Should I settle for 70% LTV?

[Thomas Fawcett]

Hey Guys, 

I have a duplex I purchased for $160,000 in a good part of Des Moines, IA (Beaverdale for the locals).  The Assessed value is $200K before we added an additional conforming bedroom on one side making it a 2-1 and a 3-1.  We put $20,000 into renovations bringing my total purchase and rehab cost to $180K.  Monthly rental income is $2,100.   

Our goal is to hold this property so we are looking for a 30 year fixed loan.  We purchased the property in June so December will be our 6th month mark.  credit score is high, I have a good paying W2 income, and no other debt.  The lender I am talking to quoted me 6% and only 70% LTV.  Should I shop around for better rates?  

This is our first property so any advise would be awesome.  If you are local, do you have a recommendations on a lender?  Thanks!
