You have already computed your birth chart with full details. You know what Dasa is going on and what anthardasa is going on. If you can do all these, you could easily find the effects of that too. Do you want us to verify whether your computations are correct or not?

I think you are mis-associating Rahu with all your problems. Your Rahu is quite powerful in your horoscope. But Mars and Moon are malefics and it is their influences which could be giving you the problem which can happen anytime since all the planets work in tandem always in one’s life. You read my articles on http://navagrahastro.blogspot.in/ to understand the concept of Dasas and antardasas.

Your 4th and 5th houses are particularly weak in the horoscopes as given below and these could be the ones which are giving you tension and discomforting finances.
