KEYS RV/MOBILE HOME CONDOMINIUM
Homes for Sale in Marathon, FL
True comps, carrying-cost math, and listings before the portals.

Keys RV/Mobile Home Condominium sits in Marathon, Monroe County — the heart of the Middle Keys — where land scarcity and the cost of coastal living set a hard floor under values. The median sale price of $245,000 reflects a format that is affordable relative to the broader Florida Keys market, but the 263% appreciation since 2012 makes clear this segment has moved sharply over the past decade-plus. Buyers expecting a bargain simply because the structure is a mobile home or RV unit will need to recalibrate to Keys economics.
With a median days on market of 96 and only 5 closings in the measured window, this is a thin, slow-moving market. That combination signals limited turnover and a buyer pool that takes its time — or that listings sometimes sit waiting for a very specific buyer. Sellers should price with precision from day one; overpricing in a low-volume community tends to stall badly. Buyers have the luxury of deliberation, but meaningful inventory is scarce.
The 60-Second Overview
KEYS RV/MOBILE HOME CONDOMINIUM market snapshot (as of July 27, 2026): the median sale price is about $245K, and a median 96 days on market for closed sales.
Keys RV/Mobile Home Condominium offers a condominium-ownership structure in one of Florida's most land-constrained coastal counties, giving owners a deeded stake in a Marathon Keys address at a price point that sits well below single-family waterfront product — though prices here have climbed substantially over the past decade-plus.
Who KEYS RV/MOBILE HOME CONDOMINIUM is best for.
Best for
- A buyer with a specific budget targeting a deeded ownership interest in the Florida Keys who accepts a non-traditional structure type in exchange for that address.
- A seasonal or part-time Keys user who wants a low-overhead owned base in Marathon rather than paying for lodging or renting long-term.
- A patient investor or buyer who has a long time horizon and is not dependent on quick resale — thin volume means exit timing is unpredictable.
Probably not for
- A buyer who needs conventional mortgage financing without researching lender restrictions on mobile home or RV condominium structures — this format can limit financing options significantly.
- Someone prioritizing community amenities as part of daily life — none were identified in current MLS listings.
- A buyer who may need to sell within a short time frame, given the 96-day median days on market and very limited annual transaction volume.

The KEYS RV/MOBILE HOME CONDOMINIUM buying strategy.
If we were buying in KEYS RV/MOBILE HOME CONDOMINIUM today, this is the order of operations we would run for our clients.
Underwrite the condition first. Price the roof, HVAC, and systems honestly before judging any list price; condition swings value here more than square footage alone.
Match the home to real comps. Recent sales of similar condition and lot, not the asking price, tell you what a home is worth.
Move deliberately, not desperately. Neither side has a decisive edge, so a well-prepared, fairly-priced offer wins without overpaying.
Line up financing and inspection early. A pre-approval and an inspection plan let you act fast and negotiate from evidence.
Keep an agent in your corner. The listing agent works for the seller; we represent you and prepare a hand-built valuation before any offer in KEYS RV/MOBILE HOME CONDOMINIUM.
What the numbers actually tell you
The 263% price gain since 2012 is the defining fact here. It tells you that demand for any ownership foothold in the Florida Keys — regardless of structure type — has been relentless. Monroe County's strict limits on new residential development mean supply cannot simply expand to meet demand, and that dynamic has lifted this segment alongside every other. The $245,000 median is the outcome of that pressure, not a sign of weakness in the product.
The 96-day median days on market deserves a plain interpretation: this community does not trade quickly. Volume is low — five closings in the snapshot window — so each transaction carries outsized weight in the data, and individual unit condition, location within the community, or lease-versus-ownership nuances can explain wide price variation from sale to sale. No community amenities were identified in current MLS listings, which means buyers should evaluate the lifestyle value based on the Marathon location itself — proximity to boating, fishing, and the character of the Middle Keys — rather than on-site amenity packages.
The location and the amenities are priced into every listing in KEYS RV/MOBILE HOME CONDOMINIUM. The deal is won or lost on condition, the comps, and the renovation math.
Why work with Momentum here
Low-volume markets punish buyers and sellers who rely on thin comps. With only a handful of closings in the data window, a single outlier transaction can distort a valuation in either direction. Momentum's analysts work from primary MLS data and understand how to weight sparse comparable sets — critical in a community where the next sale may not come quickly and mispricing has real consequences. We will tell you plainly what the data supports and where it runs out.
