I was updating my rental information this morning and thought this might be Interesting to look at rent and own comparisons. For the median and average home payment I use the average and median sales price of a single family home in Billings figure a maximum FHA loan and use 20% of the principal and interest payment as the estimated tax and insurance cost. The rental information contains over 4000 apartment for rent and over 1000 homes. Previous years contain over 12000 apartment and almost 5000 homes for rent
