The industry standard currently is around 70%, but there are some that will go up to 75% or 80%, but you've got to have pristine credit.

Properties also have specific risks depending on if they are industrial spaces, commercial buildings or multi-family units.

Totally useless for making go/no-go decisions, just like the average-only market stats from RedFin & Zillow.Stay away from AI, demographic data, and average-only market data/stats if you want to "make a data driven decision towards purchase", they are all too broad/meaningless to actually help make that go/no-go decision.

If you’re looking to invest in your backyard, it helps to network with as many locals in the industry as you can.

You can also create a basic scope of work and get ballpark estimates from contractors or use cost-per-square-foot averages for your area.To determine ARV, look at recently sold comparable properties in the area that are similar in size, style, and condition to what your property will be post-renovation.

The one you can scale.I know successful business owners in the fitness industry, tanning salons, real estate, window coverings, maintenance, billboard, ATMs, etc.Generally, I would be skeptical of jumping into a business based on YouTube videos hosted by and featuring people that are likely primarily trying to sell you their respective courses.Small businesses can indeed be great investments, but they are hard.  

Fast forward my entire career has been in construction from residential to commercial to industrial. 

Also, post industry articles.

@Chris Blackburn, while I can't speak to this specifically, there are a few red flags I see in your post.1: A Realtor has to be a member of the national association of realtors, an industry trade group primarily focused on your typical home buyer.
