Software for tracking both rentals and seller financed notes

[Nate T.]

Can anyone recommend a good property management software solution that tracks seller financed loans (i.e. properties that we have sold with seller financing), along with tracking the rentals?

We are currently using Excel for the most part for tracking the rentals, and using a third party account servicing company for tracking most of the seller financed loans (Weststar).  I would like a software solution that handles both.  And ideally the seller financing tracker should handle borrower escrow accounts.

I appreciate any input! :)
