How to Appraisals work?

[Basit Siddiqi]

Hello Everyone,

I am here wanting to fully understand the appraisal process and I would be appreciative if anyone can give me feedback.
I am also appreciative if anyone can provide some resources such as articles or books to understand the topic more.

Below are some of the questions that I had.
1) Do appraisers go inside the property that is being appraised?
If they don't - Are the insides of the property not considered when looking at comps?
2) If I am looking to do the BRRRR - what is the number one thing that I can do to increase the appraised value?(not including adding square footage)
3) What is the total cost of doing a refi? outside of the cost of the appraisal - do you have to pay for items such as a loan origination fee, title costs relating to recording a mortgage, etc

I appreciate everyone's help!
