There are 30 Claridge townhomes from the mid-90s on Forward Ave and Lyndale in Mechanicsville, and there are even nicer ones a block south, but the Soho Parkway will block out the sky from their backyards.
The Lebreton Flats townhouses are a little older, but fairly nice and tend to go in the 360s-380s.
These places here are right by Hampton Park and the listings I've seen tend to be more reasonably priced (always in need of updating though)

There are some smaller townhouse infills scattered around Carlington too, which are a bit more affordable, and could be desirable as Carling and Merrivale North slowly improve... over the next century! ;-)
Good luck; townhouses in the urban area at entry-level price points are crazy competitive (don't be surprised to see a dozen other bidders driving prices to 10% over asking)
