<human>: How should I be investing savings to prepare for a down payment on a house? I currently rent an apartment but would like to buy in the next 2-3 years.

* Age: 24
* Income: 50 K
* Savings account: 11K in high yield savings account (2.8%)
* Stocks: 3K
* 401k: 6 K
* Debt: 0

After expenses, excluding 13% contribution to 401K, I place about $700/month into a high yield savings account. 

Research tells me I should maintain a cushion of 2-3K in cash and move all remaining savings to a low risk mutual fund (likely above 3%/year returns) until the money is needed for the down payment on a home. Does this sound right?

Give me the gist of the text in a nutshell
