Advertising for a unit while remodeling?

[Mark Douglas]

I'm a few weeks from finishing a unit (almost a complete gut job, took longer than I'd planned!).  Should I just wait till it's completely finished to start advertising on Realtor, Zillow, etc?  I want to include photos with the ad, but I've seen some new construction apts going up that start taking applications before the building is completed.

Pros and cons?  Does the pool of applications seem better overall when there are photos?

Thanks !
