Your liquid assets can be used. Since this would no longer be your primary residence, once you're in the USA, then yes it "could be" considered liquid. Liquid assets like savings are treated much better. The savings would need to be 3 times the income shortfall, technically, but they will consider the thousands you'll spend relocating will NOT be available to support you, so much more is better.
Best scenario, is sell the house in the next year BEFORE submitting the I-864.
