There is definitely a learning curve to real estate investing and it sounds like you have a great foundation.   

Concrete drives, patios, foundations, etc.

@Toni Fowler It would probably depend on where the house was located, is it in a park or on a parcel of land with a permanent foundation?

I now have a great foundation of knowledge and my courses in AZ covered the basics of financing, property management, the different career fields in real estate and in addition I had that added bonus of having an investor as an instructor which was priceless!

If a mobile home is on a permanent foundation, it is considered real estate and could actually appreciate in value?

True they have nothing about selling but it will give you a valuable foundation in law.

The property also has a pest problem (termites, foundation ants and mice).

Second questions is regarding a foundation issue for a ranch style house.

Elizaveta, I will take a crack at it since no one has responded yet. 1) My first deal was a fairly in depth rehab which included foundation repairs, window replacements, garage roof replacement, electric work, plumbing work, floor refinishing, and a lot of the things we do to almost all our rehabs (new light fixtures, new outlet covers, new appliances, new doors, etc).

Once you've worked your way through the guide and the links off of it, you'll have a good foundation.
