HYPOTHETICAL REFINANCE CHECK

Enter the target rate and actual closing-cost estimate.

The balance and remaining term are held equal for comparison. A real refinance can reset the term, change escrow/insurance and add financed costs.

03 · WHAT STILL NEEDS EVIDENCE

Do not let a clean total hide an unanswered risk.

Insurance evidenceBuyer tax evidenceHOA documentsRoof installedHVAC installed

Insurance uncertainty

Get a current address quote and review deductible, roof settlement, exclusions, flood and wind terms.

MISSING

Tax reassessment

Do not automatically budget from the seller's current tax bill. Ask the assessor how purchase affects taxable value.

MISSING

Systems and condition

Roof planning age: 14 years. HVAC planning age: 11 years. Age alone does not prove remaining life; request condition evidence.

PLANNING

HOA special assessment

No HOA amount entered. Confirm that the property has no mandatory association or community fee.

VERIFY

Climate and coverage

Use the exact address—not the ZIP alone—to check FEMA flood mapping and ask the carrier about flood, wind, wildfire and water exclusions.

ADDRESS CHECK

Confidence: Planning-only until the exact loan, buyer tax treatment, insurance scope, HOA file and property condition are documented.

WHAT THE CALCULATOR COUNTS

One formula, with every assumption left open.

True monthly homeownership cost equals principal and interest plus property tax, home insurance, HOA, PMI, utilities, routine maintenance and a major-replacement reserve. Cash to buy and five-year non-equity cost are shown separately so a down payment is not mislabeled as spending.

MONTHLY

Mortgage + the bills around it

Change every recurring line. ZIP lookup supplies broad state planning inputs only; the documents for the exact home control.

UP FRONT

Cash needed before and after closing

Down payment, closing costs, inspection, moving, setup and retained emergency cash stay visible instead of being folded into one vague total.

FIVE YEARS

Non-equity cost, principal separate

Interest and entered ownership costs are counted. Estimated principal paid is reported separately; appreciation and resale are not forecast.

ILLUSTRATIVE STARTING CASE

A $500,000 home with 20% down

The page starts with a hypothetical 6.5% 30-year loan, $6,250 annual tax, $2,400 annual insurance, $350 monthly utilities, a 1% maintenance allowance and a $250 monthly replacement reserve. Replace every number before relying on the result.

Mortgage principal & interest: $2,528/mo
True monthly cost: $4,266/mo
Cash to buy, including retained reserve: $135,397
Five-year non-equity cost: $252,990

SOURCES AND LIMITS

Every estimate has a job—and a boundary.

ZIP lookup localizes state tax, insurance and electricity planning inputs. Your entries remain the controlling assumptions. HomeCostGrid does not store an address on this page.

Loan and closing evidence

Compare the result with the lender's current Loan Estimate and Closing Disclosure.

QUICK ANSWERS

Use the number, then verify the home.

What does a true cost of homeownership calculator include?

This calculator includes mortgage principal and interest, property tax, home insurance, HOA, PMI, utilities, routine maintenance and a separate major-replacement reserve. It also keeps closing, moving, setup and emergency-reserve cash visible.

Is true monthly cost the same as a mortgage payment?

No. It adds editable planning amounts for property tax, insurance, HOA, PMI, utilities, routine maintenance and major replacements to principal and interest.

Does the five-year cost include home equity?

The result separates estimated principal paid from non-equity costs. It does not predict appreciation, resale proceeds or selling costs.

Is this a lender approval or an insurance quote?

No. It is a planning model. Confirm lending terms with Loan Estimates and confirm property-specific coverage and premiums with current written quotes.

How often should I update the calculation?

Update it whenever the price, loan terms, tax treatment, insurance quote, HOA documents, utility evidence, inspection findings or system condition changes.
