There is a "green" movement on these as well as it is a form of recycling.

Intel is a great example, who is building the largest chip manufacturing plant in the US right here, and it will be a $20 billion dollar investment that brings a few new thousand jobs.https://www.dispatch.com/story/business/2022/01/21/intel-ohio-building-computer-chip-factories-licking-county-jersey-township/9173472002/ Here are a few more recent investments https://www.10tv.com/article/money/business/hydrogen-power-company-hyperion-bringing-700-jobs-to-columbus/530-25907aab-5517-4661-a9f3-d2ed2d5be6b0 https://news.wosu.org/news/2022-02-08/rumpke-to-build-50-million-recycling-facility-in-columbus

If the appraiser thinks/states they will violate USPAP by providing a limited valuation and tells you they can only do a "full" appraisal or the like, they don't know what they're doing or are just trying to milk your money.

Those assets are really just recycled product that has a very short shelf life for investors.

Sorry Roy, We in Toronto had milked all we could out of this cow, we are kliing eachother for a peace of 100 year old property selling for 700K that needs a total gut and 100K of renos and paying 150K over asking price, competing with 10 other people on the same property.But think about the positive side of it, we are going to start buying where you live and your properties are going to appreciate like never before because of the competition, free money without working, isn't that nice?

Personally, I prefer to see the material taken for recycling by those guys than hauled to a landfill.  

Most simple thing, do math for both hypothetical situations and see which one brings you more money, consider rent you will pay, and the interest you will pay for heloc for cash out, and whether you can finance the new properties or not.I personally would never sell a SFR in an appreciating location so I can milk it during every cycle.

Thus the recycling side of it is becoming more profitable...

I guess they just recycle their capital for each sfr and then replace their capital with the bank's capital.

You are confine to the fields they provide for you which is very difficult.Most of their data out dated and they keep recycling it.
