Good First Investment? Looking for opinions/advise

[Tj Hulse]

I'm 24 years old and recently purchased a Townhome in the Robinson area (Imperial). Mortgage is $600/month and two roommates are paying me $450 a piece for $900 monthly "income". We are splitting all utilities 3 ways though they are in my name. Conventional loan 20% down - $150K purchase price. Doesn't meet this 2% rule so just looking for advice/opinions. Worried I overpaid on first home though I am "hacking".
