usually include the vessel as well.

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.  

Also US population has much higher obesity rate (high blood pressure) and I saw somewhere this fact alone could contribute to the higher death rate than S.

IT is in my blood.

The "ship" is a much larger ocean-going vessel and you are likely never to be the captain.

The LLC is nothing more than a vessel to hold my real estate funds within and doesn't provide any services or sell any products or actually generate any revenue. 

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.
