I want to make sure I do this correctly from a tax standpoint since all I'm making is a flat fee.

If that’s correct, here’s my non-expert opinion. 

I found a property on an auction site that I'd like to bid on.

But all of the A/B class areas or rapidly growing cities do not have much at all, and when they hit they get bid up.

In a busier place, you might just be told to find a GC to "un-cluster' what you did.For me, when this happened, I had to go and hire a certified plumber, and electrician, and framer to come in and certify that all the work my handyman did was correct - and to fix the issues that weren't correct.  

Correction: This episode talks about Price Labs https://open.spotify.com/episode/1bS4eL80KL1rWY4vyCMjXh?

I had to look up what "variance analysis" meant.If I understand the question correctly, you're asking "What went wrong to not hit our 20% target?"

HOWEVER; if you aren't going to use your full last name, then it's important to upload a pic to your profile (which you have) The reason being, when someone has a common name, with an initial and you are trying to @mention them, if you have a list of 5 David R's with the stock icon, it's impossible to know which is the correct one. 

It took a few months to correct it but they finally did.

Is that correct?
