While many brokers will advise Stapleton and there is continued growth and opportunity, I believe there are neighborhoods to the east and south of Lowry (located in Aurora and Denver) which offer many opportunities for underlying equity appreciation and demand over the next 3-5 years.
Concerning pin-pointing neighborhoods, there are consideration from housing stock desired to school districts the differences in taxes and services offered by Denver and Aurora which need to be factored in.
Also, while I agree Stapleton has been and continues to be successful, I have personally had clients who work in central and SE Denver as well at DTC who did not consider Stapleton due to the commuting challenges and concern about continued development within the boundaries versus more established and land-scarce neighborhoods closer to Lowry.
Yet if you are desiring new construction, Stapleton is an excellent option with price-points from starter to luxury. However if you would consider a fixer-upper or have some flexibility on house-size, age and lot, there are many excellent options. Personally I have been looking at neighborhoods east of Quebec from Lowry to DTC. Some excellent opportunities including neighborhoods with parks as well as east access to arterials/highways and strong schools in both Denver and Cherry Creek Districts.
