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!

We used to have problems with slow drains in the 1970s house I live in (3 bathrooms, 6 adult roomies). 

I want to be very careful with this situation Well this is next level - an adult with a gun threatening your tenant and coercing minors into vandalizing a property.

As it is now, most places restrict the number of unrelated adult renters to way lower than the number of people allowed as a family. 

Do not forget to socialize and be a young adult!

I know some adults who need this book!
