Property management company does not provide previous tenant's social security number

[Oleg Serdyuk]

A property management company is managing my investment property. The tenant left, owing a significant amount of money. As a result, I am not planning to continue working with that property management company. Now, I am working with a collection agency to recover the unpaid rent. However, the collection agency is requesting the rental application with the tenant's Social Security Number (SSN), but the property management company is refusing to provide it, citing the sensitive nature of the information. 

How can I proceed? 

Do they have the right to withhold this information even though the tenant owes me money?

Quote from @Oleg Serdyuk:

The Property Manager has a right to protect that information but you have a right to it as the Landlord. I would demand they turn over unredacted copies of all documents, including the original applications, driver's license, etc. If they are pushy about protecting the Tenant's privacy, tell them to send it directly to the collection agency which is legally bound to protect privacy at an even higher standard.

If the PM absolutely refuses, then I recommend you threaten to file a complaint with the State Commission. The threat of a complaint will usually get them to comply.
