Anyone staying longer than that must submit to a full background check to be added to the lease.If you don't want this guy there, and your lease provides an out, simply state that the boyfriend is not allowed to stay, that if you find that he is staying you will deliver a notice to cure or quit and then follow up if when you discover the boyfriend still there.If you do decide to add him (he's going to be there whether you add him or not) then absolutely do a full background check and credit check.

As a result, it is more cost effective and less hassle to simply buy the insurance and be done with it.  

Something like:  During the period from the date of execution of this agreement through and iuncluding the closing, Owner shall not enter into any leases or extend any leases covering any part of the Property without the written consent of Buyer.

We don't have any tenants that simply don't pay, they just enjoy paying the late fee, it seems.

You simply need to convince the bank that you will actually Close....they’d rather have a full payoff than foreclose. 

I simply refinanced it into my primary mortgage.

Oh and as for the orphan days, I simply offer steep discounts to keep the cash flowing.

It is currently rented out, but given there are no pictures and we can't enter that these are problem tenants.We're worried that we might be getting in over our head since we don't know the condition of the inside.

History does not repeat itself...it simply rhymes. 

At least that is my understanding.Do I simply raise the rent enough to make her want to leave, but not an outrageous amount?
