Like Debbie said you would get back the 20% downpayment, any principal that was paid during the year and prepaid taxes in your escrow minus closing costs and realtor fees (if any). I would be happy to sit down with you to discuss your options as well as give you a CMA (comparative market analysis) of your home. I myself live and work in Latham so I'm very familiar with the area. Feel free to call me at 518-378-8756. Chris
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.
