Business Name and Contact: Is it safe?

[Emily Carling]

When starting out in real estate, is it legally safe to contact prospective sellers under a company name, even if it is not an LLC, SP, etc?

For example, there is an abandoned property just conveniently one door next to me. If I were to contact the owner (found through local govt website) with a written letter, would that be okay? Can I even ask about the property if I don't have an LLC or other entity?

Thanks!
