I see this is an old thread, but I'll give a response if there are others out there interested in Wharton Real Estate VC. I'm a 2Y studying Finance and just finished our Real Estate Investments course (one of the two intro courses for the Real Estate major).
I agree with earlier posts that VC is hard to break into, especially coming from outside of PE/VC/IB. However, folks I've seen at M7 schools breaking into VC generally do so from a specific industry, and they'll get term-time internships. (E.g., I know a couple Wharton folks working term-time at VCs in healthcare and retail)
My thoughts for you, or someone in a similar boat is to think about what you want out of the program, what community is available for you there, and what you might do specifically to break into VC. Getting into VC from Booth, Wharton, Harvard will probably be similarly difficult, but how can you leverage your Real Estate background to break into a firm that's RE focused?
For Wharton in particular, there's a robust Real Estate community. Wharton arguably has the best Real Estate program, supported by the Zell/Lurie Real Estate Center. There are plenty of resources for career fairs, conferences, alumni networking, and financial modeling prep (through the Wharton RE club and access to Wall Street Prep) to support you.
I think in most top MBA programs, you'll also find great resources for financial prep, and VC-specific clubs. Wharton is no different in that regard.
Below are some resources I think could be helpful:
Wharton Zell/Lurie Real Estate Center
Wharton Real Estate Club
Wharton Real Estate Department (for courses and the concentration)
Wharton PE/VC Club
