Mortgage Calculator Tools

Through my research for my project I found various tools for those who may be interesting in buying a home.

Private Mortgage Insurance (PMI) Calculator

This tool estimates how much your PMI will be if you don't have the ability to put 20% down on your mortgage. From there, you'll be able to decide if it make sense to try to do an 80-10-10 loan vs. pay the private mortgage insurance. Note, there are tax implications that may make it more economical to avoid the PMI. I know that congress was looking in 2008 to also make PMI tax deductible.

Neat Mortgage Calculator that Graphically shows you the amount of principal and interest you would pay.

It's really eye opening to see how a few extra payments really reduce your duration. I wish we would have found this earlier because we did all these calculations manually in our project!
