[Account Closed]

Dears BP Members,

I was wondering to get one of these software, hope it can save my time doing analysis on "excel" and help to present the package to my Investor. But I need an insight from you all about the Excel "holly grail" of RE analysis
1. Have you ever paid for something like this ?
2. What's your typical budget for these type of projects ?
3. How high of priority is this for you ? 4. any more suggestion ?

These what i am watching :
