Does it hurt your FICO score or chances of getting a home loan to have to many c

[DreamOutLoud]

I currently have the following in open credit cards

1. A Lee Michaels Card ( paid off, havent used it in 4 years)

2. Best Buy Card ( Paid off)

3. Visa ( Credit Limit of 11,000, we owe 2,700 on it.)

My credit score is 750, is keeping the Lee Michaels and Best Buy card open hurting my credit score? Will it look bad having them open even if they are paid off and are never used anymore to a bank giving us a home loan?
