Hi- Symes has a decent name, and they have been around a long time. They do a lot of commercial / office properties and some retail as well. They have also done some townhouses and condos, etc.
They have built a lot of properties over the past 20 years. Any developer like that will have a bunch of nightmare stories/ bad results. That is a given- it is a numbers game. But, do the good stories outweigh the bad? My guess is - Yes- you just don't hear about the people that are satisfied.
It's also about perception vs. reality. Many people who buy a new condo think that they will never have to worry about anything ever again. That is not the case, and the homeowners themselves still have some maintenance requirements, etc.
If I can be of any help, please let me know. Thanks, and good luck,
