Rental property analysis depends on getting operating expenses right, and that's where most first deals go wrong. Vacancy, maintenance, capital expenditure reserves, and property management typically consume 35–50% of gross rent. A deal that pencils on rent minus mortgage almost always loses money in practice.
Which metric matters depends on how you're financing. Cap rate ignores financing entirely and compares properties on their own merits. Cash-on-cash measures return on the money you actually put in. DSCR is what the lender cares about, since it determines whether the deal qualifies at all.

Core return metrics
Cap rate compares properties independent of financing. Cash-on-cash reflects leverage and shows return on your actual cash in. Yield measures rent against price.
Financing and qualification
DSCR loans qualify on the property's income rather than yours. Each lender sets its own minimum ratio; interest-only structures raise the ratio by removing principal from the debt service figure.
Strategy-specific
BRRRR depends on the refinance appraisal supporting your rehab spend. House hacking offsets your own housing cost with tenant rent. Flips live or die on accurate rehab budgets and holding costs.
