Home Appraisal, arranged for the bank loan, was a quick 20 minutes.
I provided a list of all the upgrades we've done and the year of improvement, which helped.
Appraiser took pictures of the outside, then of each area of the house, inside. He knew we installed new windows, but didn't look at them. They tilt in to easily clean. He doesn't know that though. We made our high-end cedar shed, which values at $10,000. He doesn't know that.
Our garage has new wiring, but, he said, he didn't need to look in the garage. I thought that was a bit strange. There are some really nice 'mancaves' out there. We don't have one. So, this is for the bank. We paid for the appraisal, but, probably won't be able to see it. My only tips: clean and de clutter; log all upgrades; and point out the great things about your home.
