It is easy enough to stick to the facts about the deposit and damage, plus sending people over to do work after they've been 'fired'.

It was built in the 1950s and has a boiler for heat and window units for air.

I convert all of my houses to central heat and air as well.

Truth be told, they were grant tenants until they moved out and got upset about security withdraws due to leaving the place trashed (not damaged).

Tenant claims car was damaged got estimate stating 4800 in damage.  

I did a complete rehab on the property adding central heat and air, upgrade electrical, floors, and kitchen.

what must the seller do to sell the property to another buyer while still retaining the ability to sue the first buyer for damages, and the difference in sale price if necessary?  

Btw, I agree that deposits are--by definition--refundable unless the aggrieved party can demonstrate financial damages. 

I would like to learn about three types of scenarios that would seem to be of great benefit to a LL/PM if a tenant held renters insurance;Situation A (property damage): Tenant causes damage to LL property in excess of security deposit.

Also, have them put stoppers in sink drains, just to be safe.There's a chance they could be entering VIA the duct work/air returns as well.
