Best way to leverage paid off properties
Hi,
I've been buying and holding my rentals for 6 years now (mostly duplexes) and have poured money into paying them down and off. Currently have 4 out of my 8 paid off. I want to purchase more and maybe get into something bigger like 4 plexes. My question is how best to leverage my props? I don't have much saved up for a down because I've been throwing cash at the mortgages. Any advice?
