building a neighborhood up? and interesting hypothetical.

[Kevin Harrison]

 So this post a purely hypothetical but what is everyone's thoughts about building a block or small neighborhood, not new construction, but somewhere like Baltimore where homes can be bought for as little as 5-10K?

If someone were to get say 8-10 of these home in a condensed area, Rehab them to slightly above the local market, no million dollar homes but nice shrubs out front and mid-ranged interiors, do you think that that would bring the market of that street up above the surrounding area or that it would end up reverting back to the way it was before?
