I discovered a guideline that prevents lenders to loan to Condos that have master homeowner's deductible > 5%. 

Additionally, there is NO verbiage that states the Landlord cannot impose verbiage in a Lease of a non-pet owner to prevent future pet ownership...

I just recommend you choose the house/market carefully to prevent regret in the long term.

Applying those principle, focus your energy on doing the preventative things on a day to day basis that reduces the risk of claims from occurring in the first place  (siginign vendor agreeements /collecting insurance certificates) and carry appropriate levels of insurance.

On the last comment let's say the title company missed an easement which effectively prevents the intended use of the land.

It can prevent them from buying a house.

More turn overs, more tenant drama, a bit more effort to furnish common areas, more move-in/move-out damage (some investors do fully furnished to prevent this).  

In fact, locks may be a violation of code because a locked window prevents someone from escaping in case of fire.2.

I'd start with cash for keys but if that didn't work,  seems like it may take 3-4 months to evict a person,    my big question is getting liability insurance on the property.I get that there isn't much I can do preventing the previous owner from trashing the place  (she is 60+ so I doubt she's taking a hammer to the place)   but I do worry that if she or someone else were to get hurt prior to an eviction and sues me.Can you get insurance on a property under these conditions?

Trying to figure out if this is natural settling or we should provide reinforcement to the beam to prevent further settling.
