Separate checking account for each rental?

[Mindi B.]

I am closing on my second rental prop next month and want to use an LLC for asset protection. In order to receive rents and deposits I'll need a business checking account.

From what I've learned each property should be a separate LLC and checking account. If I acquire 10+ properties, do I need a checking account for each one? What do people do when they have 50+ properties??
