abondonn properties with no real leads help

[Mike Sagesse]

Hello Folks 

Heres the deal (no pun intended) i'm a realtor and every once a while a client walks into the office and is a tenant and their landlord has abandon the property. in this particular situation the landlord who left the property isn't the owner but his son the actual owner has passed away, so my client who walked in says shes has been having a hard time with the son who hasn't done much to up keep the property and has just been taking the rent till one day he decides to up and leave. so now shes looking for a new place to rent but now the same time this 3 family home sits vacant shes the only tenant till she finds a place. 

 so far i've  looked into it to see whats going on. So far the home is currently in lis pendas  deed is still under the late fathers name. the only thing that confuses me is the fact that the property taxes are going to a random address to this other person who is actually paying the taxes on time. 

now i don't know what my next move should be, any suggestions or ideas of what i should do next cause i'm stuck..... i hope my story makes sense

I think your first move is to contact the person who's paying the taxes. He/she should be able to give you more information on the property and possibly the son as well. 

Do you know if there is a mortgage on the property? If so, then I'd contact the bank to see if the payments are being made. 

Have you run a prelim?
