Pay down my loan or save for the next investment?

[Jeff Dimmler]

I recently purchased my first home!  Currently, I am living the townhouse I bought and plan on renting it out.  I would like to either purchase an investment property and keep living in the current place, or house hack the next place and rent out the current.  If I decide to go with option one I will need to save up a bit more and find a place with tenants to qualify.  I am also renting out a room to a friend, so I have a bit of house hacking going on here.  Anyways, now that you know a little bit about my situation, should I save up more now or spend a little more per month towards my principle?  I have about $300-$450 per month to either save or pay the principle.

By the way, I could not have done my first deal without all of the great people here on BP!  Thank you so much to everyone who has answered my questions!  There is a lot of great content on here!
