Rental operations
Evaluate whether recurring rental income covers vacancy, operating expenses, debt service, and a cash-flow target.
Where to start: Start with Rental Property ROI for the full scenario; use NOI to isolate operations, Break-Even to solve required rent or occupancy, and Prorated Rent for one partial month.
Rental Property: Cash Flow & ROI
Model financing, operating assumptions, cash flow, NOI, returns, and break-even points.
Open calculator →NOI
Audit effective gross income, itemized operating expenses, NOI, and expense sensitivity.
Open calculator →Break-Even Rent & Occupancy
Solve required scheduled rent and collected occupancy from monthly costs and a cash-flow target.
Open calculator →Prorated Rent
Compare one partial-month rent period under actual-days, 30-day, annual/365, and lease-defined daily-rate conventions.
Open calculator →Financing and debt
Test how property value, NOI, payment structure, and coverage constraints affect a modeled loan.
Where to start: Start with Maximum Loan Amount when sizing across constraints; use Mortgage Payment for the payment path, LTV for the value basis, Debt Yield for NOI versus principal, and DSCR for income versus debt service.
Debt Yield
Compare annual NOI with current or proposed debt and reverse-solve an editable target.
Open calculator →Loan-to-Value (LTV)
Compare one modeled first-lien loan with an explicit purchase-price, current-value, or after-repair-value basis.
Open calculator →Maximum Loan Amount
Size one modeled loan under simultaneous LTV, Debt Yield, and DSCR constraints.
Open calculator →Mortgage Payment & Amortization
Model amortizing or interest-only payments, fees, balances, and rate sensitivity.
Open calculator →DSCR Loan
Compare NOI with debt service, an editable target, and required income.
Open calculator →Returns and valuation
Compare property-level income yield with the cash return created by financing and upfront investment.
Where to start: Start with Cap Rate for an unlevered property yield and valuation view; use Cash-on-Cash Return when financing and total upfront cash belong in the denominator.
Renovation and exit
Reconcile transaction cash and model the complete cost and return of a renovation-and-resale project.
Where to start: Start with Closing Costs for one buyer or seller settlement; use House Flip / Fix-and-Flip for the full acquisition, rehab, holding, financing, and resale timeline.
