Hi and welcome to the forum
IDK the answer but wanted to respond to bump your post up to today.
However, I do have some questions:
What amount of loan are you seeking?
Do you have a minimum of $10K down?
Do you have funds for closing?
Do you have Bank statements proving you can make monthly mortgage payments?
Hopefully, an expert will come along soon.
Having only 16 months self employment isn't necessarily a deal killer. You could wait another 6 months and file your 2nd year of taxes and hopefully not take so many deductions this year know you can qualify now for a Conventional loan using just your last reported 1040 instead of two years. Or there are a number of NonQM Loan products available to you now, that are designed for borrowers with your scenario. You have options.
Hope this helps you.
