Im a homeowner a mortgage guy and a CPA. This rocks. Stop looking now load it and love it. I highly recommend this for more sophisticated homeowners /Homebuyers, real estate agents; definitely for mortgage professionals. this is without doubt the best financial calculator for a mortgage that I found in the App Store and I mustve tried least 10 others. this is got great features its very simple to use and I like the fact that this can scale up from simple to advanced and that its designed to be easy. I can see qualifying ratios and qualify people over the phone in real time wherever I am and then email it to myself and to them. And one more thing… Did I mention that you can save your scenarios? very cool. The only glitch I have found with this is due to third-party keyboards. I use swype but I found if I change to the regular Apple keyboard that I dont have any problemsat all.well done! kudos!!
