Business credit card

[Account Closed]

Hello BP.  I am just starting to develop a real estate portfolio and I would appreciate your advice with reference to tracking business expenditures.  I have not done a single deal, but will enter real estate with single family home properties.  Should I get a business credit card, or should I just use my personal credit card for business?  Of course, my concern is asset and personal protection.  If getting a business credit card is the way to go, I'd appreciate suggestions as to which card I should look into (or are they all about the same?). 

Thank you in advance, 

Chris
