Any recommendations for good investor friendly agents I can shop the rate with? 

Hey John, As others noted, you might want to shop a few local CUs to finance this with a HELOC.

.- Shop around for lenders that specialize in owner-occupied multifamily properties.- Use tools like the BiggerPockets mortgage calculators to see how different interest rates and loan terms affect your cash flow.If you have more questions or need further guidance, feel free to ask Good luck with your duplex venture

You are looking to create the biggest spread possible so shopping around for the best rate and terms should be a priority.

@Megan Paquet NelsonA good remindee why investors really need to stop price shopping on insurance and really shop based on coverage, a great agent, and actually read their policies so they know what their coverage is and isnt.

You chose a property manager without shopping around and comparing multiple professionals in the market.

This will narrow your shopping area then you can hunt for the deals. 

As realtor/investor who specializes in working with investors, I can be your one-stop shop here connecting you with home inspectors, general contractors, and property managers all of whom I know and trust.

Most enticing is it is located on a very well established street with a wall score of 92 - lots of restaurants, bars, shops and a park nearby.

Im wondering if it would be better for me to wait until I have the money in my bank account for a down payment, or at least another paycheck in the account (paid monthly) before I start shopping around for pre-approval letters.
