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

I had one particular vendor with high standards that would exaggerate anything he found.My rule of thumb: people can live how they want to live as long as they are not 1. damaging the property2. living in filth that attracts pests3. impacting the neighbors (e.g. odors, junk detracting from the neighborhood, etc)4. creating an unsafe situation (e.g. hoarding and rescue workers can't access the home)When I visit a property, I document any issues and talk to the tenant.

At first glance it seems like decent neighborhood but any insights and experience would be super helpful?

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

How clean and safe is the neighborhood?

.- 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

-We have had our condo in Oceanside for almost 2 years now and the value according to Redfin and some comps in the neighborhood have increased the value of the condo by at least $80,000 ( rough assessment ). 

Can try to reposition to Class B, but neighborhood may impede these efforts.Vacancy Est: Historically 10%, but 15-20% should be used to also cover tenant nonpayment, eviction costs & damages.Tenant Pool: majority will have FICO scores of 560-620 (approaching 22% probability of default), many blemishes, but should have no evictions in last 2 years.

Also, I would recommend using an agent to provide you with handpicked comps that are similar to this property in this neighborhood to justify the value.
