Great Question and I am glad you asked it. I am sure you aware of the buildings that already exist in the pearl that are available for incomes such as those stated. For example, the Lovejoy Station at NW Lovejoy and 10th is a building that subsidizes rents based on median incomes, so do several others including one for ages 55 and older. The district also has a number of apartment buildings such as the Wyatt, The Burlington, The Louisa, and soon to come The Lovejoy all of which offer market rent apartments to the general public.
As far as foreclosures, the district does have a number of them available and on the market. The best website to use for foreclosures in my opinion is http://www.usa-foreclosure.com
or with your preferred Realtor.
I am biased when it comes to the Pearl as it is the primary neighborhood that I work in, but I feel that it has been planned very well for a new neighborhood and will continue to adjust as time progresses. It is a highly competitive district when it comes to housing, food, entertainment and quality of life. There is plenty of on and off street parking, housing opportunities for all income brackets, Fine Arts, Galleries, transportation (including the infamous ZIP car http://www.zipcar.com
) and educational institutions etc...
Hope that begins to help you with your question.
Best of Luck,
