Community college worked well for me. 2 weeks after graduating high school I started taking a heavy workload at the local community college. I was able to complete the prerequisites by the following year and transfer to a local state university. I was lucky that both were within a 45min drive from my house.
The result was graduating college with a bachelor's degree 2.5 years after graduating high school. I lived at home for the the duration (rent free as long as I maintained a 3.5 GPA) so the full cost was only around $6,000.
This was in northern California (Modesto Junior College and Cal State Stanislaus) with a relatively low cost of living. I know the costs have increased since then (I went in the mid 2000's), but I assume it's still relatively affordable.
