Also, you may want to consider using a note servicer (in my area many title companies offer this service). 

The tenant was placed by the property management company I was using at the time, and they either didn't collect information for additional contacts, or didn't pass it along. 

Notify your mortgage lender and insurance company of the transfer of ownership to update financing and insurance coverage.

People call me all the time asking about such companies.

Smith, Grantor, hereby sales and warrants unto Tom, LLC, a Limited Liability Company created and existing under and by virtue of the laws of Washington, whose principal place of business is 123 Smith Street, and Mike LLC a Limited liability Company created and existing under and by virtue of the laws of the State of Washington, whose principal address is 456 Jones Street, Seattle Washington 12345, Grabtees, as Tenants in Common.

I could probably rent it for $750-$1000 per month over what the standard monthly costs are right now (not including vacancy, maintenance, management company, etc).

A turnkey could make you sign a contract when buying a property that states you cannot say anything negative about the company.

Has anyone heard of this company?

I think turnkey rentals are a good option, but you have to be very careful with turnkey companies.

How do I find a title company that will know how to handle seller finance or subto?
