Newbie trying to understand how to scale

[Jennah Sontag]

Let's say I purchase my first door with a conventional loan. Then to get my 2nd door, is it better to finance with another conventional loan or get a line of credit by borrowing off my first property (then get a line of credit from my 2nd door to put toward my 3rd door and repeat the cycle)? I don't understand the risks involved with either approach to know which is better. Thanks for any insights!
