My typical guest is a set of grandparents, adult children and a set of kids, all of whom want to visit the Space Coast in general and the beaches in particular. 

I would like to rent my house and we would live in his (plus children from previous relationships).

We moved out-of-state (from Maryland to Colorado) to help our children with their children.

Add on the risk of getting other tenants or their children sick, and the financial risk compounds. 

Or doing the things that might help our children when they grow up.

My aunt wasn't Married or didn't have children, and both of her parents have passed has well.

How will you differentiate yourself from the people twice your age that have bought/sold their own homes many times, know what it's like to be a functional member of a community, raised children, owned businesses, worked a 30-year career in corporate America, lived through the housing crisis of 2008, and earned more than a few battle scars in life?

There are too many variables in each situation to say whether your tax professional did everything he or she could to reduce your taxable income through depreciation, improvement write offs and governmental administration changes, but you are asking the right question.My wife was an accountant before leaving the professional world to focus on our rental business and our children.

The cousins are not children of the aunts, so I don't know if there will be any issue there. 

So here, I had a family with 2 small children and no hot water for 2 days.
