I had a house with a retired lady, no PM. Realtor bought the home warranty. Last summer AC broke while I was in China, got it fixed with the home warranty for $60. Switched to another one (old republic) after this one expired. They have a 1 month waiting period. Then two weeks ago leak under sink, again $60.
Overall it is OK for me. I wish I bought it for another house that had a lot of issues. Would have saved some money.
