No point in looking at what you could sell it for unless you need to sell it.

Hopefully when you purchased you have a home you can afford and won’t sell at a bottom. If you bought a house in 2007 and held on to it until today you’d be fine, if you tried to flip it in 2008 or 2009 you’d take a big hit.

If you are planning on living there for a long time your concern should be affording your mortgage, nothing but stress and lost sleep at this point worrying you timed your purchase wrong.
