Can you please check these sentences for me? Thank you.

1) If I won 2 million Euros at the lottery, I would transfer part of the money on(to) my bank account and invest it (in state bonds/government securities)
2)I would buy myself a house in the mountains and one at the seaside. I would also have a swimming pool built in my garden.
3) I would enter rally (?) competitions (Formula-1 competitions)
and donate part of the money to charities. I would certainly save some money for bad times (for old age?).
