I think this is something that is highly variable - based on personal requirements, cost of living in your country and your acceptable minimum standards of comfort. I think techniques to minimise burn would be more interesting than actual rates.

One tip from my startup: I think a lot of people think getting employees and office space should happen at around the same time. I don't think office space is worth the premium you pay for it until you have more than a couple employees. We have one already and will probably only move after we have employed at least three more. Obviously a caveat here is that the house must be sufficiently pleasant for work and living and that your work is not something that requires client facing offices.
