I've got a couple of potential real estate web design inquiries and need a long term solution for a few items that are likely out there already. I've been doing the seo for real estate and related sites, the design for myriad other types but have never done a straight re site from scratch.

To start with... I need an easy to use/integrate mortgage calculator script. The cheaper the better, and as flexible a licensing as possible. I've looked at a couple of script repositories and there are alot of options. I didn't know if you had any recommendations. I'd prefer to hear from those using similar to reply more so than those writing/promoting them.

What are you guys/gals using?

Any other recommendations on essential functions (just the code) of a good real estate agents site are welcome.
