Lightbulb Electrical Wiring

I am selling my home and the realtor told us our outlets were "reverse polarity" so we switched the wires around to accomodate the buyer. Now, it is reading "open ground". Is this good or bad or indifferent?!

If the existing receptacles are grounding type (three-hole) yes they MUST be grounded. Some how I suspect someone replaced the polarized (two-hole) receptacles with grounding type without first checking to see if there was a ground present at the box.+

If there is no ground present, you can legally install gfci receptacles. You only need one on each circuit. The first one can control the others on the same circuit.

It's possible to have "reverse-polarity" at receptacles even if all Grounding connections are perfectly sound and it's possible to correct this situation at only one point where there might be a Black-to-White "cross-over". Much depends, in correcting your problem, on the age/condition/type of the existing wiring, such as metallic or non-metallic boxes and cables. Perhaps you could provide this info.-----Good Luck!!!!

With most simple outlet testers, it is not possible to identify a reverse polarity without a ground present. This causes me a little concern in that you may have broken the ground while correcting the polarity.
