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 Cash-Out Refinance for replacement-loan cash and payment reconciliation, Seller Financing for one purchase funded by cash down and a seller note, Commercial Loan for separate maturity and interest-only phases, Mortgage Payment for a fully amortizing payment path, LTV for the value basis, Debt Yield for NOI versus principal, and DSCR for income versus debt service.
Hard-Money and Bridge Loan
Estimate interest-only payments, upfront financing fees and original principal due at maturity for one fully funded fixed-rate loan.
Open calculator →Cash-Out Refinance
Reconcile proposed replacement-loan proceeds, debt payoff and costs, with new payments, interest, LTV and equity.
Open calculator →Seller Financing
Estimate one seller note’s payments, balloon principal, final maturity cash and purchase-payment totals.
Open calculator →Commercial Real-Estate Loan
Model fixed-rate payments, interest-only phases, balloon maturity, upfront fees and optional coverage.
Open calculator →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 GRM for a gross scheduled-rent screen and Cash-on-Cash Return when financing and total upfront cash belong in the denominator.
Cap Rate
Estimate NOI, property-level yield, implied value, and rent sensitivity.
Open calculator →Gross Rent Multiplier
Compare purchase price with annual scheduled rent and explore editable target inverses.
Open calculator →Cash-on-Cash Return
Compare annual pre-tax cash flow with the cash invested upfront.
Open calculator →Renovation and exit
Reconcile transaction cash and model the complete cost and return of a renovation-and-resale project.
