Nr. 1 Back up money, Set an amount of lets say $1000 to have on a bank account for rainy days.

Nr 2. Go to you local bank or find a fund broker online that accept monthly deposits. Set an amount you can save each month. Ask for advice from someone trustworthy. I know Norwegian based funds, but not where you are from. This is supposed to be long time investment and should normally give you 6-10% return each year.

Nr 3. When you have enough money, buy a flat with one more bedroom then you need and start an AirBnb business.

Nr 4. Buy houses for letting out. Always ask for advice from people who have made it before you and that you can trust. If not you have to learn everything you need before you start, You don't want to learn it the hard way.
