Not sure what you have done to try to resolve the situation.  

A lot of times there are some title issues with these types of properties that you'll have to clean up, but they are generally fairly easy to resolve.

Your personalities should be compatible.

On the other hand, if a client has an issue with a property 5 years or even 10 years after they purchased it, they come to us and we own resolving it.

Hey @Sean OToole, Wanted to mention I had some billing issues with the service initially, but your awesome staff helped resolve them quickly!

If not, Im not sure how you could resolve a dispute short of suing them. 

Occupied by Past Owner in one unit, the other unit is empty.I have hired a property Management company to complete eviction - Upon receiving Eviction notice, Past Owner / Tenant went to the Property Management office and insisted that she still owns the property, refused to sign a lease, and stated that she won’t pay rent for her own property.Property Management company stated that this will not be resolved without going in front of a judge and told me that it can be filed at the end of the month.How long with this process take?

I've logged over 30 hours of phone time with their "management" trying to resolve the issue. 

They won't release the rent payment to us until its resolved. 

That will resolve all issues with passing on the investments and investment company to the son when ready.
