Lee, It is quite unlikely the lender is watching/scanning the corporate registry for changes to directors/ownership structure, etc of companies which from which they have subscribed mortgages, though with today's computer search methods and big data processing, it is not outside the realm of possible.Technically, as a stakeholder / creditor, the lender should be notified at the time the company is sold / experiences a change of controlling ownership.  

Data from Charlston Trident association of realtors.

C class properties if you look at historical data points really don't move in value much... the only way they go down in value is failed landlord syndrome and the house is trashed then it gets tied up by a wholesaler who sells to a rehabber who sells to a end user..

I tend to get to overwhelmed with all the data or just looking for that PERFECT deal.

I also have a colum to the right of all this where I put the exact amount of each deposit the tenant makes and the dates along with any notes.I keep up with the Magistrate for each property, tenants names and numbers, trash day AC filter size and other data I need to keep up with for each property.

I was looking at some data recently on new construction sales in my area, and couldnt believe the disparity between the prices and subsidies when an agent was used, and when the buyer bought directly from the builder.  

This is an appraisal using the public records and MLS data.

Being in the background check industry I need to help you understand something, some of the information you are getting from your service provider(s) could be out of date; as it relates to data like criminal information etc.
