Home valuation is one of the most important parts of real estate, and one of the most misunderstood. Buyers lean on a Zestimate. Sellers go by what the neighbor's house sold for. Neither is a valuation.
A real valuation shows its work. If you know how to read one, you walk into a negotiation knowing what the house is worth, why, and where the other side's number is weak.
Why valuation matters
- Buyers who don't know a home's real value overpay, or lose the house by guessing low.
- Sellers who guess wrong either leave money on the table or sit on the market while the listing goes stale.
A good valuation helps you write a smarter offer, spot your leverage, justify a counteroffer, and avoid a low appraisal blowing up the deal in escrow.
What a real valuation report includes
1. Comparable sales
Recent closed sales in the same neighborhood, as close as possible in size, bed and bath count, lot, age, and condition. For a condo, the best comps are in the same building or a directly competing one. Closed sales are the evidence. Everything else is context.
2. Pending sales
Homes under contract show where buyers are committing right now. They're often a better read on today's market than sales that closed three months ago.
3. Active listings
What's for sale is your competition. If five similar homes are sitting at a higher price, that tells you something. So does a lack of anything comparable.
4. Adjustments, explained
No two homes are identical, so every comp gets adjusted up or down for real differences: a remodeled kitchen, a pool, a view, an ADU, a bigger or more usable lot, a busy street. A good report says what was adjusted and by how much. "Adjusted for condition" with no number is not an explanation.
5. A range, not a single number
Value is a range. A strong report gives you a conservative, likely, and aggressive number, and explains what would put a sale at each end.
A note on price per square foot
Many reports lead with it. Treat it as a rough sanity check at best. It ignores land, condition, layout, floor, view, parking, and HOA costs, and the square footage itself is often wrong. We wrote a whole piece on why: Why Price Per Square Foot Is the Most Misunderstood Number in Residential Real Estate.
Red flags
- Old comps. In a moving market, sales from more than about six months ago need a clear time adjustment.
- Comps from the wrong area. A sale across a school boundary, a freeway, or into a different building is a different market.
- Missing differences. Upgrades, condition, permits, and lot quality left out of the adjustments.
- Round-number pricing. A suspiciously clean number with nothing behind it.
- No reasoning. If your agent can't explain how they got the number, get a second opinion.
How we do it
Every Arrivva buyer and seller gets a data-backed valuation with a full range, the comps behind it, and the adjustments spelled out. Buyers see it before we write an offer. Sellers see it before we set a list price, alongside the inspections we pay for up front.
It matters more with us because of how we're paid. Buyers pay $9,750 flat and sellers pay $15,750 flat. We earn the same whatever the price, so the valuation has no reason to lean high or low. It's just the number.
The bottom line
A valuation is a strategy document, not a guess. Know what's in it, check the comps, question the adjustments, and use the range. That's how you avoid overbidding, underpricing, or missing the window entirely.
