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.
$50 capital will go no where with real estate investment same with a $1000-$5000 no matter what a guru you're into real estate development. There as specific amounts of money that are professionally recommended to start with as investment in the different sectors. You can't use an amount meant for a mini roadside grocery shop to invest in real estate and expect to make progress, not amount of hardwork put in can excel you. If wanna be fairly mean to such a person I'll say that investment is a dead one before it was started.
