Home Price Offer Calculator
Get a data-driven offer range based on list price, days on market, comparable sales, and market conditions — with acceptance probability at each level.
How to Use This Home Price Offer Calculator
Choosing the right offer price is one of the most consequential decisions in a home purchase. Offer too low and you lose the home; offer too high and you overpay. This calculator combines market data, days on market signals, and comparable sales to give you a calibrated offer range with acceptance probabilities.
Quick Calculator — Offer Range
Enter the list price, days on market, comparable sales average, and market type. The calculator returns a low, mid, and high offer with the approximate acceptance probability at each level, plus a quick verdict on whether the home is overpriced, fairly priced, or underpriced relative to comps.
Advanced Tier — Strategy, Comps, and DOM Signals
The Market Strategy tab shows recommended targets for each market type. The Comp Analysis tab lets you enter your comp range to find a precise fair value. The Days on Market tab explains the DOM discount playbook from fresh listings to stale inventory.
Pro Tier — Negotiation, Competing Offers, and Total Cost
The Negotiation Framework tab models the typical three-round process: initial offer, expected counter, and settle point. The Multiple Offer Strategy tab covers escalation clauses and appraisal gap coverage. The Price vs Concessions vs Buydown tab compares all three strategies across a 30-year hold period.
How the Offer Range Is Calculated
Days-on-Market Discount: 0–14 days: 0% | 30–59 days: 3% | 60–89 days: 7% | 90+ days: 10%
Combined Adjustment = Market Adjustment − DOM Discount
Low Offer = List Price × (1 + Combined Adjustment% − 2%)
Mid Offer = List Price × (1 + Combined Adjustment%)
High Offer = List Price × (1 + Combined Adjustment% + 2%)
Comp Signal = (Comp Average − List Price) / List Price × 100
>3% above comps = Overpriced | Within 3% = Fair | >3% below comps = Underpriced
Example: Offering on a Home in Austin, TX
Marcus offers on a 3BR/2BA home listed at $485,000 — 42 days on market
Marcus is buying in Austin in a balanced market. The home has been listed for 42 days. His agent pulled three comps that averaged $471,000, suggesting the home is listed about 3% above market value.
| List Price | $485,000 |
| Days on Market | 42 days |
| Comp Average | $471,000 (home is 3% overpriced) |
| Market Type | Balanced |
| Market Adjustment | -2% |
| DOM Discount | -3% (30–59 days) |
| Low Offer | $451,000 (~35% acceptance) |
| Mid Offer | $461,000 (~60% acceptance) |
| High Offer | $471,000 (~80% acceptance) |
| Marcus's Strategy | Offer $461,000 anchored to comps; request $5,000 closing credit |
Marcus offers $461,000 with a $5,000 closing cost credit request, referencing the three comps in his offer letter. The seller counters at $475,000. They settle at $467,500 with a $3,500 credit — $17,500 below list price.
When to Offer Below, At, and Above List Price
- Below list (buyer's market or stale listing): When inventory is high, homes are sitting, the list price is above comps, or the home has been listed 30+ days without a price reduction. Use specific comps to justify the discount — it shows you are making a market-based offer, not a lowball.
- At list price (balanced market, fairly priced home): When comps support the list price, the home is within 7–14 days on market, and you want a clean offer without friction. Standard contingencies are appropriate.
- Above list price (seller's market, multiple offers expected): When inventory is low, the home is priced right or below comps, and you expect competition. Use an escalation clause rather than guessing a number. Cap your ceiling based on your maximum affordable payment, not emotion.
