What do I need to do to PREP for RE-TEXTURING of indoor walls?

[Zach Schwarzmiller]

Finally took back my unit through the abandonment process! Now my walls are nice and messed up and I need to get someone in there to re-texture. I found a handyman on Craigslist I am going to meet with tonight and see how he seems. Said he's done tons of this and sounds pretty knowledgeable.

Anyways, he asked me if the walls had already been prepped and I didn't want to ask him what needs to be done as I want to sound knowledgeable when I meet him so he doesn't think I don't know anything (which I really don't) and take advantage of me on pricing.

AH! Another good question: What is a fair price to pay for a re-texturing of walls in a 3 Bed 2.5 Bath 1,250SF unit?

Anyways, what do I need to do in order to be "Prepared" for the Re-Texturing of these walls? I am hoping to have him start tomorrow afternoon so perhaps I need to devote my entire evening to this.

Any advise would be GREATLY appreciated. I am a numbers guy, I have a lot to learn about physical maintenance of property! IRR, NPV, DCF, got it... How to prep a dang wall -- Could use some advise. :)

THANK YOU!
