Real Estate Finance
This chapter covers how buyers pay for real estate, focusing on mortgages and the note, common loan types and clauses, New York's judicial foreclosure process, the math of interest, points, and ratios, how the primary and secondary mortgage markets keep credit flowing, and the federal disclosure laws (TILA, RESPA, and TRID) that protect borrowers. Practice the calculations shown here in plain arithmetic, because finance questions on the exam frequently involve numbers. Interest rates, loan limits, and disclosure timing rules change over time, so treat specific figures as concepts and verify current requirements with NY DOS and the relevant federal agencies.
Mortgage Basics and Parties
Financing real estate involves two separate but linked documents. The promissory note is the borrower's personal promise to repay the debt; it states the loan amount, interest rate, term, payment schedule, and the consequences of default, and it is the evidence of the debt itself. The mortgage (or in some states a deed of trust, though New York uses a mortgage) is the security instrument that pledges the real property as collateral for the note. If the borrower defaults, the mortgage gives the lender the right to force a sale of the property to satisfy the debt. Understanding that the note is the debt and the mortgage is the security is a frequent exam point. The parties carry specific names. The mortgagor is the borrower, the party who owns the property and pledges it as security. A memory aid is that the mortgagor is the one who gives the mortgage. The mortgagee is the lender, the party who receives the mortgage and holds the security interest until the debt is repaid. New York is a lien-theory state, meaning the mortgagor keeps legal title and possession while the mortgagee holds only a lien against the property; this contrasts with title-theory states where the lender holds title until payoff. The practical effect is that a New York borrower remains the owner and can only be dispossessed through the foreclosure process. Several other concepts round out the basics. Hypothecation is pledging property as security for a debt without giving up possession, which is exactly what a mortgage does: the borrower keeps living in the home while it secures the loan. When the debt is fully paid, a satisfaction of mortgage (or discharge) is recorded to clear the lien from the title. A borrower who wants to sell before payoff must satisfy the mortgage from the proceeds unless the loan is assumable. Priority among liens is generally determined by the order of recording, except that real property tax liens take priority over mortgages, and a purchase-money mortgage may have special priority. Because statutory details and lender practices evolve, verify current with NY DOS.
Loan Types, Clauses, and Judicial Foreclosure
Loans come in several structures, and mortgage documents contain clauses that allocate the parties' rights. A fixed-rate, fully amortized loan keeps a constant interest rate, and each level monthly payment covers the interest due plus enough principal to pay the loan off exactly by the end of the term. An adjustable-rate mortgage (ARM) has a rate tied to an index plus a margin, so the rate and payment can rise or fall over time within caps. A term (interest-only or straight) loan pays interest during the term and the entire principal in a balloon payment at the end. Conventional loans are not insured or guaranteed by the government and rely on the borrower's credit and the loan-to-value ratio; lenders usually require private mortgage insurance (PMI) when the down payment is below a set threshold. Government-backed loans include FHA-insured and VA-guaranteed loans, which have their own qualification rules. Key clauses recur on the exam. An acceleration clause lets the lender declare the entire unpaid balance immediately due upon default, which is a necessary step before foreclosure. An alienation (due-on-sale) clause lets the lender call the loan due if the borrower sells or transfers the property, which prevents free assumption. A prepayment clause addresses paying the loan off early; some loans impose a prepayment penalty, though many residential loans do not, and certain penalties are restricted. A defeasance clause requires the lender to release the lien when the debt is paid. A subordination clause allows a lien to move to a lower priority. An escalation clause allows an interest-rate increase under stated conditions. New York is a judicial foreclosure state, which is a distinctive and testable fact. When a borrower defaults, the lender must file a lawsuit in court, and after the borrower is served and given the chance to respond, the court oversees the process and ultimately orders a public sale conducted by a referee, who delivers a referee's deed to the purchaser. Because it runs through the courts, New York foreclosure is slower and more protective of the borrower than the non-judicial power-of-sale process used in some states. New York borrowers also have an equitable right of redemption to reinstate by paying the debt before the sale, and additional consumer protections such as mandatory settlement conferences may apply. These procedures and timelines change, so verify current with NY DOS and current New York law.
Loan Math and Ratios
Finance questions frequently require simple, plain-arithmetic calculations, and the exam rewards students who can set them up quickly. Start with simple interest, which equals principal times rate times time (I = P × R × T). For a loan of $300,000 at an annual rate of 6% held for one year, the interest is 300,000 × 0.06 × 1 = $18,000 per year, which is 18,000 ÷ 12 = $1,500 per month. On an amortized loan, interest each period is charged on the remaining outstanding balance, so the interest portion of the payment shrinks and the principal portion grows over time, but a single-period interest question still uses the current balance. To find a monthly interest portion: monthly interest = (balance × annual rate) ÷ 12. For a $250,000 balance at 5%, that is (250,000 × 0.05) ÷ 12 = 12,500 ÷ 12 ≈ $1,041.67. The loan-to-value ratio (LTV) equals the loan amount divided by the lesser of the sale price or appraised value, expressed as a percent. A $200,000 loan on a $250,000 property is 200,000 ÷ 250,000 = 0.80, or 80% LTV, which typically avoids PMI; a 90% LTV on the same property would be a $225,000 loan. To find a loan amount from LTV, multiply: 80% of $250,000 = 0.80 × 250,000 = $200,000, so the down payment is $50,000. Discount points are a lender charge to increase yield or buy down the rate, and one point equals 1% of the loan amount. Two points on a $200,000 loan cost 2 × 0.01 × 200,000 = $4,000, paid at closing. Do not confuse loan points (percent of the loan) with commission (percent of the sale price). Finally, the capitalization rate connects income and value: cap rate = net operating income (NOI) divided by value, so value = NOI ÷ cap rate. If a property produces $24,000 of NOI and sells at a $300,000 value, the cap rate is 24,000 ÷ 300,000 = 0.08, or 8%; conversely, $24,000 of NOI at a required 8% cap rate implies a value of 24,000 ÷ 0.08 = $300,000. Practice these until the setup is automatic. Program limits and rate rules change, so verify current with NY DOS and lenders.
Mortgage Markets
The lending system operates through two connected markets, and the exam expects you to keep them straight. The primary mortgage market is where loans are originated, meaning where lenders deal directly with borrowers. Commercial banks, savings institutions, credit unions, and mortgage bankers and brokers make loans to homebuyers, set qualification standards, and fund the closing. Once a lender makes a loan, its money is tied up in that mortgage and cannot be lent again until it is repaid, which by itself would slowly starve the market of new funds. The secondary mortgage market solves that problem by buying existing loans from primary lenders. When a lender sells a loan into the secondary market, it receives fresh cash it can use to originate new loans, so the same pool of capital can serve many more borrowers over time. This process provides liquidity, keeps interest rates competitive, and standardizes underwriting, because loans must meet the buyers' guidelines to be salable. Loans that meet the size and quality standards of the major secondary-market entities are called conforming loans; those that exceed the size limit are jumbo loans, and those that fail quality standards are non-conforming. The principal players are the government-sponsored enterprises Fannie Mae (the Federal National Mortgage Association) and Freddie Mac (the Federal Home Loan Mortgage Corporation), which buy large volumes of conventional conforming loans and package many of them into mortgage-backed securities sold to investors. Ginnie Mae (the Government National Mortgage Association) is a government agency that guarantees securities backed by federally insured or guaranteed loans such as FHA and VA loans. The exam tests the roles: primary lenders originate, and the secondary market buys to replenish. When money flows freely into the secondary market, credit is more available and rates tend to ease; when it tightens, lending contracts. Because agency guidelines and conforming loan limits are updated regularly, treat any specific limit as a moving figure and verify current with NY DOS and the agencies.
Borrower Protections: TILA, RESPA, and TRID
Several federal laws require lenders to disclose loan costs and terms so borrowers can shop and compare, and they are frequently tested. The Truth in Lending Act (TILA), implemented by Regulation Z, requires disclosure of the annual percentage rate (APR) and the finance charge. The APR reflects the true, effective cost of credit because it folds certain fees and points into the rate, making offers comparable in a way the note rate alone cannot. Regulation Z also governs advertising: if an ad states one specific credit term that is a 'trigger term' (such as the down payment amount, monthly payment, or number of payments), it must also disclose the other key terms so consumers are not misled. TILA gives a borrower a limited right of rescission on certain refinances of a principal residence, though not on a purchase-money loan. The Real Estate Settlement Procedures Act (RESPA) is a consumer-protection law that applies to most federally related residential mortgage loans on one-to-four-family properties. RESPA prohibits kickbacks, referral fees, and unearned fees among settlement-service providers, requires disclosure of affiliated-business arrangements without requiring the consumer to use the affiliate, and limits the amount a lender may require in an escrow (impound) account. This is why paying a broker or agent for steering a client to a particular title company or lender is illegal. Since 2015, the two older disclosure regimes were combined into the TILA-RESPA Integrated Disclosure rule, known as TRID, enforced by the Consumer Financial Protection Bureau. Under TRID, the borrower receives a Loan Estimate shortly after applying, which states the estimated interest rate, payments, and closing costs, and a Closing Disclosure that the borrower must receive at least three business days before consummation of the loan so they can compare final terms to the estimate. This waiting period gives the borrower time to review costs before signing. Lenders also often maintain an escrow account, collecting a portion of annual property taxes and hazard insurance with each monthly payment and paying those bills when due, with a periodic escrow analysis adjusting the payment. Timing rules, thresholds, and forms are periodically updated by federal regulators, so treat the three-day rule and other specifics as current concepts and verify current with NY DOS and the CFPB.
