Medium-term money investment in Germany
Due to the zero percent interest rate on the Euro right now you won't find any investment giving you 5% which isn't equivalent to gambling.  One of the few investment forms which still promises gains without unreasonable risks right now seems to be real estate, because real estate prices in German urban areas (not so in rural areas!) are growing a lot recently. One reason for that is in fact the low interest rate, because it makes it very cheap right now to take a loan and buy a home. This increased demand is driving up the prices. Note that you don't need to buy a property yourself to invest in real estate (20k in one of the larger cities of Germany will get you... maybe a cardboard box below a bridge?). You can invest your money in a real estate fund ("Immobilienfond"). You then don't own a specific property, you own a tiny fraction of a whole bunch of different properties. This spreads out the risk and allows you to invest exactly as much money as you want. However, most real estate funds do not allow you to sell in the first two years and require that you announce your sale one year in advance, so it's not a very liquid asset.  Also, it is still a risky investment. Raising real estate prices might hint to a bubble which might burst eventually. Financial analysts have different opinions about this. But fact is, when the European Central Bank starts to take interest again, then the demand for real estate property will drop and so will the prices. When you are not sure what to do, ask your bank for investment advise. German banks are usually trustworthy in this regard.
