Just to clarify about the house allowance:
For married is Bd350, plus utility allowance of Bd48 (if it is a fully furnished flat), plus 10% of the flat's rental (for the taxes). Nowadays it's quite hard to find a decent flat for Bd450, I took almost one year to find one, during this time I had to pay additional Bd200 from my pocket for a flat.
You will never find a villa for less than Bd650 and 99% of them are not furnished, in this case you'll have to buy the furniture, pay the taxes, internet (about Bd40 for a 512!), satellite TV, etc.
Put it in a piece of paper and you will spend about Bd800 just for a place to live!
