Moving to big apartment buildings - 10-20+ units

[Jason Tham]

Hello!  Do you invest in apartment buildings with 10 or more units?  I'm now going into my 4th year of real estate investing, and my portfolio to date includes multifamily, single family, and an 8 unit partnership.  I'd like to break into the 10+ unit complexes.  My 8 unit has made me realize the synergies (i.e. only 1 building to manage tenants and repairs on vs. many single/multi-families), vacancy buffer benefits, and opportunities to raise rents per door.

Can anyone share their experience with me of moving to apartment complexes?  How did you evaluate the numbers differently?  How did you change your deal evaluation techniques?

I'm also interested in finding investors to cover the capital needs up front.  Anyone have experience with this as well?
