Lines of credit or mortgage?

[Joshua D.]

So since I started I purchased my first 2 properties with cash. First one a duplex with $22,000 all in and cashflowing $700 a month. Then a SFH for $30,000 all in and cashflowing $400. I then took a line of credit out on my SFH and got $75,000 I could use and rolled that into 2 other properties. Then took line of credit out on duplex for $44,000 and rolled that into 2 other properties and continuing that process which now have 8 all together. Am I doing this right?
