Rehab estimator help

[Aaron Maggard]

I'm trying to use the rehab estimating tool for the first time. It makes no sense to me. I'm getting negative numbers for builders labor and some numbers wouldn't purchase the item. Is there a video? I'm feeling stupid. I'm NOT new to this. I've been a builder for 3 decades. BP / Kukun has me stumped.

Stop using online tools, get contractors to walk your properties and bid the job.
