My experiences, I did this three times and it worked out well for me each time. First, prices vary wildly based on builder markups, quality of products, size of suite etc etc.
Negotiate a take-back credit of appliances that they supply, you can upgrade the appliances on your own via Appliance Canada and do far better. If you have the means, always upgrade hardwood/carpet, tiles and cabinets to the best that you can afford. You'll get the enjoyment out of them and when (if) you sell, your suite shows better and you can command a higher price than comparative suites. Stay with neutral coloured tiles, cabinets and carpets, not everyone will like your decorating choices. If you definitely plan to settle there for a long time, go crazy.
