Tax Returns and how they will affect getting new loans

[Asher Anthes]

I'm about to file my 2013 taxes, and I was able to show losses on both of the properties I own after writing off depreciation, interest and repairs ect.

I will be applying for multiple mortgages later this year, and my concern is will those losses negatively affect my DTI ratio and my ability to get new loans.

How do they use my tax returns to caluculate income? Will they go off the Adjusted gross income or will they use my lease agreements? I've also heard that they will not account for expenses such as depreciation and interest, is this true?
