Which zip codes i should need to focus on in order to do wholesaling virtually? 

Don't forget that many local codes may also require closets to be considered as bedrooms even though that is not part of international building codes.

That's code words you tell yourself to justify not moving forward with any meaningful action.   

We give out Pro discount codes for those who attend.

@Anna Hummer is there a reason you're only interested in one zip code?

If you can, well then you can give it a shot.Also, if you are looking in a major metropolitan area, be prepared for rapid changes to the code that could prevent non-owners doing it to eliminating STR's all together.

It is very important to know all major mechanical are up to code.

Another fun thing we have done is the key box we stick on doors for a house , put something fun in there, a surprise, and give the kid a code.

The biggest hurdle for us at the time was that we have a flat roof and investigating the city's installation requirements for a flat roof seemed like the code requirement would just be setting you up for roof leaks. 

DJT is right- every American is entitled- and expected- to practice tax avoidance(via depreciation, 1031 exchanges, or whatever, the tax code legally allows) but tax evasion is a different animal.
