This seems to be the cheapest accredited option, use University of the People to get any kind of undergrad, then can pay for a masters in CS somewhere else. (Too bad uopen doesn't have an applied math undergrad, then the material being dated wouldn't matter).

There is Athabasca U in Canada which offers a fully online, and accredited BSc in CompSci or Applied Mathematics, and the only requirements are 16+yrs old (no transcripts or even highschool grad needed) but the fees are $900CAD or so for 3 credit courses and you need to complete 120 credits so ~$35k for an undergrad ($27k USD). http://www.athabascau.ca/programs-courses/ whereas you could do Upeople, obtain an undergrad and pay for Johns Hopkins MSc for the same cost.

There's also been reports that Athabasca U is having funding issues at present, for those looking at this option (which is the only option in Canada for online in this field that I've found.)
