Right now you can generate a report on the property using as little as Address, Purchase price, Square footage and a guess of beds/baths. We estimate the rest based on market data - the basis for each estimate is shown in the report.
I run SimplyRETS[0] - we provide a normalized API to MLS's RETS data. I'm not trying to sell you anything, but I'd love to team up - You should shoot me an email (cody@simplyrets.com)!
Best of luck and great work on the product!
