Should I take advantage of loans to jumpstart investing?

[Jessica Gonzalez]

Hello everyone, 

I am an aspiring real estate investor in the San Antonio area. My husband is in medical school and I just finished my masters in engineering. Luckly, I graduated debt free and so did he for his undergrad (he is currently taking out loans to pay for med school). Both of our cars are paid off so we do not have any debt to our names other than his med school debt. I will begin working very soon and we will be able to reduce the amount of loan $$ we have been borrowing. My question is, should we take advantage of the loan money and use it to pay of our monthly rent to help me save up as much as I can, or should we just upfront use the loan money directly to invest in real estate? Or should we just keep it safe and not take out extra loan money and slowly try to save up $$ from my engineering salary? BTW, loan interest rate is fixed at 5.28%
