Loan to convert 2 family to 3 family

[Nelson Amalbert]

I currently own a 2 family that I want to convert to a 3 family. I’m working with an architect now who believes it can be done and approved by the city. My question is, because this conversion would add value to the house, will lenders be pretty likely to fund the project? Personally i am already looking at consolidating some personal debt. (15k) but my credit is still good (700’s) will my debt to income ratio be a major factor here or will the equity put in the house suffice for approval?
