Did you use first class on the first batch and switch to standard after harvesting the bounced addresses to skip trace?

That is essentially no different than appreciation on a rental property (I will ignore 'equity harvesting' and similar strategies).

Hope you mailed first class on your first batch to harvest the valuable bounces.

The reality is that the broker in a traditional sale would not work as hard and would be extremely skeptical that they may end up sewing all the seeds but not reaping the rewards of the harvest.

Hope you used first class postcard first and harvested the bad addresses to skiptrace and stop mailing to those.

You don't have to sell to harvest the equity.

Do you want to buy and hold for long term passive income or would you like to harvest appreciation in 5 years? 

I use Janel at New American and Cindy at Harvest.

There are companies that can be hired to manage the entire orchard from planting, growing, maintaining, harvesting and selling the crop. 

There are quite a few western states that already regulate harvesting of rainwater, and that's likely to increase.
