A home valuation determines the current market value of a residential property. It is crucial for real estate transactions, preventing excessive borrowing and financial losses. When getting a mortgage, the home acts as collateral. If the borrower defaults, the lender may sell the property to recover funds. A thorough home valuation safeguards the lender's ability to recover costs if the mortgage is not fully repaid. 

The value of your home is calculated using a combination of factors including its location, age, size, condition, any improvements or renovations made, and recent sale prices of comparable homes in the neighborhood. It also factors in current market trends and local market conditions. The valuation tool is dynamic and can be influenced by data such as inventory trends, interest rates, and current buyer sentiment.

Online home valuations provide a good starting point and offer a general estimate of your property's worth. However, they may not factor in recent renovations, unique features, historical value, architectural significance, and subjective market perception that could impact your home's actual market value. For the most accurate assessment, consider scheduling an in-person appraisal.
