How to Expand Rate of Rental Acquisitions in $35,000 Range?

[Tony S.]

I'm finding success buying, rehabbing, refinancing and renting out homes in the $35K range.  I'm currently working on my second investment property, but am dissatisfied at the pace I'm going. 

My current rate of acquiring 2 rentals/year is falling short of my 6 rentals/year goal.  The deals are out there for my niche market, but shortfalls in funding is slowing me down.  

Has anyone in a similar situation successfully jump-started their expansion?  If so, I would like to hear from you on creative strategies or ideas to help expand the volume of rental acquisitions.
