What moves the sale price in Marathon beyond the medians

New construction was 8% of sales, which sets the ceiling on what resale buyers will pay for a comparable resale. Sellers have been closing at 90.3% of original asking, so the list price is a negotiation opener, not the number. Zillow’s ZIP metrics put the city’s price-to-income ratio near 11.66 and five-year appreciation near +5.2%. Condition, lot, roof age, insurance quote and the specific street’s last three closings move an individual house well outside these ranges.

What is my house worth in Marathon?

Not a number this page can give you, and not one an automated model can either: every value above is a median of many Marathon sales, and the spread inside it is wide. A records-based valuation pulls the recorded closings on your street and in your community, adjusts for size, condition, lot and what your home has that the comps do not, and comes back as a written range with a net sheet showing what you would clear at each price after commissions, Florida doc stamps, title and payoff. Momentum Realty does that for Marathon owners at no cost through the form below; the Messtimate gives a square-footage range in the meantime, and the seller net proceeds calculator runs the arithmetic on any price you are considering.
