How do multiple credit cards affect ability to get loan?

[Hae-Yuan Chang]

I'm really into getting reward cards for the points. I always pay off my balance, and as a young investor, I have a 760 credit score (lower because of age). Not sure the route that I will take for my second rental property, whether it be hard money lenders, seller finance, etc. But I was wondering how having multiple cards look to any type of lender, if it matters at all? Or does credit score only matter? I only have 3 cards now, but I would love to get a few more for rewards and close some out in the process (churning). Any experience with this would be great!
