In need of some advice

[Christopher Nathaniel Hart]

So I just purchased my very first house, which is also my current residence for my wife, two children and myself,  I had to completely drains my savings in the process.  I know I'm at least 1-2 years out from being able to purchase my first rental property because i have absolutely no capital saved.  My question is, would i be better off dumping all my extra cash into the principle of my house to build equity that i can later use to help purchase my first investment or would i be better off putting my money into a savings account ?
