Instead of 40 houses cash flowing $200 each or $8000/month, you buy 10 houses and pay them off for a cash flow of $10,000/month with 1/4th the headache.People don't understand the amount of time, energy, and stress involved with managing a lot of doors, especially if they are lower-class properties typically needed to generate cash flow.

It depends.If you find a PM that is willing only to do some task becaue you're still very involved then go for price.If you're looking for a PM that will ease the stress to where you forget you're even a landlord then quality of service is key not price.
