Should I refinance or sell?

[Jasmine W.]

I'm looking for some advice...I purchased a 2 unit building 3years ago I live in one unit and renting out the other which pays almost all the mortgage. I'm ready for my next investment but also ready to move into a house (not wanting to house hack anymore). My multiunit is worth about 250k now of which I owe 143k with a 4.25% interest rate. I been getting offers to refinance at 2.75% so should I refinance or sell to purchase a bigger unit and a house? I'm at a stand still and don't know what to do HELP!
