AVM vs. Appraisal vs. BPO: Which Home Value Actually Counts?

Three different professionals-slash-algorithms can put three different numbers on your house on the same day. When you're trying to cancel PMI, only one of them is official, but the other two are how you avoid wasting money finding out. Here's the hierarchy.

AVM: the instant estimate

An automated valuation model is an algorithm's read on your home: recent nearby sales, tax records, square footage, market trends. Zillow's Zestimate is one; so is the estimate in our checker. Free (or cheap), instant, and honest AVMs come with a range, not a single number, because in a typical market they land within a few percent of eventual sale prices for typical homes, and further off for unusual ones.

What it's for: strategy. An AVM tells you whether the current-value path is worth pursuing before you spend anything. What it's not: acceptable to your servicer. No servicer cancels PMI off a Zestimate.

BPO: the drive-by professional

A broker price opinion is a real estate agent's valuation, often exterior-only, backed by comps. Cheaper than an appraisal (commonly $100–$300) and frequently what servicers order for current-value PMI reviews because it's cheap for everyone.

What it's for: whatever your servicer says it's for. If they accept a BPO, that's good news: lower cost to you for the same outcome.

Appraisal: the full inspection

A licensed appraiser, usually inside and out, full report. Typically $400–$600+. The most defensible number of the three, and what some servicers insist on for current-value cancellations.

The critical rule: an appraisal you commission on your own generally won't be accepted; the servicer orders it through their process, even though you pay. Ask before you spend a dollar.

The strategy, in one flow

1. AVM first (free): compute balance ÷ AVM. If your estimated LTV clears the current-value threshold with a comfortable margin (say, 72% against a 75% bar), proceed. If you're at 74.8%, understand you're flipping a coin on a $500 valuation.
2. Ask the servicer which instrument they use (BPO vs appraisal), the cost, and the threshold for your loan. Their answer is the only one that counts.
3. Order through them. If the official number clears the bar: PMI ends. If it comes in low: you're out the fee, nothing else changes, and you can retry after more appreciation or paydown.

The AVM's whole job is making sure step 3 is a formality, not a gamble.
