$250 - $750

Project Description:
I need a plug-in database operational from my admin control panel of a website to forecast real estate sales data. see attached document for full details but here are the basics below:

I want to use the difference of the first time sell price to the second time sell price (positive and/or negative) the hold period, related expenses, rising and/or falling viewer interest… to build forecast models for a given individual condo unit (micro) and/or a given building containing many in ividual units (macro)?
Simple fields that plug in the buy vs. sell price – hold periods expressed in months and/or years – expenses in USD – interested viewers (from 1st sale to 2nd sale expressed in numbers – say 1-10,000), and additionally a simple “return of investment” ROI calculation output that displays the simple annual interest (as a negative or positive value) of the particular calculation being performed. The program should display forecasting data for an individual and/or total averaged data for many condo units within a given building.
I would like the program to hold and retain the data on many thousands of individual condo units which can and stored according the name given to the individual building name the individual condo units reside in.
I would like this software to be proprietary to me and if this is a non-start please let me know.
Lastly - this real estate sales/viewer interest forecaster needs to be able to be accessible from the admin control panel of a website I am creating and also be available to my website users that I grant a special access code and/or username password (separate from the log in username password access point on the register page…).
If you need additional info please let me know – google Case Shiller real estate forecasting models for more inspiration – Thanks
