RE newbie ready to make my first purchase. Advice ?

[Kristina Concord]

Hello All,

I'm interested in buying my first place in Boise Idaho.  I believe I would like to find a duplex to purchase and either rent out one side to a long term tenant or do a AirBNB vacation rental type.  I don't think I will be able to find anything larger then a duplex, because I was only approved for $250k and have $30k down. Is a duplex the best first step for RE Investing? 

Thank you in advance!
