The Orthodox Jews in NYC (and I am sure elsewhere) have no issues transacting millions of dollars of business each and every year on a flip phone.The tech for solar panels is just not there.  

And I also can definitely point to what you would call my Orthodox Catholic upbringing for that.

A little un orthodox but,  make sure to frame and put sheeting on the outside of your garage. 

It's not just Sharia but orthodox jews and others that have similar structuring requirements as far as not paying interest.

I have found the information thus far on this website to be fantastic, and have already incorporated the House Hack and the BRRRR into my book based on what I have learned here.My prior writing has been in the area of Biblical Fiction (I'm also an Orthodox Rabbi), but lately, I've been expanding into the area of personal growth novels.

My marketing techniques are somewhat un-orthodox.

But the offense that it gives you may just be interpreted as a value judgment on your tenant's part.For instance, as a practicing Greek Orthodox Christian, I am most grievously offended by much of what my tenants do.And yet I've never brought up any of this with them.

Our Russian orthodox subs have more religious holidays than I can even keep track of .. so same thing you roll up its Thursday were is Dimitri  OH its a religious holiday and no way they are working. 

we have one  black/white couple   One lesbian couple  One non English speaking Hispanic couple one white/Chinese couple with their Chinese parents living with them One Russian Orthodox folks dress like Amish and 3 police officers that decamped from Portland.. and one lives next to the mixed race couple and is good friends with the husband that the black partner  And I am proud to say each and every family is outstanding their homes immaculate and we have the highest priced development in town by about 10 to 15% over our competition.
