I think I made a mistake. Question abt finding deals

[Steve S.]

Ive been fortunate to have accumulated a fair amount of cash. When I've made my purchases of SFH rentals, I've typically written a check for about 25% down. I've come to realize a better way may be to add a lien on equity in a current property as collateral for the down payment against the next property. This would prevent me from having to tap into my cash for subsequent properties. Can someone explain to me how to do this? I'm binging and googling for some good links as well.
