Heat Pump vs. Gas Furnace

Does anyone have experience with a modern, efficient electric heat pump in the greater Houston, TX area.  A house I'm considering buying for a flip has a heat pump and I'm concerned.  It's a relatively new house, but from everything I've heard electricity bills are much more experience than gas heat (at least in the Houston area).  Any experience with this?  I'm concerned the expensive heat will scare away potential buyers even though we only use heat for a 3-4 months here.
