Business Name, LLC, Personal Name?

[Nathan Arnold]

Hi! My name is Nathan and I’m considering making my first deal as a Real Estate Investor. I’m very strict on organization and would like to have separate accounts for my rentals and my personal finances. Since I will only have one rental to begin with, I don’t see it profitable yet to get an LLC. However, I have considered simply getting a business name and have my accounts opened in that name. Should I go through the work to do this or just open another account in my own name? Have any of you made a business name as a sole proprietor without an LLC? I’d like to hear your opinions and additional info. Thank you!
