I don't live in Pueblo, but I love to invest there. Some others have talked about cost-of-living that is likely to continue to draw new residents and businesses over the long-term. There is plenty of sunshine, mountains, the lake and the riverwalk for recreation. There are educational institutions like CSU- Pueblo and Pueblo Community College. There are hospitals and a still a fair bit of manufacturing that is going on in the area of the steel mills.
People also talk about the decline of the steel mills, but the worst of those lay-offs happened in early 1980's. I heard something like 5,000 jobs were lost in that period. And yet the population of Pueblo city and Pueblo county have continued to grow. I'm from Ohio, where many of the industrial towns didn't survive the industrial lay-offs and now populations are half or a quarter of what they used to be. That didn't happen in Pueblo and I don't see it happening in future.
I appreciate @Robert Herrera and @Rick Thomas giving some local insight into the local market. I often get tired of people from northern Colorado speaking ill of Pueblo with little knowledge of the local market. When the next bubble pops, I would much rather be invested in Pueblo than Denver.
