Quality > Quantity is the key hereI know guys with lots of doors who bought subpar stuff and they generally pay for it one way or the other (bad tenants, losing money on liquidations etc) because, more often than not, emotion (As Jon Kelly said, fame of a 1000 doors > 20 doors) gets in the wayBeing well capitalized (partners, LOCs etc) is great but what's even better is when you buy a deal with solid financials and fairly low, well-measured risk going into it

In my market you can drop two deals a year and easily net half a million - so I focussed on quality and not quantity.

Just doesn't work that way.If you want to grow with quantity/volume, have deep pockets and re-circulate capital in high RTP areas and get a few houses a year.

Quality over quantity guys. 

Nope..... the credit they receive rarely meets the quality or quantity of work they perform.IF you have someone you truly feel is qualified to do the work, then hire them to do the specific work..... that $$ is TOTALLY separate from the rentGuy mows lawn for a living...ok....what do you charge per house?......

What instantly struck me was Engelo wasn't interested in building his business through quantity of customers, but was after quality.

They provide a large quantity of goods at very low prices. 

Any wholesaler who is doing a lot of real deals will tell you have need quality buyers over quantity.
