What is your strategy for selecting a lender?

[Rumi Velazquez]

I am working on my first deal in St. Louis and seeking guidance on how to best select a lender for my first investment property.  I have ~$20K for down payment and thinking I can purchase a property between $100K-$150K using conventional loan, with 10%-20% down.  First off, is that realistic?  I own my current residence so have that on my credit report. My initial strategy is to buy and hold.  Should I use aggregators like better.com or lending tree on BP to compare quotes, or ask around for referrals?  Thanks in advance for any input you can provide.
