Mark, your RIGHT choice
It is unlikely for you to find such a unit currently, as stack 25 has been fully sold. The purchasers for this stacks bought the property sometime in 2017/2018. Hence, they will be subjected to fulfill either 3 or 4 years of SSD. If they were to sell the property to you now, they will incur hefty SSD.
Unless the owner met with serious financial difficulty, it is unlikely that you will be able to get such a unit at your desired price.
Are your looking for a bigger unit for your own occupancy in this development? Are you open to consider other options?
