What Is Your Home Really Worth?
Whether you’re considering selling, refinancing, tapping equity, or simply tracking your net worth, knowing your home’s current market value is essential. But determining an accurate value requires more than checking an online estimate—it requires understanding the methods available and their relative reliability.
Online Valuation Tools (AVMs)
Automated Valuation Models from sites like Zillow (Zestimate), Redfin, and Realtor.com use algorithms to estimate property values based on public data, recent sales, and property characteristics. These tools provide a quick starting point but have significant limitations. Their accuracy varies widely—median error rates range from 3% to 7% nationally, and can be much higher in areas with fewer comparable sales or unique properties. They may not account for interior condition, renovations, views, or other value-affecting factors that aren’t in public records.
Use online estimates as a rough starting point, not a definitive value. The difference between an AVM estimate and actual market value on a $400,000 home could easily be $20,000 to $40,000 or more.
Comparative Market Analysis (CMA)
A CMA prepared by a real estate agent is the most common method for determining market value. The agent analyzes recently sold comparable properties (comps)—homes similar to yours in size, age, condition, and location that sold within the past three to six months. Adjustments are made for differences in features, upgrades, lot size, and other characteristics.
A well-prepared CMA is typically more accurate than online tools because the agent can account for property condition, local market nuances, pending sales not yet in public records, and qualitative factors like views or street appeal. Most agents provide CMAs at no cost, making this an accessible and reliable valuation method. Request a free CMA from a NearbyRealtors agent to learn what your home is worth.
Professional Appraisal
A licensed appraiser provides the most formal and detailed valuation. Appraisals are required for mortgage transactions but can also be ordered independently. The appraiser physically inspects the property, researches comparable sales, and produces a detailed report with a specific value opinion. Appraisals cost $400 to $700 but provide the highest level of professional certainty. Understanding appraisals is also important for buyers—our appraisal guide explains the buyer’s perspective.
Factors That Affect Your Home’s Value
Location is the dominant factor—school district, neighborhood desirability, proximity to amenities, and commute options heavily influence value. Size and layout matter, including square footage, bedroom and bathroom count, and functional floor plan. Condition and updates significantly affect value—a well-maintained home with modern updates commands a premium over a similar home with deferred maintenance. Market conditions including local supply and demand, interest rates, and economic factors create the environment in which transactions occur. Lot characteristics like size, topography, views, privacy, and outdoor features add or subtract value.
When to Get a Valuation
Regular value awareness is useful, but formal valuations are most important when you’re considering selling and need to set a listing price. When refinancing, as the lender will require an appraisal. When exploring a home equity loan or HELOC and need to know available equity. When appealing property tax assessments. When reviewing insurance coverage to ensure adequate protection.
