I would agree with Bugs. However, if you want to do a more involved analysis here are the steps I would take…
1 – If you were to sell your home, take a WORST case look at the sale. You said you think it would list for x $. What did you base that on? Have you looked at solds or actives? Have you looked at the number of expired, cancelled and withdrawns? Make sure you are REALISTIC about what you would fetch NOT what you think it would go for.
2 – Calculate your net, [Sales Price – {Commissions + Closing Costs (use 1% as a swag here) + Prorated Property Tax, and loan payoff)}]
3 – Now as Bugs said, what would you do with the money? Say you played it safe and put it in a CD… So calculate your return on that investment for a few years.
4 – Compare that rate of growth to your CD verses your home on the market if the market were to dip and grow.
5 – Don’t forget to factor in the tax advantages as well you get by keeping the home.
I am not advocating one decision or another. I ALWAYS advocate running numbers though just to see if there IS a major disparity of taking one path verses the other.
If you have any trouble running the numbers I am sure people on this forum will be glad to help you.
