New to Forum - General Advice

Hello

I'm new to the forum here and I'm glad I came across such a great site.
I'm 30 years old and I own a double in Kenmore, NY (suburb of Buffalo). I purchased when I was 23, lived in it and now rent out both units while I live in DC working in Property Management. I have to say, I love having people pay my mortgage and leave me with $300 extra every month. After reading so many books and websites I'm ready for more. Here's my issue. Where can I come up with the extra money to purchase my next double in the same area. Kenmore, NY is loaded with low purchase price doubles in great condition that pull in great tenants due to the area and decent rents. Where can I pull out the money I need to purchase my next one...or even purchase an 8-10 unit? Any comments or advice appreciated.
