Problems with finding tenant, vandalism, and theft

[Sam Lee]

Hi all,
My family has a house in Tulsa, Ok that we've been renting out for the past 5 years but now have come across problems. I don't personally own the house but thought I'd ask for opinions and advice on the matter.

Problem #1
The house has no tenants. There have been no tenants for almost a year. I know that there is a management company working for us...but no tenants.

Problem #2
Since the house has been vacant, we have received letters from the management company about vandalism including windows shattered, and busted garage doors. Also, a fridge and TV have been stolen out of the house.

Facts:
Rented out to section 8 tenants
3 bed 1 bath SFR
Location: Tulsa, OK

Any help would be appreciated. If you need any more information, Ill try to respond as quickly as I can.
