Why Closing Cost results differ in Montana

The top 5 reasons results differ

If you run a Closing Cost calculation in Montana (US-MT) using DocketMath, you may see different “closing cost results” even when the same purchase price is entered. In Montana, the most common causes are input interpretation, jurisdiction-aware defaults, and timing assumptions.

Below are the top five reasons results differ for Montana outputs—grounded in how DocketMath applies jurisdiction rules and how the calculator treats common closing-cost inputs.

1. Different loan/transaction inputs

   • Closing costs often include line items driven by loan terms (e.g., origination-related items, insurance/escrow estimates).
   • If one run uses an estimate and another uses actuals, totals can diverge quickly—even with the same purchase price.

2. County/local variation being (or not being) included

   • Within Montana, recording-related fees and certain service charges can vary by location.
   • If DocketMath (or your workflow) applies a county-specific fee set in one run but not another, your total will change.

3. Rounding and fee-basis differences

   • Two systems may round at different steps (e.g., per-line rounding vs. end-total rounding).
   • Fees calculated “per $1,000” can behave differently depending on whether the calculator rounds before multiplying or after.

4. Inconsistent treatment of credits vs. costs

   • Lender credits, seller credits, and similar items can be handled differently across runs.
   • For example, entering a credit as a negative number vs. entering it in a dedicated “credit” field can shift the total.

5. Timing assumptions tied to Montana’s limitations framework

   • DocketMath may include jurisdiction-aware “timeline” logic that affects whether certain costs fall within an inclusion window used by the calculator.
   • Montana’s general statute of limitations (SOL) is 3 years under Montana Code Annotated § 27-2-102(3).
   • No claim-type-specific sub-rule was found here to shorten the period—so this 3-year rule is treated as the default unless your process overrides it based on a different, applicable basis.

How to isolate the variable

To find what’s driving the difference, use a structured comparison. Think of it like debugging:

• Purchase price / contract price

• Loan amount (principal)

• Down payment

• Recording-related fees (and whether a county-specific fee set is being applied)

• Title/escrow items

• Any vendor service fees you entered manually

• Pick one approach and keep it consistent:

  • credits as negative numbers, or
  • credits in a dedicated credit field (if your workflow uses one)

• The goal is consistency, not a particular convention.

• If one run is based on an estimate and the other on a settlement statement, rounding timing often differs.

• Also compare any “per unit / per $1,000” style fees for when rounding occurs.

• If one run uses a timeline window tied to the 3-year general SOL, confirm the other run isn’t using a different window or override.

• Montana’s default framework referenced here is 3 years under Mont. Code Ann. § 27-2-102(3), and no claim-type-specific sub-rule was found to change that default.

A practical 3-step method:

1. Run DocketMath with Run A using your best “full estimate” inputs.
2. Re-run with Run B, changing only one category (e.g., recording fees, credits, or a specific service fee).
3. Compare totals. If the difference largely disappears after one change, you’ve likely found the driver.

If you want a consistent starting point, use the DocketMath calculator: /tools/closing-cost.

Next steps

After you isolate the variable, you can make your results more consistent without changing the underlying math.

1. Lock an input schema

   • Always enter the same categories (even if some are $0).
   • Keep the meaning consistent (cost lines vs. credit lines).

2. Document where each line item came from

   • For each fee, note whether it came from:

     • a lender estimate,
     • a title/escrow estimate,
     • or a settlement statement.
   • This often explains rounding and fee-basis differences.

3. Use Montana’s default SOL framework as a baseline assumption

   • Montana’s general SOL period is 3 years under Mont. Code Ann. § 27-2-102(3).
   • This is the default described here because no claim-type-specific sub-rule was found in the materials provided.
   • If your workflow includes timing-dependent inclusion rules, align both runs to the same default assumption.

4. Re-run after changes and confirm directionality

   • If you swap credits handling, confirm whether the total moves in the expected direction before relying on it.

Gentle note: This is guidance for debugging calculator inputs, not legal advice. For legal questions about SOL or claim timing, consult a qualified attorney.
