Saving/ Investing a lump sum
In my mind, when looking at a five year period you have a number of options. You didn't specify where you are based, which admittedly makes it harder, to give you good advice. If you are looking for an investment that can achieve large gains, equities are impossible to ignore. By investing in an index fund or other diverse asset forms (such as mutual funds), your risk is relatively minimal. However there has historically been five year periods where you would lose/flatline your money. If this was to be the case you would likely be better off waiting more than five years to buy a house, which would be frustrating. When markets rebound, they often do it hard. If you are in a major economy, taking something like the top 100 of your stock market is a safe bet, although admittedly you would have made terrible returns if you invested in the Polish markets. While they often achieve lower returns than equity investments, they are generally considered safer - especially government issued bonds. If you were willing to sacrifice returns for safety, you must always consider them.  This is an interesting new addition, and I can't comment on the state of it in the United States, however in Europe we have a number of platforms which do this. In the UK, for example you can achieve ~7.3% returns YoY using sites like Funding Circle. If you invest in a diverse range of businesses, you have minimal risk from and individual company not paying. Elsewhere in Europe (although not appropriate for me as everything I do is denominated in Sterling), you can secure 12% in places like Georgia, Poland, and Estonia. This is a very good rate and the platforms seem reputable, and 'guarantee' their loans. However unlike funding circle, they are for consumer loans. The risk profile in my mind is similar to that of equities, but it is hard to say. Whatever you do, you need to do your homework, and ensure that you can handle the level of risk offered by the investments you make. I haven't included things like Savings accounts in here, as the rates aren't worth bothering with.
