For a home equity line of credit on a Montclair house, the lender decides what valuation it needs and usually orders it: an automated valuation, an evaluation, an exterior or desktop report, or a full interior appraisal. The choice depends on the lender's own policy and the federal rules it is under, and the value it accepts is one input to the credit limit, beside the existing mortgage balance and the borrower's ability to repay. A homeowner-ordered appraisal helps only if the lender agrees in advance to accept it.
This article is part of the PMI removal and home equity appraisals section. Its pillar, PMI removal appraisals: what the servicer reviews, covers the mortgage insurance side.
What a HELOC is, and why the lender values the house
The Consumer Financial Protection Bureau describes a HELOC as an "open-end" line of credit that lets you borrow repeatedly against your home equity, equity being the home's value minus what you owe on the mortgage. The house secures the line, and the CFPB warns that a borrower who falls behind could lose the home.
The CFPB's booklet on home equity lines, prepared by the Federal Reserve Board and updated by the CFPB in January 2014, explains that many lenders set the credit limit by taking a percentage of the home's appraised value and subtracting the balance owed on the existing mortgage, and then also weigh income, debts and credit history. The percentage is the lender's; ask the lender, not a calculator. The same booklet lists an appraisal fee among the costs of opening a line.
What the lender may order
A lender is the client for the valuation it orders, and its policy sets the form. The range runs from no inspection to a full one.
- An automated valuation model. An automated valuation model, or AVM, is a statistical estimate produced from public records and nearby sales. It does not see the house, and it is not an appraisal.
- An evaluation. Federal banking rules exempt some transactions from the appraisal requirement. The Office of the Comptroller of the Currency's rule at 12 CFR 34.43, for national banks, exempts residential transactions at or below a stated transaction value and certain existing extensions of credit, and for those requires "an appropriate evaluation of real property collateral that is consistent with safe and sound banking practices." An evaluation is not an appraisal under that rule.
- An exterior-only or desktop appraisal. An appraiser's opinion of value developed without an interior inspection, from the street or from data; exterior-only and desktop assignments explains what each relies on.
- A full appraisal with an interior inspection. Gross living area measured on site, condition rated from what is seen, and closed comparable sales analyzed.
A broker price opinion, a value estimate prepared by a real estate broker or agent, and an agent's comparative market analysis are not appraisals either. Which of these a lender uses is its decision. The same appraisal standard applies to every appraisal, but a HELOC lender's form and scope can differ from a first-mortgage refinance; refinance and mortgage appraisals covers the refinance side.
Why a Montclair house is read carefully
Montclair, ZIP code 91763, is in San Bernardino County, and its western boundary is Mills Avenue, the county line with Claremont and Pomona. The Montclair area page has the full local picture. The points that come up on an equity valuation:
- Postwar tracts that differ by additions. Most Montclair houses are single-story postwar and later tract homes on regular lots, built as the former Monte Vista orchard tracts filled in. They differ mainly in additions, garage conversions, lot size and condition. An automated estimate reads the recorded square footage; an interior inspection finds what was added and whether it was permitted.
- Converted garages. A converted garage counted as permitted living area is a recurring reviewer rejection here. The permit status decides how that space is treated.
- Sales across Mills Avenue. A similar postwar house in Claremont or Pomona sits in a different county, with a different assessor, school districts and buyer pool. Such a sale can be valid evidence only with the location difference explained; what the county line does to comparable sales sets out why.
- The I-10. The San Bernardino Freeway crosses the north of the city. North of it the tracts meet the Claremont and Upland lines; south of it they run toward Pomona and Chino. Sales from the other side of the freeway are a question when closer tract sales exist.
- Small income property near the Transit Center and Montclair Place. Duplexes, small buildings and houses divided into units need legal unit count checked against permits and records, and a duplex is not compared with single-family sales. A lender's HELOC program may not cover them at all; ask first.
- Condominiums and townhomes. Compared within similar projects, with HOA documents reviewed.
If the line is frozen or reduced
The CFPB says that if a home's value drops significantly, the lender may stop allowing new draws. Its booklet's advice for a borrower who wants the line restored is lender-first: "If your lender suggests getting a new appraisal, be sure you discuss appraisal firms in advance so that you know they will accept the new appraisal as valid." The same rule holds when opening a line. Ask the lender, in writing, whether it accepts a homeowner-ordered appraisal, from whom, on what form, naming whom as intended user, the party entitled to rely on the report, and with how recent an effective date, the date the opinion of value applies to.
A HELOC and mortgage insurance on the same house
If the first mortgage carries private mortgage insurance, a home equity line matters to any cancellation request. The Homeowners Protection Act, at 12 U.S.C. 4902(a)(4)(B), lets the holder require a certification that the borrower's equity is not encumbered by a subordinate lien, and a HELOC is a subordinate lien. Automatic vs. requested PMI cancellation explains which route that condition belongs to.
What the appraisal does and does not do
When a lender accepts it, an appraisal documents current market value, the opinion of market value as of a recent effective date, with the comparables and adjustments shown so the lender can follow them. It does not set the credit limit or approve the line. The appraiser is independent of every party, including the homeowner who pays. The fee is set by the scope of the assignment and quoted before work begins, and it does not depend on the value. The inspection runs 30 to 60 minutes for a standard single-family home, longer for multi-family or homes with additions.

Ask the lender what valuation it uses first. If it accepts a homeowner-ordered appraisal, send its requirements and the address through the PMI removal and home equity appraisal page, or call (909) 324-6122.

Frequently asked questions
Does a HELOC in Montclair need a full appraisal?
Not always. The lender decides. Depending on its policy and the federal rules it is under, it may use an automated valuation model, an evaluation, an exterior-only or desktop report, or a full appraisal with an interior inspection. The OCC's rule at 12 CFR 34.43 requires an appropriate evaluation, rather than an appraisal, for certain exempt residential transactions.
Can I order my own appraisal for a HELOC?
Only if the lender agrees in advance to accept it. The CFPB's home equity booklet advises borrowers to discuss appraisal firms with the lender first so they know it will accept a new appraisal as valid. Ask which appraisers, which form and which intended user the lender requires.
How does the appraised value relate to the credit limit?
It is one input. The CFPB's booklet explains that many lenders take a percentage of the appraised value and subtract the existing mortgage balance, then also weigh income, debts and credit history. The percentage and the decision belong to the lender; an appraisal does not set or approve the line.
Why do sales across Mills Avenue need explaining in a Montclair report?
Mills Avenue is the county line. A similar house in Claremont or Pomona is in Los Angeles County, with a different assessor, school districts and buyer pool. Such a sale can still be valid evidence, but the report must explain the location difference, and Montclair sales come first.
