Real Estate Calculators

I spent some time writing some real estate calculators. If anyone needs a calculator for their site I am offering them free for use by other webmasters. I designed the page to be generic so it could fit into other peoples sites. There are two options. The first option should work on all browsers. The second option is a little fancier so it might not work in older browsers but it hides the address bar so users cannot see they have left your domain. Anyway have fun. I am probably going to write some more so feel free to send requests for additional calculators.
