Inputs you will need

Run this scenario in DocketMath using the Closing Cost calculator.

To estimate closing costs in Illinois with DocketMath (tool: closing-cost), gather the inputs below first. You’ll enter them into the calculator so it can produce an estimated total—and so you can see how the estimate changes when you update values.

Use this checklist as your “closing-cost input” sheet:

Timing and totals depend on the closing package

Closing costs don’t always move through the same “bucket.” Different transactions package fees differently—some items are paid at closing, while others are collected for escrow and paid later as bills come due.

When you enter inputs, DocketMath’s output will generally reflect whether an item is treated as:

Paid at closing (impacts your estimated cash required up front), or
Collected for later (impacts your total out-of-pocket at closing, but may shift how it appears versus standard “fee-only” thinking)

Pitfall: Don’t mix “annual” and “monthly” numbers. For example, if your insurance quote is $1,800/year, use it consistently with how your closing-cost assumptions interpret insurance for escrow/impound estimates.

Illinois timing context (general, not claim-specific)

Illinois has a general statute of limitations (SOL) period of 5 years: 720 ILCS 5/3-6. No claim-type-specific sub-rule was found in the provided rule set, so the default 5-year period applies for general timing questions referenced in documentation workflows.

Gentle note: This SOL context is about general planning and record/timeline awareness, not about changing how the closing-cost math works.

Where to find each input

Most of the numbers you need come from lender documents, the purchase agreement, and any provider quotes. Here’s a practical “where to get it” map, plus what to extract.

Input	Where to find it	What to extract
Purchase price	Purchase agreement / contract	Exact contract amount (dollars)
Loan amount	Loan Estimate (LE) or Closing Disclosure (CD)	The “Loan Amount” field
Down payment	Purchase agreement and lender docs	Cash down paid at closing
Property location (county)	Address / legal description	County for localized fee assumptions
Escrow/impounds	Loan Estimate or Closing Disclosure	Total escrow collected at closing
Homeowner’s insurance estimate	Insurance quote / binder	Annual premium used to estimate monthly escrow
Prepaid interest	Loan Estimate / Closing Disclosure	Interest collected from closing to end of month
Title services	Title company estimate	Title/settlement service fees (estimate or actual)
Attorney fee estimate	Lender/provider disclosures or vendor estimate	Any fixed settlement/attorney fee
Recording fees estimate	Closing disclosure or county fee sheet	Recording line(s) or totals
Credits / concessions	Seller credit terms / lender credit terms	Dollar amounts that reduce net cash
Known concessions	Negotiated terms	Any concession amount you’ve agreed to

Use the newest lender document (LE vs. CD)

If you have both a Loan Estimate (early stage) and a Closing Disclosure (near closing), prefer the most current one for fee-related values. If the amounts differ, DocketMath will reflect the numbers you enter—so your estimate will track the document you used.

Helpful workflow: If you’re within days of closing, use the Closing Disclosure numbers for the most realistic estimate.

Run it

Open DocketMath → closing-cost:
/tools/closing-cost
Enter your values in the calculator fields:
- Start with purchase price and loan amount (or down payment, if you’re using a simplified input approach).
- Add escrow/impounds and any prepaid items (like prepaid interest) if you have estimates.
- Include credits as an offset if the calculator supports credit/offset inputs (follow the calculator’s input format).
Review the output breakdown:
- Your estimated cash to close / estimated total upfront amount (wording may vary by calculator configuration)
- Line-item categories (often separated into fees, prepaid/escrow, and credits/offsets)
Run “what-if” checks (quick sanity testing):
- Update the down payment: a higher down payment usually lowers loan amount and can shift lender-related estimates.
- Update escrow/insurance assumptions: raising the annual insurance estimate can increase monthly escrow assumptions, which can increase amounts collected at closing.
- Add a known credit: credits generally reduce net out-of-pocket at closing.

How outputs change when you tweak inputs

Use this cause-and-effect guide while entering numbers:

Higher purchase price → often increases fee bases tied to the transaction amount.
Higher loan amount → can increase lender-related estimates and may affect escrow collection assumptions.
Higher insurance estimate → may increase escrow collections if your inputs are used to estimate monthly impounds.
More credits/concessions → typically lowers net cash required at closing.

Reminder: If you leave escrow/impounds blank, the calculator estimate may be accurate for “fees-only,” but it can understate cash to close, because escrow collection is often a significant upfront component.

Gentle disclaimer: Closing costs can vary based on deal specifics, lender practices, and final settlement statements. Use DocketMath as an estimate tool, not legal or financial advice.
