Can I get a loan if my DTI is low now, but it was high last year?

[Peter Surowski]

Last year, I was living in my primary residence and working on a flip for much of the year. Since I had a house that wasn't generating any revenue, my DTI was about 55 percent, as shown on my 2020 income tax returns. But this year, I no longer have that flip, so my only house that's not generating revenue is my primary residence. My current DTI is 45.

I'm trying to get a home mortgage to buy a new primary residence. I know a DTI of 45 is still a little high, but I'm told it's passable. But will my DTI of 55 that I had last year sabotage my chances of getting a traditional primary residence loan?
