Thanks again for all the feedback
Fundamentally you want to be telling a Story. You can make it fairly simple. People use your product, get a simple form that they can use, and get an apartment. Your form doesn't look simple to fill out or easy to read as a small image though.
Frankly, if I was going to do it, I'd make it very simple. Start with an image or animation representing all the applications that landlords look through, with something like, "lost in an ocean of applications?" replace ocean with pile, or show a stuffed mailbox, or e-mail box.
Then show your form causing the individual to stand out.
Then show the handshake, or moving in, or signing the lease.
I think that story works for both applicants and landlords.
And if you want to display the actual form, make it a diagram, with pointers to each of the parts. That might be a better thing to display then the image of the building, which doesn't convey much to me.
Maybe a picture of a building, followed by a handshake followed by keys in hand? To tell the story without words? But don't remind me of the paperwork. Find a way to tell me you are the person who will spare me the pain of the paperwork, because I don't fucking want to do the paperwork. That's what I presumably am paying you for. So show me imagery of how easy and painless this is, not imagery of torturous paperwork.
Just my opinion.
Best of luck.
