Pay Down Personal Debt or Next Investment?

[Justin Teal]

My girlfriend and I recently purchased our first home (I planned to house hack but honestly couldn't find a good multifamily in the area for our current price range due to time constraints of saving for our down payment) and are wondering if we should be paying down some debt before saving for our first rental property. She is in deferment so we aren't worried about that for the next 4 years, however, I've got about 30k of 4-5% interest rate student debt and 12k 5.2% car loan debt. Since those are lower interest rates we are considering just saving up for our next property (while keeping a safety net of course) instead of paying down debt. 

Thanks for any advise in advance!
