Why Closing Cost results differ in Vermont

The top 5 reasons results differ
Run this scenario in DocketMath using the Closing Cost calculator.
Closing Cost is a deceptively simple calculator, but in Vermont the outputs can diverge because small input and rule-handling differences compound quickly. With DocketMath (jurisdiction-aware for US-VT), the goal is to make sure you’re comparing like-for-like—not just re-running the same numbers.
Below are the five most common causes we see in Vermont.
You’re not actually using the same “lookback” window
- Vermont’s general/default limitation period is 1 year.
- If one workflow is using a 12-month window and another is using a different window (even 18–24 months), closing cost totals can swing meaningfully.
- Rule basis (general/default): The briefing provided indicates the applicable limitation period used by DocketMath here should be the general/default 1-year approach (no claim-type-specific sub-rule was identified). For background on the Vermont context provided, see the briefing materials: https://legislature.vermont.gov/Documents/2020/Docs/CALENDAR/hc200226.pdf
**Event date mismatch (filing date vs. sale/closing date)
- Even when the “same” matter is involved, teams sometimes key off different dates:
- date the underlying event occurred
- date the matter was filed/recorded
- date an update was entered in a system
- DocketMath’s closing-cost logic will react to the date you feed it, especially when limitation/lookback logic is in play.
Different treatment of “what counts” as a closing cost
- Some sources include recording fees; others exclude certain third-party charges.
- If your dataset classifies fees differently (or you’re importing from two systems with different fee categories), your totals won’t reconcile.
Interest/charges included vs. excluded in the input bundle
- Closing-cost calculations often bundle fees with additional charges.
- If one set of inputs includes taxes, service fees, or similar add-ons while another omits them, the difference may look like a “rule” problem when it’s really an input-composition problem.
The jurisdiction rule used is not the general/default rule
- For this brief, no claim-type-specific sub-rule was found.
- That means the system should rely on the general/default period of 1 year for limitation handling in Vermont.
- If your process (spreadsheet, internal memo, or another tool) assumes a different claim-type-specific rule, results will diverge.
Note (non-legal advice): Don’t assume “same jurisdiction” means “same rule.” In this Vermont setup, the most frequent reconciliation failures come from whether the workflow uses the general/default 1-year period versus a claim-type-specific assumption. The guidance used here is the general/default approach because no specific sub-rule was identified in the provided briefing.
How to isolate the variable
Use a short, structured diagnostic pass. You’re looking for the single input or rule toggle that changes the outcome.
- Freeze the jurisdiction and tool settings so both runs use the same rule set.
- Compare one input at a time (dates, rates, amounts) and re-run after each change.
- Review the breakdown to see which segment or assumption drives the difference.
Step-by-step checklist (fastest path to a match)
- Pick one event date standard and stick to it across runs.
- Ensure DocketMath receives the same date field every time.
- Vermont: General SOL Period = 1 year (general/default; no claim-type-specific sub-rule found in the briefing).
- Reference: the briefing materials provided for this content include Vermont context here: https://legislature.vermont.gov/Documents/2020/Docs/CALENDAR/hc200226.pdf
- Make sure both runs include/exclude the same fee groups (e.g., recording fees, service fees, third-party charges).
- If you can, export the inputs for both runs and diff them.
- Run DocketMath once with the original inputs.
- Then change only:
- the date, or
- one fee category, or
- one add-on charge
- Stop as soon as the output aligns—or flips in the direction you expect.
Quick diagnostic table
| What you changed | Expected effect on Closing Cost output |
|---|---|
| Move date forward/back within the year window | Output should change proportionally (not randomly) |
| Expand/contract the time window used | Output can jump noticeably due to timing-based logic |
| Add/remove a fee category | Output should shift by approximately the added/removed total |
| Include/exclude add-on charges | Output changes should track that add-on list exactly |
Next steps
Re-run with “controlled inputs” in DocketMath
- Use the same:
- Vermont jurisdiction selection (US-VT)
- event/trigger date
- fee inclusion list
- add-on charges (yes/no)
Record the rule basis you’re applying
- For this Vermont setup, anchor your process to the general/default 1-year period and avoid claim-type-specific overrides unless you have verified authority for them.
Validate against a single known reconciliation pair
- Choose one matter where you can confirm:
- the correct date used by your source of truth
- the exact set of fees included in “closing cost”
- Aim for consistency first, then expand to the broader dataset.
If results still differ, check silent data issues
- time zone formatting
- truncated dates (YYYY-MM-DD vs full timestamp)
- duplicated fee rows in one import
Pitfall: If you change multiple inputs between runs (date + fee categories + add-ons), you won’t be able to tell whether the divergence is a rules issue or a data issue.
