Refi or not?

[Roger Mbah]

Hello, 
I'm new to the platform and have a newbie question. So I've been in my primary home for 2.5years. When I bought it, interest rates were really good so I ended with an interest rate of 2.83%. I also did some rehab by adding an ADU to the basement. I also spruced up the first and second floor to suite my taste. Recently, I installed solar panels on roof. So as you can imagine the property has accrued a decent amount of equity. So now that I turned on my real estate investment switch, I'm thinking, should I refi, pull out part of the equity and use that as down payment for my next property? The main concern here, is I'll be jumping from 2.83% interest rate to over 7% interest rate.
