In addition, there are 3 other adults living in the house, one of which, she mentioned has a job too. 

If you're an individual investor who owns or will be buying a single family home to rent in Metro Phoenix (and other booming Sunbelt states), good news: the big dogs with their legions of analysts think you're making a smart move...because they're doing it too.From a 10/19/20 article by Mark Heschmeyer of CoStar News:"Young adults have been fueling demand in the urban apartment market for several years.

I rent a townhouse to three adult college students on three individual leases co-signed by their parents.

Pre-COVID, I would have estimated it to rent in the $2,600-3,000 price range.Likely tenant would be a family with adults who are either govt employees or govt contractors.

I'm not an adult yet so I don't know much about basic finance and how the economy works.

Every adult generally has an automobile, so at a minimum this is needed to control parking and traffic.

We don't require them to carry renter's insurance because I expect our tenants to be adults and make those decisions for themselves.

My goals are to have some STR's in places I'd like to stay at as an option, have the rental income help me reach FI/RE and have multi-family units I could pass on to my 3 children once they are adults.

I have an Ohio LLC (single member-disregarded entity) that is 100% owned by a Wyoming LLC (single member - disregarded entity) that is 100% owned by an Australian Discretionary Trust.I am of the understanding that the Australian Trust is considered a Grantor Trust by the USA and that any taxes due from my Ohio LLC are passed down the line, first to my Wyoming LLC, then to my Australian Trust, and then to the Grantor of the trust.The Australian trust has as its trustee an Australian company (Corporate Trustee).I am the sole director of the Corporate Trustee.The beneficiaries of the trust are my my wife & I, our adult children, grandchildren & any as yet unborn heirs.So my question isWHO IS THE GRANTOR ?????

And don't think that rules or threats will help.Patch the holes and be of service.If it's a common issue, then you decide if you need to get restrictive.Good luck and remember that when we were kids, adults were stupid too!
