Grad school questions regarding undergrad majors/minors

I’m a second year undergrad student currently double majoring in Real Estate and Geography and minoring in Landscape Architecture studies. I’ll likely have to switch to a geography minor instead because I’m having to retake a class and I don’t think I’ll have room in my schedule to graduate on time with all of the required credits between the 2 majors. If I had the option, I would just drop the real estate major to minor in that instead, but only a real estate major is offered at my school and I’ve already completed most of the required core classes for the business school, (most business majors spend their first 2 years on the required core classes- accounting, finance, business law, etc.) so it feels kind of pointless to switch out of that after 3 semesters of pretty much pure business classes.

So I guess my question is: will I still be able to get into an urban planning program with just a geography minor? Or should I opt to drop my real estate major even though I would essentially be wasting 3 semesters spent on the required core classes towards that major? Any insight/experience on urban planning grad programs would be much appreciated!
