Frequently Asked Questions

Can software really replace consultants?

For routine acquisition DD, yes. Software like DDee.ai delivers comprehensive analysis faster and cheaper. Complex advisory situations may still benefit from consultants.

How do I justify the switch internally?

Show the math: cost savings, time savings, tenant credit capability, capacity increase.
