short term questions with home purchase

[rt1]

ok, so i invest a lot, but all my investments are long term things (10+ years). say i wanted to make a large purchase in the next 12 months (like a house).

Where is the best place to keep and save money for this? I am guessing a CD or one of those 5% savings accounts?

How much money do I put in that short term account? I want to get a mortgage so I can leverage my existing money in the market. I will not be paying for the entire home upfront.



sorry if this is really stupid, i am just clueless when it comes to short term investments.
