Can the rates increase at a dangerous rate since they aren't fixed?

Your municipality probably has laws against the negligent discharge of a firearm and/or a tenant that poses a danger to the neighborhood.

It's not uncommon for folks out of surgery to be given blood-thinners to help prevent dangerous blood clots.

A consumer tenant/buyer for more than 6-months is legal, but dangerous and highly discouraged because compliance is almost impossible and the statutory penalty prohibitive.Also, you will have difficulty evicting if the judge knows anything because you (landlord) must show superior right to possession. 

I was hoping to "house hack" my first property (preferably a small multi family; less that 5 units.. but a SFR would work as well).I only want to buy in an area that i would live in myself, i dont have high standards but i dont want to live somewhere of poor quality or in a dangerous area either. 

I've met with some very interesting and possibly dangerous situations.

He seemed to know as much as I do about SDIRA & 401(k)s (Limited and dangerous "knowledge" ;-) He says he is on BP so I will forward this link to him.

Beware: this tendency carries the very real danger that we may come to believe we are living in a world that is very different than it actually is.
