Hello again wil45 (hope you're not getting sick of me replying to your posts). If you're truly an "Urban Pioneer", I think the Cleveland neighborhood might disappoint you - a lot of middle-class families living on quiet tree-lined streets adjacent to the parkway, so it might not be as exciting as you'd like

. But if you're saying that you would like to live in a neighborhood with both ethnic and socioeconomic diversity, then Cleveland is a good neighborhood to live in- according to that 2000 data it might just be one of the most integrated neighborhoods in the state and/or region (almost equally white and non-white population which I doubt has changed a whole lot). But even with this high level of integration, I would bet to say that the neighborhood itself is probably a little segregrated with a lot more of the white folk on the north and west end of the neighborhood and a lot more non-white persons on the east and south ends.
That 2000 data puts cleveland at having the second highest median household income of the north neighborhoods next to victory (due in part to adjacency to parkway I'm sure), and unless the pricey new townhomes that were built in shingle creek and willard neighborhoods in recent years has made a big impact I would think that cleveland is still one of the higher income earning neighborhoods of the north neighborhoods.
Cleveland neighborhood starts on the block just south of mine so we go for walks through the north part of it a lot. Nice homes and families, like Victory it seems like there are a lot of homes being rehabbed by youngish buyers and a fair number of GLBT homeowners (and sorry for stereotyping, but I've always thought that a large gay homeowner population was a strong indicator of a great neighborhood on the upswing).
Like the rest of the cities, the market has come down quite a bit around here in the past couple of years - a couple of years ago a small bungalow w/ one bath would generally sell for over $200K (in Victory especially and sometimes much more than this)...and still today, depending on the condition of the home and its location in regards to park spaces/ amenities you might still find this same style/ size of house selling for between $180 - $250K; but most likely (unless it's on xerxes, washburn, and maybe Vincent) it will likely sell for $140 - $180K and sometimes higher/ lower depending on condition.
I don't think there's a lot to worry about in Cleveland, when we were looking we were seriously considering some houses just north of Lowry Ave (3200 - 3400 blocks - very southern end of cleveland) as homes were more affordable there, but I am very glad we waited for something in a better location to come up as Lowry Ave west of Penn can be a pretty busy street, and it can be pretty active at night with a restaurant/ bar (great one though - Tootie's on Lowry) and a busy gas station right there. Plus all the ambulance traffic that travels Lowry due to it being a main thoroughfare to North Memorial a couple blocks down.
Although technically I live in the first block north of the Cleveland neighborhood, let me know if you think there might be more questions I could answer for you wil (or if you want me to do a drive- or walk-by of a house for you - haha).
