Also in ~13 years (possibly less) it surpassed all of them, how many years to have surpassed the average (I suspect less than 10 years). 

This is presuming someone with existing cash value, but the fact remains, $85,000 growing at 9% WILL catch up to and surpass $100,000 growing at 6%.

In this edition of NAAEI’s Apartment Jobs Snapshot, job openings in the apartment industry consisted of more than 37.0 percent of positions available in the real estate sector, surpassing the five-year average of 33.2 percent.Property management, leasing and maintenance job openings declined year-over-year, yet administrative positions increased by 1.1 percent.

But there have been many years ripe with scientific information on this, and the fall in water tables is surpassing all of the prior estimates. 

In order of importance:*Work less*Spend more time with family and friends*Get to 35 SFH rentals (5 more in 2015)*Surpass my flips from 2014 by profits not number of units

Surpassed the two year mark successfully which was a new milestone for me given the prior layoffs, ha. 

My wife more or less disliked my rentals until somewhere between them allowing me to quit my factory job and the point where my income from them surpassed her income.

I surpassed that number long ago and am simply passing time till I liquidate.The mistake many real estate investors make is basing their goals on generated monthly income from their properties.

Nothing wrong with flips as I do a few a year, but for long term wealth, rental property will surpass flips.  

By this time next year I will have surpassed my first number of $3,000/month in cash flow!
