Refinancing a property I bought in September?

[Alex Gaeta]

Hello was hoping someone might be able to help me? I purchased a home in September with a doctors loan with zero down for 329k. I was notified via redfin that my property value is 339k. I'm installing some hurricaine windows so I imagine this increases the value? Anyway my interest is 4.12% and I still owe 324k on the property. Does it make sense to refinance with rates now being under 3%? Can I refinance even though I don't have much equity? I don't know if I would qualify given my situation. With a doctors loan I have no pmi but at 2.98% I would lower my monthly mortgage by about $400. This would be a great advantage as I plan on turning this into a rental after living in it for 2 years. What are your thoughts? Thank you in advance.
