If you choose not to do anything then all your rights to property will be transferred to new buyer including mineral leases.  

My question, how do i find the owners for these properties if their is no data trail on the county auditors website?  

I can't say whether the state law assumes the contract is assignable by default if nothing is in there about it or if the state law normally assumed non-transferable.

Basically the owner gets the bill from the utility company and pays the bill, then they use a different company to take in the data from all the submeters collected from the BMS system to write their own bills to the tenants to get reimbursed.  

Should most of my current (and limited) knowledge transfer between them?  

Although, it would be helpful if she could provide some verifiable data about how many applications she gets when she rents a property, what percentage of evictions vs good stable renters she has had.

Always do transfers through an escrow agent in the US (or Canada or Europe for that matter, depending on where you are based), who knows business in Mexico: never release any money, unless all documents, title, property clearing is in place.

Transfer it to my LCC bank account? 

Conventional lenders want to see operating data that supports the loan. 

Meaning the first lien could foreclose regardless of debt service being current because title transferred to a new party.
