Estimates are model-driven opinions of value — not appraisals.
The number is only as good as the data behind it.
Every estimate is triangulated, not guessed.
A single model can be confidently wrong. compbird locates value the way a careful appraiser does — by cross-reference, and by showing its work.
The comps are chosen, not scraped
Candidates are ranked on distance, structure, recency, and condition — then atypical and distressed sales are flagged out before a single number is drawn. Six survivors, not sixty look-alikes.
Five independent reads, one subject
The prior sale trended forward, a direct comp adjustment, a straight $/sqft read, an acreage residual, and a trained valuation model each price the home on their own terms. No method sees the others, so they can't quietly agree.
Their spread is the confidence
When independent roads arrive near the same address, the estimate holds. The gap between the high and low method is published as the spread — and the number below is a real engine run, not a mock-up.
How $455,000 was derived
No MLS-confirmed prior sale (assessor deeds are not trusted as anchors).
Top 3 comps (1461 Walnut Ridge Road / 1041 ST CLAIR Lane / 1441 Walnut Ridge Road) median time+size-adj $211/sf × 2,096 sqft = $443k = $443k.
Median time+size-adjusted $219/sf × 2,096 sqft = $459k.
Comp improvement avg $220/sf; residual land rate $40,242/eff-ac. 2,096 sqft + 0.3 ac (≈0.3 eff-ac) → $472k.
Skipped (fast / interactive mode).
Independent methods, one verdict.
five methods land within 6.5% of one another on this real engine run — the spread is published with every estimate, never hidden.

Everything you need to defend a number.
Appraisal-grade comparables
Every comp is ranked by true similarity — size, age, lot, distance and recency — then weighted, not cherry-picked. Six defensible sales, located in about a second, the way an appraiser would choose them.
Similarity-ranked, recency-weightedLive price-per-sqft
The neighborhood unit price, recomputed as sales close — never a quarter behind.
Atypical-sale detection
Auctions, distress and off-market outliers are flagged and down-weighted, so they inform the number without dragging it.
Branded PDF reports
Export a clean, presentation-ready dossier under your own name — figures, comps and the map, on one page.
Freshly synced data
MLS listings re-sync hourly and county records refresh daily, so the value you defend is current — never a quarter behind.
Statewide coverage
One graph spanning every Virginia jurisdiction — statewide assessor parcels joined to live listings.
Built on Virginia. Expanding out.
We went deep before we went wide. The parcel graph spans all 133 Virginia jurisdictions — every lot joined to its county or city assessor record, so a valuation knows the structure, the last deed, and the street it sits on, not just an address.
Deep live MLS runs in about nine jurisdictions today — the New River Valley core — and widens as each market’s feed comes online. Recorded closed sales from public records back the comp pool across 130 Virginia and D.C. localities, so rural valuations lean on nearby sales even before a market’s feed lands. Listings sync hourly and county records refresh daily.
