Glossary
Plain-language definitions — each linked to the guides where the term is used.
Foundations

US Nonresident Alien Income Tax Return — the federal return a non-resident files to report US-source income, including net rental income from US real estate once the property is treated as effectively connected.
- D-U-N-S Number
A free, unique nine-digit identifier issued by Dun & Bradstreet that anchors your business credit file and is required by many vendors and government agencies.
- EIN
Employer Identification Number — the federal tax ID issued by the IRS that identifies your business for tax and banking purposes, obtainable without an SSN.
- FIRPTA
Foreign Investment in Real Property Tax Act — the law that makes a buyer withhold a percentage of the sales price (typically 15%) when a foreign person sells US real estate, as a prepayment of the seller's US tax.
- Fundability
How complete, consistent, and legitimate your business looks to lenders and credit bureaus — matching entity details, real address, phone listing, and licenses determine whether you get approved.
- ITIN
Individual Taxpayer Identification Number — a personal tax ID issued by the IRS for individuals who are not eligible for a Social Security Number, used to file US tax returns and build credit.
- Net-30 Account
A vendor account that invoices you for goods or services and gives 30 days to pay — when the vendor reports payment history, these accounts become the building blocks of business credit.
- Registered Agent
The person or company designated to receive official legal mail and service of process on behalf of your LLC or corporation in its formation state — required by law.
Buy a Business
- Bolt-On Acquisition
A smaller company bought and merged into a larger business you already own — adding customers, capacity, or geography at lower cost and risk than building from scratch or buying a standalone platform.
- Buy Box
A buyer's explicit acquisition criteria — industry, size or revenue band, geography, and deal structure — used to filter opportunities fast and to tell your network exactly what you're looking for.
- Deal Intermediary
A trusted professional — a CPA, attorney, wealth manager, or banker — positioned to know when a business owner is ready to sell, and who can refer off-market deals before they ever reach a listing.
- EBITDA
Earnings Before Interest, Taxes, Depreciation, and Amortization — a standardized profitability metric used to value and compare mid-market and larger businesses.
- MUD Score
An informal gauge of how ready a seller is to do a fast or creative deal — Motivation, Urgency, and Distress. The higher the MUD, the more flexible the seller on price and terms.
- Quality of Earnings
A due-diligence analysis that verifies a business's reported earnings are real, recurring, and sustainable — separating owner-inflated SDE from what a buyer can actually expect.
- Reps & Warranties
The seller's written promises in a purchase agreement about the true state of the business — accurate financials, no undisclosed liabilities, clean title. If a rep turns out false, the buyer has a remedy: indemnity, or offset against a seller note.
- Roll-Up
An acquisition strategy that buys several small companies in the same industry and combines them into one larger entity — which is worth more per dollar of earnings and far easier to sell to a private-equity buyer.
- Sale-Leaseback
A transaction where a business sells an owned asset — usually real estate — and simultaneously leases it back, freeing capital for the core operating business or an acquisition.
- SDE
Seller's Discretionary Earnings — the total financial benefit an owner-operator extracts from a small business, used to value and price small-company acquisitions.
Creative Finance
- Balloon Payment
A large lump-sum payment of the remaining principal balance due at the end of a short-term note, common in seller-financed and commercial loans.
- Contract for Deed
An installment sale where the seller keeps legal title while the buyer takes possession and pays over time; title transfers only after the final payment. Also called a land contract or executory contract.
- Due-on-Sale Clause
A provision in most mortgage contracts giving the lender the right to demand full repayment if the property is transferred or sold.
- Hybrid Financing
A creative-finance purchase that layers two pieces of financing: the seller's existing mortgage taken subject-to (first position) plus a seller-carried note for their equity (second position).
- Lease Option
A lease combined with the option — but not the obligation — to buy the property at a set price within a set period. The buyer pays an option fee; part of the rent may credit toward the purchase.
- Novation
Replacing an existing contract or party with a new one by consent of everyone involved — the old obligation is extinguished, not merely handed off like an assignment.
- Promissory Note
A written, legally binding promise to repay a debt under specified terms — the core document in any seller-financed transaction.
- Sandwich Lease Option
A lease-option structure where an investor leases a property from the owner with an option to buy, then subleases it to a tenant-buyer at higher terms — profiting on the spread without owning the property.
- Seller Financing
A purchase structure where the seller acts as the lender, carrying a promissory note instead of requiring a lump-sum bank payoff.
- Subject-To
A property acquisition where the buyer takes title while the seller's existing mortgage stays in place — the loan is not paid off or assumed.
- Wraparound Mortgage
A seller-financed junior note that wraps around and includes the existing underlying loan, with the buyer making one payment to the seller who continues paying the first mortgage.
Real Estate / Cashflow
- BRRRR
Buy, Rehab, Rent, Refinance, Repeat — a real estate investment strategy that recycles capital through cash-out refinancing to build a portfolio with one initial pool of money.
- Cap Rate
Capitalization rate — a property's net operating income divided by its market value, used as a quick yield and valuation shorthand in commercial and multifamily real estate.
- Cash-on-Cash Return
The annual pre-tax cashflow a rental property generates divided by the total cash invested — the simplest measure of how hard your money is working.
- Gross Rent Multiplier (GRM)
A quick screening ratio — purchase price divided by annual gross rent — that lets investors compare rental properties for income efficiency before running a full cashflow analysis.
- Leasing / Tenant-Placement Fee
A one-time fee a property manager charges to find, screen, and place a new tenant — often 50-100% of one month's rent — making tenant turnover a significant cost.
- Maintenance & CapEx Reserve
Money set aside monthly for ongoing repairs and future capital expenses — the line item beginners most often omit, making deals look more profitable than they really are.
- Maintenance Markup
A percentage surcharge (often 10-15%) some property managers add on top of repair invoices for coordinating the work — a hidden cost that inflates the true operating expense.
- Master Lease
A lease in which one party rents an entire property — often with the right to sublease — commonly used by short-term rental operators and by owners seeking guaranteed rent from an operator.
- NOI (Net Operating Income)
A property's gross rental income minus operating expenses — the number that cap rate and DSCR are built on, calculated before debt service and capital expenditures.
- Property Management Fee
The recurring monthly charge a property manager collects — typically 8-10% of collected rent — for handling day-to-day operations, tenant communication, and rent collection.
- Rental Arbitrage
Leasing a property long-term and subleasing it short-term (e.g. Airbnb) or furnished mid-term — profiting from the spread between the fixed rent you pay and the variable income you collect.
- Section 8
The federal Housing Choice Voucher program that subsidizes rent for low-income tenants — the government pays a portion directly to the landlord every month.
- Solar Loan & PACE
Financing used to install solar panels — as a loan secured by the equipment or, with PACE, as a lien repaid through the property tax bill — and a due-diligence trap when buying a home with solar.
- Tenant Turnover
The cycle of a tenant moving out and a new one moving in — each turnover triggers leasing fees, vacancy, and make-ready costs, making long tenancies highly valuable.
- Vacancy Rate
The percentage of time a rental sits empty — lost income that underwriting must budget for even though nobody sends you a bill for it.
Financing
- Agency Loans
Multifamily and commercial real estate loans backed by Fannie Mae, Freddie Mac, or HUD/FHA — offering long terms, low fixed rates, and non-recourse options for qualifying properties.
- All-In-One Loan
A first-lien mortgage that merges a checking/sweep account with a HELOC, so every dollar you deposit automatically offsets the loan balance each day — the US version of an offset mortgage.
- Average Daily Balance
The interest-calculation method behind a HELOC: interest is charged on the average of each day's balance across the billing cycle, not on a fixed amortization schedule — which is why parking cash against the line saves interest.
- Blanket & Portfolio Loan
Two ways investors finance past conventional limits — a portfolio loan the lender keeps on its own books and underwrites by its own rules, and a blanket loan that covers multiple properties under one mortgage.
- Co-GP
A co-general-partner who shares the sponsor role on a real estate syndication — splitting the capital raise, loan guarantees, asset management duties, and promote economics.
- DSCR
Debt Service Coverage Ratio — a measure of a property's net operating income relative to its debt payments, used to qualify loans based on the asset's income rather than the borrower's.
- First-Lien HELOC
A home equity line of credit that sits in first position — it replaces your primary mortgage instead of sitting behind it, charging variable interest on the daily balance rather than a fixed amortization schedule.
- HELOC Draw Period
The opening phase of a HELOC — commonly about 10 years — when you can borrow, repay, and re-borrow, often interest-only. When it ends, the line converts to an amortizing repayment period and the payment jumps.
- Interest Arbitrage
Borrowing money at a lower rate and deploying it at a higher return to pocket the spread — for example, drawing from a ~7% HELOC to fund a private loan or deal yielding 10–14%.
- Joint Venture (JV)
A partnership where two or more parties combine money, skills, or deal flow on a single project, sharing profits according to a negotiated agreement rather than a fixed security.
- Mezzanine Financing
A layer of debt that sits between the senior loan and equity in the capital stack — higher interest, often convertible, and used to fill the gap when senior debt alone is not enough.
- Mortgage Recast
Re-amortizing a mortgage after a lump-sum principal payment: the lender recalculates a lower monthly payment over the same remaining term at the same interest rate — for a small fee, with no new loan, appraisal, or credit check.
- PITI
Principal, Interest, Taxes, and Insurance — the four components of a typical monthly mortgage payment, and the real cost an investor must budget when analyzing a deal.
- Preferred Equity
An equity position that receives its return before common equity holders — filling the gap in the capital stack with seniority over the sponsor and LPs but below all debt.
- Private Money Lender (PML)
An individual who lends their own capital against a real estate deal — faster, more flexible, and relationship-based compared to institutional banks.
- Self-Directed IRA
A retirement account that can invest in real estate, private debt, and business equity — not just stocks, bonds, or mutual funds.
- Syndication
Pooling capital from multiple passive investors (limited partners) under a sponsor (general partner) to acquire a larger real estate asset than any single investor could buy alone.
- TIP (Total Interest Percentage)
A required mortgage disclosure showing the total interest you'd pay over the full life of the loan as a percentage of the amount borrowed — often cited to make a mortgage sound like a scam, though it ignores inflation and prepayment.
- Velocity Banking
A debt-paydown method that routes all your income through a line of credit — usually a HELOC — to shrink the average daily balance and pay off a mortgage faster, floating expenses on a credit card in between.
Wholesaling & Deal Sourcing
- ARV
After-Repair Value — the estimated market value of a property once all renovations and repairs are complete, used to size offers and refinancing.
- Assignment Fee
The wholesaler's profit for assigning a purchase contract to an end buyer — the difference between the contracted price with the seller and the price paid by the end buyer.
- MAO
Maximum Allowable Offer — the highest price a wholesaler or investor should pay for a property given its after-repair value, repair costs, and required profit margin.
- Transactional Funding
Very short-term financing — often same-day to a few days — that funds the buy side of a back-to-back double close, most common in wholesaling and flipping, repaid within days when the property resells.
