That is a different question from your first one posted. The builder is doing a 3-2-1 buydown. at the end of the third year the payments will go up.to at least two points. In today's market it is a very good idea to get a long term fixed rate mortgage. Work with your builder for a price break if possible to help. If not you may be looking at a little to much house right now. Remember that your taxes will increase in the second year of ownership.
