- Zestimate and online estimates can be off by 5–15% or more — don’t rely on them alone
- A Comparative Market Analysis (CMA) from a local agent is the most accurate estimate
- Your home’s value depends on condition, upgrades, location, and current market demand
- Overpricing costs you money — homes that sit get stigmatized and sell for less
What Will My House Actually Sell For? The Honest Answer
This is the first question every seller asks — and unfortunately, the internet often gives the wrong answer. Zestimates, AVM tools, and tax assessment values are starting points at best. Here’s how home value is actually determined, and how to get a number you can actually rely on.
How Home Value Is Calculated: The CMA
Real estate agents use a Comparative Market Analysis (CMA) to estimate your home’s value. A CMA compares your home to recently sold, currently active, and recently expired listings with similar characteristics:
- Location: Same neighborhood, ideally within 0.5–1 mile
- Size: Square footage within 10–15% of your home
- Bedroom/bath count: Same or adjacent configuration
- Condition and upgrades: Remodeled kitchen vs. original; new HVAC vs. 20-year-old system
- Lot size: Especially relevant for single-family homes
- Age and school district
A skilled agent then adjusts the comps up or down based on differences from your property, arriving at a supportable estimated value range.
What Factors Increase Your Home’s Value?
- Updated kitchen (especially counters, cabinets, and appliances)
- Updated bathrooms
- New flooring (hardwood or luxury vinyl plank)
- Fresh interior/exterior paint
- New roof, HVAC, or water heater (buyers value peace of mind)
- Additional square footage (finished garage, ADU, converted space)
- Strong school district and low-crime neighborhood
- Curb appeal and well-maintained landscaping
What Decreases Your Home’s Value?
- Deferred maintenance (peeling paint, outdated systems, roof issues)
- Functional obsolescence (awkward floor plan, bedroom/bath imbalance)
- Location factors (proximity to freeway, commercial property, high-voltage lines)
- Outdated finishes that most buyers would immediately want to replace
- Foundation or structural issues (even disclosed ones)
Online Home Value Estimates — How Accurate Are They?
Zillow’s Zestimate has a median error rate of 2–7% nationally — but in less-active markets or unique properties, that error can exceed 10–15%. For a $600,000 home, a 10% error is $60,000. Never list based on a Zestimate alone. Use it as a ballpark only.
How to Get the Most Accurate Home Value Estimate
- Request a free CMA from a local agent — this is what I provide at no cost, no obligation
- Get a pre-listing appraisal — a licensed appraiser’s opinion is more defensible than an agent CMA but costs $400–$600
- Check active competing listings — what are homes like yours listed at right now? That’s your competition.
Frequently Asked Questions
How accurate is Zillow’s Zestimate?
Zillow reports a median error rate of 2–7%, but the actual error on individual homes can be much larger — especially for unique properties or markets with limited recent sales. Use it as a rough reference only, not for listing decisions.
How do I find out what my house is worth for free?
Request a free Comparative Market Analysis (CMA) from a local real estate agent. This is the most accurate free home value estimate you can get, and experienced agents provide it with no obligation.
What is a CMA in real estate?
A Comparative Market Analysis (CMA) is a report prepared by a real estate agent that estimates your home’s market value based on recent sales of comparable properties in your area. It accounts for size, condition, location, and current market conditions.
How much will I profit from selling my house?
Your net profit = Sale price minus mortgage payoff, agent commission (4–6%), closing costs (1–3%), and any repairs or credits. Request a seller’s net sheet from your agent before listing — it shows your estimated proceeds at different sale price scenarios.
Does my home need to appraise for the sale price?
If the buyer is using financing, yes — the lender will require an appraisal. If the home appraises below the sale price, either the buyer must make up the difference in cash, or the parties renegotiate. Your agent will help you navigate low appraisals.
