I'll handle rehab cost, management and yearly expenses etc...and would like to build a nation wide company consisting of low income-luxury buy and holds, fix and flips, commercial, development and eventually branch out to vacation rentals as well.  

Some of which are national builders like DR Horton, Toll Brothers, LGI, etc.

The National Real Estate Insurance Group (NREIG) is really easy to work with and doesn't require repairs like that usually.

I would highly recommend NARPM (National Association of Residential Property Managers) to learn about Property Management.

I will let engelo pontificate on it.. being that he is famous there.. you may not have known it but he bought the cheapest home ever sold in All of Australia and made national news.. then they kicked him out of the country and he had to flee to the US were as we know we love imigration legal or not.

Lastly when I was newer in the business I was a Land ONLY specialist I sold smaller to larger Ranch style land and depending on where it was and how difficult it was to show standard fee's in those  days was 10% and on some of my deals that were 40 miles of dirt road back into Mendocino National Forest and took someone with my unique skills with maps and compass's to even find the land I charged 20 to 30% commish on those.

Read the book the 16% solution for a good general overview.My advice is don't take any of these types of national courses.

For tax liens you will have to have a national acquisition strategy, you cannot limit yourself on one or two states.
