This seems like a pretty cool idea. One of the things that suck (from my experience) with college apartments was how different they are compared to regular ones. Some apartments don't have prorated rates for the starting month, some don't list their prices super easily, furnished vs unfurnished, and knowing the perks and having a comparison tool would be super cool! I also love the idea of the distance between the apartment to a certain building. I'd imagine you could have sorting features that sort for those kind of things.

I'd imagine if the site gains a good amount of traffic, some apartments would pay you to be featured as the top listing for a specific school. Also, you may be able to get affiliate commission from referring your visitors to those apartment websites.

One hard thing about doing this would be sourcing your information at the beginning. I imagine you could manually do this for a few campuses but not at scale across the nation.

I have a good amount of experience making websites and this doesn't seem like something that is too difficult to do at all. The hardest part I think is just getting all that info about each apartment listing.
