Too many think that "quantity", because of the volume, will generate those leads simply because there are so many...there has to be at least one "needle" in that stack of plenty. 

I go for quality over quantity.

Increasing job quality and quantity - You need new employers setting up operations.Investor friendly - Check for rent control (os similar restrictions) and the actual cost and time to evict.Property cost - There is a tendency for new investors to choose locations with very inexpensive properties.

Demand is not constant.Elastic demand is one in which the change in quantity demanded due to a change in price is large.That happened during the recession, as the price is too expensive, people prefer to save money and not buy mortgage because the mortgage is more than rent right now, so the demand could pretty much collapse during mortgage hikes.

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

This enables them to buy cheaper properties, larger quantities, take more risk, etc.

A mix of many assets in conservative quantities arguably is the safest way forward.
