The answer to this question is a simple yes and no. Before the 2008 financial crisis, no-doc mortgages (now referred to as liar loans), were part of the recipe of what caused the housing market bubble. Banks were offering affordable interest rates to virtually anybody, even those who didn't have prime credit scores.
Imagine this: you walk into a bank with just Good or even Poor credit and end up walking away with interest rates as if you had a perfect score. When the other shoe dropped in 2008, the repercussions were ugly for many banks, and a lot of real estate investors as renegotiations and bank buyouts were happening every day. It's safe to say the "Wild West-Esque" days of 2008 are gone. However, some lenders are still providing no doc/ no income loans but at higher rates than you would've expected in the "golden ages." No-doc mortgages may not be as relevant as they once were. However, if you're self-employed or have highly variable income depending on the type of work you do, they are still accessible.
As we've mentioned above, there are a few more standards to meet if you hope to qualify. Still, inversely because of the financial crisis of 2008, you're now more protected than ever from predatory lending practices.
