These are mostly late 1950s-1960s homes. So you face some limitations .... generally small by today's standards, 8 foot ceilings, few garages, boxy and compartmental ranch-style floorplans. But they are well-built homes.
I flipped one here ... it needed a total rewire, re-roofing and some plumbing work. Houses of this age will have some things reaching the end of their lifespan so I didn't complain. Just be ready to sink several thousand dollars into "something" that a buyer's inspection didn't reveal.
At the crest of the housing bubble in 2006/2007, Monclaire was on the cusp of becoming the next "Madison Park" - a rediscovered area with homes nearing $300K. That's settled back a bit, and it's still something of an outlying area with value to be found.
Prices will always be supressed versus the neighobrhoods just north of it, because it feeds to Waddell High.
