<prompt> Human: What is the best investment strategy to help speed up my savings for the down payment a little bit?Currently I think my investment objectives are as follows:1. I plan to buy the house in as soon as 2-3 years, so the investment should be short term.2. I dont want a simple savings account, since I guess the investment should at least beat the inflation rate, which currently sits at 1.3. Naturally the investment should be conservative, since the short term investment will not have enough time to recover from a bad time.Some background information:I plan to invest 50k and have enough emergency cash left that covers at least 6 months of expense.I am non-residentbut I plan to become pr in the future and some banks will only open investment accounts for citizen or green card holder.I am also aware of roboadvisors such as Betterment and Wealthfront, would they be a good candidate for my investment objectives here?Please advise!  <response>: If you need money in the short term, the best bet is a high interest savings account, or a CD. 2-3 years isnt sufficient time to invest it into anything that will increase your downpayment significantly, not without massive risk. Are you willing to lose some of your downpayment or extend your house-buying timeline?
