Confidence comes from
understanding the assumptions.

Rental Resilience is an education-first prototype for evaluating U.S. residential rentals. Its purpose is to help you ask better questions, document evidence and understand the consequences of a deal underperforming.

A good outcome can be passing.

We support short-term and long-term strategies equally. We don’t assign a “safe investment” score or treat a purchase as the desired outcome. Learning that you need better evidence—or that a property does not fit your goals—is useful progress.

What the numbers mean

NOI is effective operating income less operating expenses, before debt service, depreciation and capital expenditures. Cash flow subtracts loan principal and interest and planned replacement funding. Cap rate divides NOI by purchase price. Cash-on-cash divides cash flow after replacement funding by down payment, closing costs, setup and initial reserve.

Monthly reserve balances include actual modeled cash inflows and outflows. Planned replacement transfers remain inside the consolidated reserve; actual repairs reduce it. A fixed-rate amortizing loan is held constant through income and expense shocks.

Model boundaries

All examples are fictional. Stress presets are editable assumptions, not forecasts, probabilities or guaranteed loss limits. The STR seasonal curve is illustrative and available nights are distributed evenly. LTR income losses are smoothed across twelve months. Intramonth timing, appreciation, income taxes, sale proceeds, refinancing, interest-only loans and balloon debt are outside this version.

STR room revenue excludes cleaning charges and lodging taxes. The per-night cost input should capture any net cleaning cost after guest charges. Platform, management and maintenance percentages are entered separately, then applied to room revenue. Annual fixed expenses and replacement budgets are itemized separately for STR and LTR. Actual contracts may require a more detailed treatment.

Editorial standards

Prepared as a project prototype for Alex. Research and copy were developed with AI assistance; specialist legal, tax and real-estate review has not been completed. General sources were checked October 4, 2026. For rules, prioritize official jurisdiction-specific sources and property documents. For costs, seek current written quotes; for revenue, inspect the comparables and assumptions.

Core lessons link to their sources. This site provides general education rather than personalized investment, legal or tax advice. There are no ads, sponsored rankings or affiliate links in this prototype.

Your data stays with you

Your progress, assumptions and notes are saved in this browser on this device. Fictional examples and your own evaluation are stored separately. Feedback is different: submitting the feedback form sends only the fields on that form to the site owner for review. Your evaluation is never attached automatically. They do not sync across devices. Export a text summary or print a PDF to retain a copy. Clearing browser storage removes local progress.
