It was pretty hard to find properties where the numbers and landlord laws made sense which is what ultimately led me to investing in Columbus, OH.The numbers and landlord laws out here made sense then, and they still do today.

The applicable law is the Fair Housing Amendments Act of 1988. 

Buying as a primary allows you to put as little as 3.5% to 5% down.If you do have any issues with the business down the road you can always use a DSCR program which allows investors to buy an property without having to show income or employment.

any legal issues I should know about?

Just debating to do it or not because I don't have any issues and don't want to pay $5 a month and have to constantly go check my mail at the post office. 

@Deonte Hill-  thanks ...trust your instinct ....yes - massive red flag . unless you have unlimited cash to  address  unlimited issues - be wary 

This is one of the reasons why I also worry about using something like this lease agreement without understanding the law.  

Shortly after I was advised by the utility company that there was an issue with my water that is indicating there is a massive leak.

Note that under the newest Prop 19 laws, the parent-child exclusion is generally only available for a property that was the parent's primary residence that becomes a child's primary residence within 1 year of the transfer.

I don't have much issue with this sort of thing.
