Another interest rate cut on tap. The Fed expected to announce today it's cutting rates a quarter of a percentage point, marking the 2nd cut since July. Bankrate's Greg McBride says this is good news for both home owners and home buyers. He says it's a great time to refinance and mortgage rates will drop even below the 4-percent they are now. He says the economy is on solid ground, a recession is always possible so you should be saving money every month, but it's not on the immediate horizon.
