Not a good idea to house snakes together . Housing them together raises possible risks that would never come into play if they are housed separately. You could potentially house two snakes together and never have an issue but you could also house two snakes together and one or both could get sick, health issues or even die as a result. A result that could easily be avoided by just buying two enclosures. If you can't afford or have the space for two enclosures just don't be selfish and only buy one snake until you are capable of responsibly have both.
