With less than 2500 USD you won't be able to make any direct real estate investment. This is something where you need a lot of money and still likely need to use a loan to property. The only alternative for you would be to buy into an investment fund that buys properties and rents them out. The problem here is that you have to pay all the fund fees and can't freely choose which property to invest in. Then again with 2500 USD I am not sure if it makes sense to buy into these funds, because you might have to pay 5% fees for purchase and sell. Don't get me wrong, real estate is a great investment for any portfolio, it gives a diversification benefits and good period income. Just make sure you have enough capital and don't pay too much in fees. With 2500 USD I would recommend to go for cryptos and wait until you have more money for real estate investments.
