Tax Loss Harvesting Implications on Mortgage Qualfications

[Zeb B.]

I have about $50,000 in unrealized stock market losses in my taxable brokerage account. I'm considering selling some of these securities for tax loss harvesting. I don't plan to change my exposure to equities, the proceeds from the sales would be reinvested in similar manner (without violating wash sale rules). 

My question is, if I harvest $50,000 in losses this year, will that loss reduce my income available to qualify for conventional mortgages? I'm not currently planning on taking out any more mortgages in the near future, but I don't want to box myself in to a corner in case an opportunity to buy or refinance a property arises.
