For example, maybe you have very little to invest, so you have to flip at first to build up capital, then you recycle your flipping capital into BRRRRs, then later on your harvest your BRRRRs to get MORE BRRRRs and diversify into syndications. 

A few days ago, I found a post in a regional investor's FB group that I'd like some opinions on:Michael TurnerHello Everyone, Are you looking for a private lender, I’m providing all types of investment loans, with 5% interest rate, with no repayment penaltymichaelturner.privateloan@ gmail.com or Text/Call:+1724 7344256 (spaces added so BP doesn't think this is spam)What do you do to find out if it's legitimate or if it's potentially someone harvesting information to perform identity theft?

Where do you rank and how many motivated seller leads do you harvest/day... these are metrics that matter.I agree with you that as someone not yet established on the net should not just do SEO... 

Around where I am from in Maine most of the deals made are they will come and log or clear your land in exchange for the profits from the harvested timber.

Would it be helpful to know if the land has trees that can be harvested too? 

Remember, in these old houses, lumber was milled locally, in many cases on-site, and frequently by hand, so why would you invest effort to mill a support pier that will be unseen in the basement when it makes no difference to its function.As Brian indicated, houses were built experientially back in {pre}Victorian era and lumber was not graded as it is today - mind you, much of the lumber was of a far higher quality than what we harvest these days.The key thing to look at is whether these unmilled piers are set directly in the soil or if a footing (likely stone, but possibly concrete) was put underneath it.

also I could harvest the lumber.

Also, don't forget about tax harvesting for next year.

Exchange, Harvest the equity when possible ... then continue to    "Swap Until You Drop" ... avoid Capital Gains Taxes forever. ( Or until they change the 1031 rules )

Otherwise, you'll just attract controversy and you'll only harvest conflict for yourself.
