Personally I use PropStream for both physical and virtual driving for dollars (and many other things).

For instance, lets say broker, for some odd reason, makes assurances as to title or some physical aspect of the property.

If you have strong contractor connections and someone who can physically go to the property on a short notice, you may be able to make it work.

Again, many contractors have the best of intentions but if they are on a tight budget or timeline they will make decisions differently if you are not physically there constantly to check their work at all stages. 

I had a similar situation where a property did not have any physical indicators, but a test was done anyways just to be sure for the same reasons you're concerned (big remediation bill).

@Chris Smith  The Tax Claim Bureau has a physical paper file at their office which shows the notices. 

That means, I have physical receipts in a folder and it is a fun game where I have to do my taxes before the ink fades off of them.  

This section is about the physical condition of the property and to a certain extent, the neighborhood.

Either only or physical location? 

I am interested in Online programs since I am not physically in Florida unless there is a class offering in New Jersey that I can take..as far as I know it is not an option.
