Legal Considerations for Personal Company Name / Branding?

[Alex Persha]

Hello BiggerPockets Community!   Looking for input around - is there anything legally required to create a new company name and logo that I can use on a personal website, put onto a business card, email address, etc.?  Example - if I wanted to reference my solo real estate investment company as "Limitless Properties" that would be my company name, associated email address, website, etc.  Are there any legal implications or registration that is needed to make that official (ignoring the need to purchase the website domain, securing the email address)?

As I start out on my real estate investing journey here, I do not think it makes sense to immediately jump into creating an LLC, at least the first couple of years. However, I would like to have some personal branding and start to build name recognition.

Appreciate any insights and considerations around this!
