I’m not opening any more dermatology offices but I know a lot more about commercial properties rather than residential since I am a tenant in 6 locations. 

So 4 units or less is considered residential, not commercial.

I am looking for recommendations for a GC that can build a 2BR 2BA home on a lot in a residential neighborhood.

If you are looking to invest in low-cost properties, whether they be commercial or residential, it is very important to consider the risks involved.

It's one unit off from your goal, yet obtaining a residential loan is much easier compared to a commercial loan.

Goal.This home sits on a .23 acres zoned residential with the option of changing the conditional use permit to multi-family.

Most of what I see on BP is focused on residential, but I'm curious if there are any forums or people I should follow for info about different asset classes?

Having worked in a W-2 environment for the last 20 years, I've now had my eyes opened to the incredible wealth building power of residential rentals versus the "quick fix" and subsequent tax bills from the land deals I've been doing. 

I focus on low-moderate income residential and have seen a huge increase in value across our holdings over the past 3-5 years, so we wrestle with selling all the time. 

There's probably a benefit to being an early adopter in that you take care of it before everyone else "has to" do it, but if you're too early then the infrastructure/products/know-how isn't there as much so you pay more than if you wait until demand is more widespread.Most folks I know, including myself, are taking a "wait and see" approach at the moment, but obviously folks that owner occupy might act earlier especially since it could benefit them personally.Now is a good time to recommend RISE Engineering, which does free energy audits of residential properties and then reduced-cost work if you do decide to implement some/all of their suggested improvements.My understanding is that it's free for the audit and reduced-cost for the work, because they get funded partly from charges everyone already pays on their electric/energy bills - i.e., it's subsidized by a tax we're already paying.
