Builder buy a old home , rebuild it with two semi, so they can make some money. You get want you pay for. A new house but smaller lot. The location usually is good.
depend on your situation, it may be more easy for you to live in that home than a single likely in kanata or other place far from city core.
For investment point of view, smaller lot price rise slower than bigger lot in the same area. But for different area it may not be the case.
