At the risk of being off topic, have you considered non direct financial investments?
Physical investments, like the comment about the leaf blower and rake, require time but produce a semi-stable option if you are willing to accept the full scope of what you're doing.
I personally have invested in various pieces of equipment that allow me to generate a relatively healthy passive income that easily meets and far exceeds the goals you have outlined here. Obviously I won't disclose what they are because I don't want to create competition for myself, but the basic idea is enabling yourself to provide a good or service that other people would gladly pay you for.
Not all of this has to be intensely time consuming or costly. If you have $1100, and you were willing to risk $500, plus invest some time setting things up, you could easily generate a few hundred a week off of simple nightly tasks like pushing a few buttons, stuffing a few envelopes, and stashing away all the funds so you can adequately and accurately calculate and pay the necessary taxes on the venture. In the US, that's whatever your tax bracket is, plus the self employment tax.
This answer is meaningless without some kind of guidance, so here's the nutshell that is not what I am doing, but I have proved this concept for others who thus far have never taken on the challenge.
I can sew. Goody, right? I also have kids. I found that I needed some things for the kids when they were babies that were either not commercially available, or they were absurd in price, or bland in design. So I made them myself. I made many. I gave them out at baby showers and people loved them. I sold them on ebay for a while and they sold without flaw. Little baby blankets, pillow covers, crib liners, etc. Each one taking some 15 minutes to make, cost about $7 to produce, sell for $30. All said, $15 profit on each item. Taxes slaughter that number down to about $10. 20 units a week I didn't need. Set it aside and invest in the next thing to waste my time with and eventually retire the more complicated things.
You may not sew, but the example is still valid. You can invest your funds into a passive hobby based on observed needs or trends. I did this exact one myself and it made money, but I don't feel like sewing pillow covers and blankets. I moved to other products and most of them now require almost no attention and costs are down to pennies per unit. Some cost zero and are just pure profit.
I put all this money aside and put a down payment on a house, same as your goal. It may not be the investing you were looking for, or what this site is trying to help people with, but it is what I did and it worked for me. It is still working for me now.
