The rent-to-mortgage payment ratio uses the adjusted rent for Birmingham against a 100% loan-to-value mortgage (30-year fixed) for the median price home using Realtor home sales statistics. It's a lot like a cap rate, but I find it more appealing in ratio form. A ratio of 1.0 means that annual rent is equivalent annual mortgage payments. Values less than 1.0 indicate rents are cheaper and values greater than 1.0 mean mortgage payments are cheaper. Beware, taxes are not considered here.
