I did my undergrad in business administration, but did not touch on real estate. I have 30 days to get excel modeling proficient for an acquisitions role focusing on the main re sectors [office, retail and multifamily rental with possibility for hotel].
What books should I read, and what classes and models can I study to become proficient? I am literally on a shoestring budget of $100 so any free resources to bootstrap my learning would be extremely appreciated. I am feeling tad desperate and am planning to hit this for 16 hours a day if need be.
