Actually, both 5 and 35 Mariner Terrace are quite nice. Something to know about a lot of the Concord developments, is that there are two active lawsuits at the Matrix (361-373 Front) and Optima (81 Navy Wharf). Both buildings will require 20% down, because CMHC will not insure until the lawsuits are resolved, which have been active for more than 6 years. As much as I think Mariner Terrace is a nice building, I would suggest to get a status certificate first to understand what is going in terms of repairs, reserve fund, and builder issues first. Concord and Tarion are both named in the lawsuits, and neither of them have taken responsibility for the building issues that have taken place. Not saying that Mariner Terrace will have the same issues, but if something is discovered, and Concord needs to take action, they seem like they won't. A building that only allows 20% down will lower your resale value. Already seeing that at the two buildings I mentioned above. Good luck.
