Creating a Form that Posts to a Blog

I'm making a WordPress for somebody, and they would like to have a form that will contain information pertaining to realty. They would like to be able to go to a page on the WordPress, access the form, and have the form output the information to the Posts.

I've created a form with Ninja Forms that has 13 or so input boxes. How can I have WordPress post the content of this form into a Post while retaining the format?
Ex. "Business Name: _______" to Business Name Bernard's Bistro
"Listing Type _____" to Listing Type Commercial
"Number of Bedrooms _______" to Number of Bedrooms 2
etc?
Any help would be appreciated :). Thank you!
