Refinancing Fourplex Property- Beginner Here!

[Rick L.]

I purchased my first multifamily fourplex in June 2012. I paid 3.5% via a FHA loan @ 3.67%. The approximately $400/month in PMI is killing me so I've decided to try and refinance the property. I'm hoping for a favorable appraisal so I refinance to a conventional loan with 20% equity though a higher appriasal value.

I have performed several updates including installing a new roof, new aluminum gutters, updating one of the units (kitchen & 1.5baths), french drain system, new paint throughout, etc, etc

Do you have any recommendations for a Noob to the refinance process?
