I'm starting to save up for a down payment on a house. My track would put me on 5 years to buy one, just by putting the money into a saving account.
However since the money will be sitting around deteriorating I want to start investing it in something so it'll generate some extra income for me. I have 2,500 dollars saved up right now. I plan to put away $400 a month away until 2015, then increase that per month saving by at least $100 every subsequent year (2015: 500/mo, 2016: 600/mo). With this I'll have $4,500 at the end of this year, $26,00 by 2018, and in 5 years I'll have $41,000.
Any advice on how/when/what I should invest this so that I can take it out with relative ease in 5 years, and have made some interest the whole time?
