I understand the point, but I think it is misapplied with the front range. Housing cost increases are outpacing median incomes by a large margin. The prices are so high in the front range that this advise falls short. For those of us already here, yes, selling and moving is great advice. If you are thinking of moving now, I think you’ve missed the boat. I say that for anyone who might be considering the move.
The only place on the front range with discretionary income worth mentioning is in Boulder, CO. If you can afford the price of entry in Boulder AND you have the education to find a high paying job, then you might do OK. I just don’t think the average Joe is going to be able to get started on an average $1800/month for a single bedroom apartment or to purchase the median home in Boulder for $899k.
