refund security deposit or not?

[Shannon Trivett]

On March 13th my tenant told me his intention to purchase a home. His 6 month lease was terminating on the 31st and he wanted to know if he could hold over on the weekly bases. 

when I questioned it he countered with  "or do the month"

later he informed me he would pay April. 

I was able to schedule an open house for the 21 and 22nd. At the end of the OH tenant verbally informed me I could not have anyone thru the following weekend because they intended to move all their stuff out to avoid paying for April. 

I have not been able to show the apt. since the open house and I've gotten many calls. 

Sunday evening he also informed me there is a broken storm window in the bathroom. presumably a neighbor kid hit it  with a stray shot form a bb gun.

1. how would you handle April rent?

2. what about the storm window?

Thanks
