"The guy" your realtor uses represents a conflict of interest. That means this guy's priority is getting in and out and finishing the job quickly. Not necessarily at the lowest cost, not necessarily the best job, but nothing so terrible that it would hold up a sale. know that up front. And the realtor uses him because he's cheap, more profit for him when he flips. That doesn't mean he will come cheap to you. But that explains why it's not an all inclusive service. As mentioned above, you may find other annoying aspects of the job, which the contractor doesn't have to be concerned about on flips, because nobody lives in the house - like cleaning up after himself daily because you have live and eat in that construction zone.
The dumpster is the MO the realtor uses for larger jobs, contractor doesn't need to be concerned with it, he just shows up with his tools and materials and gets to work. If your job is pretty large, go with the dumpster. If you have time and it's a smaller job, there are other options, but you'll have to get your hands dirty. Waste Management sells those green "dumpsters" that will hold a few cubic yards of debris. When it's full, just call them and they cart it away. I think they are less than $50. Many towns will accept bulk trash, but they will have strict rules you have to follow (bagged, no nails, limits on # of bags or weight). I've dropped off doors, toilets and other misc construction debris at my township recycling center, but these were smaller jobs where 1-2 trips were needed. I wouldn't want to be driving back and forth all day. The messy stuff I didn't want in my car I would bag and put in the weekly trash a little at a time. But these are small contained jobs where a dumpster would be a waste (no pun intended).
