One of the best ways to get started investing in real estate is to buy a house in college and rent out the other rooms to roommates. One of my best friends did this – he bought a 4 bedroom house his freshman year and rented out 3 of the rooms. The rent from the roommates covered the rent and all the expenses, and he was able to pocket a small profit each month. By the time he graduated college, he had two rentals and a house for himself.
Barter your services with friends. Do you spend more than you'd like getting your hair and nails done each month? Do you have a friend who can't resist the pastries at the coffee shop or who pays for a personal trainer? Think about what both you and your friends spend money on, and then see if there's a way for you to barter and trade services with each other in order to save money.
Apply for new scholarships and grants. A lot of students think that they are only eligible for funding when they initially apply for admission. This is a mistake! There are often new scholarship opportunities for upperclassmen, though they aren't always widely advertised. You may also be able to apply for external scholarships or grants, which are offered from groups outside of your school.
