You're talking about a $50 investment and you're talking about real estate? As crazy as it sounds, no investment will generate much profit with $50 of capital. You need more money, I think if you don't have money to invest, it's better to focus on increasing your monthly income, if you have enough money left for living needs, then think about investing.
It is important to search a lot of information before investing which you need to understand and keep in mind were invest what you can afford to lose. I agree with you that it's better to focus on increasing first your monthly income aside from that is you have to divide your earnings which is you need to separate first your base or your savings, and it's up to you if you will re-invest half of your money, but you have to consider the risk that it may not all be a good outcome for you.
