How to Prepare for a Home Appraisal
Most of preparing for an appraisal is cheap and low-effort. Here's what appraisers look for, the prep that actually helps, and what not to overspend on.

- Preparing for an appraisal is mostly cheap prep — cleaning, small repairs, access, and documentation — not big spending.
- An appraisal is a lender-ordered opinion of value from a licensed appraiser; a CMA is a real-estate agent's pricing opinion, not an official appraisal.
- Appraisers weigh size, condition, updates, and recent comparable sales the most; deferred maintenance and safety defects pull the number down.
- Don't over-invest in a last-minute renovation — most upgrades recoup only part of their cost and rarely appraise for what you spent.
If you've got an appraisal on the calendar — usually because you're selling or refinancing — the good news is that knowing how to prepare for a home appraisal is mostly about cheap, low-effort steps, not big spending. An appraiser is measuring what your home is worth to a lender, and a clean, accessible, well-documented house makes that job easier and removes reasons to come in low. Here's what actually matters in Green Bay and the rest of Brown County, and what's a waste of a weekend.
Appraisal vs. CMA — know which one you're getting
First, a distinction that trips up a lot of homeowners. A home appraisal is a formal opinion of value performed by a licensed appraiser, and it's almost always ordered by your lender as part of a mortgage or refinance — you don't hire the appraiser yourself, and their number can affect how much the bank will lend. That's different from a comparative market analysis, or CMA: a real-estate agent's informed opinion of what your home should list and sell for, based on recent comparable sales. A CMA is a pricing and strategy tool, not an official appraisal — only a licensed appraiser, usually lender-ordered, produces the latter. Both are useful; just be clear which one is in front of you.
What an appraiser actually looks for
- Size and layout: square footage, bedroom and bathroom count, and whether finished spaces like a basement are truly finished and permitted.
- Condition and updates: the age and state of the roof, furnace, water heater, windows, and electrical. Deferred maintenance and obvious defects pull the number down.
- Comparable sales: recent sales of similar homes nearby carry the most weight — the appraiser adjusts up or down from these 'comps.'
- Location and lot: neighborhood, lot size, and site factors specific to your street.
- Health and safety items: a cracked heat exchanger, exposed wiring, or a failing roof can flag the appraisal, especially on a financed sale.
How to prepare for a home appraisal: cheap prep that helps
- Clean and declutter. It won't change your square footage, but a tidy, well-kept home reads as well-maintained and makes condition easy to assess.
- Knock out the small, obvious fixes — a dripping faucet, a dead outlet, a sticking door, peeling caulk, a burned-out bulb. Individually minor, collectively they signal neglect.
- Handle curb appeal cheaply: mow, trim, clear the walk, a fresh doormat. First impressions frame the whole visit.
- Make everything accessible. Unlock the attic, basement, furnace room, electrical panel, and any gates — an appraiser can only credit what they can actually see.
- Write a one-page list of improvements with dates and rough costs: new roof 2023, furnace 2021, kitchen refresh, new windows. It makes sure real upgrades aren't missed.
- Pull a few recent comparable sales from your street or subdivision and leave them out. You're not doing the appraiser's job — you're making sure a strong comp isn't overlooked.
Don't pour money into a big pre-appraisal renovation hoping to 'boost the number.' Most upgrades recoup only part of their cost, and a fresh remodel rarely appraises for what you spent — cleaning, small repairs, and good documentation move an appraisal far more per dollar than a new kitchen. If a repair does turn out to be worth doing, get a quoted price against a documented scope before any work starts, so you're never spending blind.
