I'm struggling to find all the data I want, and when I do it's super difficult to get the data to gel well. 

You could make your own OO list - get the data from the county and compare the situs address vs the owner/taxpayer address field.The brokers charge a lot for data, so much so that it's really not an option for beginning investors. 

However, for the actual lifeblood of the business - cash flow- I found a website that looked pretty and offered some services that seemed to gel with what I needed at the time and signed up.

Attend some networking events and get to know some people, they can be your mentors and it may take a bit for that relationship to gel.

If you want a fixed 15-30yr low interest conventional loan most lenders will require a foundation and as @Jeffrey H.has stated it must not have been moved from its original situs unless it is coming directly from the factory or a dealers lot. 

so the people losing them are bombarded with letters much more so than normal non situs type letters.

But my understanding as a layman is that Nevada has charging order as sole legal remedy, so if you are attacked personally, and if there is no veil piercing or fraudulent action on your part, the asset of your Nevada LLC should be protected from you.However, if your property is in Florida, you will not be able to act in court as your Nevada LLC has no situs in Florida.

It is also reimbursing my vehicle mileage and medical expenses.Also you may need to have the entity registered in the state where the properties are as you need to have a local situs if you need to start an eviction or other legal action.

I'd hold if the situs is right.
