Hi Iahmed

If you sold after living in the house for 1 year at the same price you paid, you would basically get back your 20% downpayment of $60,000, plus a little more that was paid off towards the principal over that 1 year period. I don't have those exact figures, but it might be a few thousand dollars (rough guess - $3000).

That's all the equity you'd have.
Keep in mind, if you listed with an agent, and had to pay a commissiion, obviously, you'd have to subtract that commission and any other closing costs to come up with a final figure.
