Quality vs. quantity

[Dan Heath]

I'm curious of thoughts out there regarding buying a few good quality properties and focus on debt paydown and highest and best (HABU) vs. accumulating mass quantity of rentals. It seems to me like a logistical nightmare to have 30 doors each only netting $100/mo  = $3,000 vs. owning 5 doors, bought with existing equity, large down pymt, and each door netting $600 = $3,000; with a focus on maximizing the best possible use of the property. Maybe converting it into something that will produce more income. Most of the BP podcasts I've listened to have focused on the number of doors. 

Let me know your thoughts. 

Thanks!
