Who this property is for
The same property is a great buy for one investor and a trap for another. Here's the honest read.
1031 / high-equity buyer
~$123.5K
Year-1 tax shield
Buying with cash or low leverage removes the debt-coverage problem entirely, so the thesis rests on appreciation plus a large first-year write-off. At roughly 25% of purchase price, the shield is substantial enough to carry the deal on its own.
Price-disciplined buyer
$399.9K
Break-even purchase price
Break-even is ~20% below the Zestimate, a discount sellers in Marathon rarely accept. Treat the number as a walk-away line rather than an opening offer.
DSCR cash-flow buyer
0.80
DSCR at asking
At asking price the property doesn't cover its own debt service, so it won't qualify for DSCR financing as modeled. If you need cash flow from day one, look at a mid-term-rental fallback or a different Marathon submarket.
For a buyer who materially participates and qualifies for the STR tax treatment.
$123.5K
Estimated first-year deduction · range $102.5K–$140.8K
Why this matters here
At a marginal bracket, this deduction can be worth $37.9K–$52.1K in estimated federal tax saved.
This only applies if you meet the IRS material-participation tests for short-term rentals and are not using a full-service property manager.
Estimate, subject to CPA review. Cost-segregation percentages shown here are illustrative and depend on an actual study of the property.
Some states do not conform to federal bonus depreciation, so your state may not allow the same first-year treatment shown above.
Chalet can introduce a cost-segregation partner — this is not tax, legal, or financial advice.

Projection, not a promise.
Assumes 5.0% annual appreciation, 1.5% rent growth (operating costs held flat), and that the property qualifies for short-term-rental tax treatment. The year-1 depreciation shield depends on a real cost-segregation study and your tax situation — consult a CPA.
Appreciation is the dominant driver of this return. When cash flow is negative, the deal depends on the property gaining value — it is not paying for itself from income.
Appreciation, rent growth, and financing rates are editable under Edit financials.
STR deals turn on local rules and demand that a generalist agent misses. Chalet matches you with a vetted Marathon agent who knows which properties actually cash flow — and which to avoid.
