Refinancing to a lower interest rate

[Jorge Duarte]

I am currently renting my first property for $1100, I bought it with 5% Conventional down, $133,000 at 4.5% interest rate and my mortgage payment is $900 with solar panel lease payment of $140. I would like to get get a lower interest rate, in order to cash flow a little higher, and compound the return. With interest rates on an all time low, what are some things I should that I SHOULD consider before taking action?
