My girlfriend (100% new to real estate) is also obsessed and devours materials like no other!

It would be a good material to start here https://www.biggerpockets.com/courses/a-beginners-introduction-to-real-estate-investing

We put about $26k in materials into it.

If you put in no money, what guarantee do I have you will pay me back.This reverts back to the no money down stuff that has been promoted forever.

Then, you remove all of the damaged materials, and depending on what happened underneath, if nothing, then you're done.

Do you buy materials separately yourself or pay contractor for both labor and materials?

We have the local stores actually doing our shopping for us, discounting the items and then making arrangements with our maintenance team to come and pick up the material. 

There's lots of great material on it and it sounds like what you are looking for.

Be sure to check out the podcasts and other materials in the Education section.

@Ryan Andersen the most comprehensive guide to understanding, purchasing, and operating mobile home parks is from the Mobile Home University website (coincidentally authored by Frank and his business partner who responded to you earlier - he's not a self-promoter on BP so I will happily do it).
