📚 The Basics
Start here — the fundamental terms every homebuyer needs to know
A loan you take out to buy a home. The home itself is used as collateral — meaning if you stop making payments, the lender can take the home back (foreclosure).
📝 Example
You want to buy a $300,000 home. You put down $60,000 and borrow $240,000 from a bank. That $240,000 loan is your mortgage.
💡 Why It Matters
Understanding that a mortgage is a secured loan helps you appreciate why lenders care about your credit score and income — they want to make sure you'll pay them back.
The amount of money you actually borrow from the lender. It's the home price minus your down payment.
📝 Example
Home costs $350,000, you put down $70,000. Your principal (loan amount) is $280,000.
💡 Why It Matters
Your principal determines how much interest you'll pay over time. A smaller principal means less total interest.
The fee the bank charges you for lending you money. It's calculated as a percentage of what you still owe.
📝 Example
With a 6.5% interest rate on a $280,000 loan, you'd pay about $18,200 in interest in just the first year.
💡 Why It Matters
Over a 30-year mortgage, you might pay more in interest than the actual home price. Even a 0.5% difference in rate can save you tens of thousands.
The yearly cost of borrowing money, shown as a percentage. A lower rate means lower monthly payments.
📝 Example
A 6% rate on $280,000 = about $1,679/month. A 7% rate on the same loan = about $1,863/month. That 1% difference costs you $184/month or $66,240 over 30 years!
💡 Why It Matters
Your interest rate is one of the biggest factors in how much your home really costs. Shopping around for a better rate can save you a car's worth of money.
The money you pay upfront when buying a home. It comes from your own savings and reduces how much you need to borrow.
📝 Example
On a $300,000 home with 20% down, you pay $60,000 upfront and borrow $240,000.
💡 Why It Matters
A larger down payment means: (1) smaller loan, (2) lower monthly payments, (3) less total interest, and (4) you might avoid PMI.
The fixed amount you pay every month toward your mortgage. It includes both principal (paying down the loan) and interest (the bank's fee).
📝 Example
On a $280,000 loan at 6.5% for 30 years, your monthly payment would be about $1,770.
💡 Why It Matters
Your monthly payment should ideally be no more than 28% of your gross monthly income. This is called the 28% rule.
The number of years you have to repay the mortgage. Common terms are 15 and 30 years.
📝 Example
A 30-year term on $280,000 at 6.5% = $1,770/month. A 15-year term = $2,441/month — higher monthly, but you save $176,000 in interest!
💡 Why It Matters
Shorter terms have higher monthly payments but save you a LOT of money in total interest. It's one of the most impactful decisions you'll make.
💰 Costs & Fees
All the costs beyond the home price that you need to budget for
The true yearly cost of your mortgage, including the interest rate PLUS fees and other charges. APR is always equal to or higher than the interest rate.
📝 Example
A loan advertised at 6.5% interest might have a 6.8% APR once fees are included.
💡 Why It Matters
APR lets you compare loans fairly. A loan with a lower interest rate but high fees might actually cost more than one with a slightly higher rate but lower fees.
An extra monthly fee you pay if your down payment is less than 20% of the home price. It protects the LENDER (not you) if you default on the loan.
📝 Example
PMI typically costs 0.5%–1% of your loan amount per year. On a $280,000 loan, that's $1,400–$2,800/year or $117–$233/month extra.
💡 Why It Matters
PMI is money you pay that provides zero benefit to you. Putting 20% down avoids it completely. You can also request PMI removal once you have 20% equity.
Fees you pay when the home purchase is finalized. These include appraisal fees, title insurance, attorney fees, and more.
📝 Example
Closing costs are typically 2%–5% of the home price. On a $300,000 home, expect $6,000–$15,000 in closing costs.
💡 Why It Matters
Many first-time buyers are surprised by closing costs. Budget for them separately from your down payment so you're not caught off guard.
A special account where your lender holds money to pay property taxes and homeowner's insurance on your behalf. A portion of each monthly payment goes into escrow.
📝 Example
If your property tax is $4,000/year and insurance is $1,200/year, your lender adds about $433/month to your payment to cover these.
💡 Why It Matters
Escrow means you don't have to save up for big lump-sum tax and insurance bills. But it does make your monthly payment higher than just principal + interest.
Annual taxes you pay to your local government based on your home's assessed value. These fund schools, roads, and public services.
📝 Example
Property tax rates vary widely. In Texas it might be 1.8% ($5,400/year on a $300,000 home). In Hawaii it might be 0.3% ($900/year).
💡 Why It Matters
Property taxes are an ongoing cost of homeownership that many first-time buyers forget. They can significantly increase your true monthly housing cost.
Insurance that protects your home and belongings against damage, theft, and liability. Lenders require it as long as you have a mortgage.
📝 Example
Average cost is about $1,200–$2,000/year for a typical home, but varies by location and coverage level.
💡 Why It Matters
Without insurance, a fire or natural disaster could leave you still owing money on a home that no longer exists. It's a must-have.
Monthly or annual fees paid to a Homeowner's Association if your property is part of one. HOAs maintain shared spaces like pools, gyms, and landscaping.
📝 Example
HOA fees range from $100/month for basic communities to $500+/month for luxury condos.
💡 Why It Matters
HOA fees are a permanent, ongoing cost that can increase over time. Factor them in when calculating how much home you can afford.
Upfront fees you can pay to lower your interest rate. One point costs 1% of your loan amount and typically reduces your rate by 0.25%.
📝 Example
On a $280,000 loan, 1 point costs $2,800 and might lower your rate from 6.5% to 6.25%, saving you about $50/month.
💡 Why It Matters
Buying points makes sense if you plan to stay in the home long enough to recoup the upfront cost through lower monthly payments. Calculate the break-even point.
📋 The Buying Process
What happens from pre-approval to getting the keys
A letter from a lender saying they've reviewed your finances and are willing to lend you up to a certain amount. It's more thorough than pre-qualification.
📝 Example
You apply for pre-approval, and the bank says: 'Based on your income and credit, we'd lend you up to $320,000.'
💡 Why It Matters
Sellers take pre-approved buyers more seriously. In competitive markets, not having a pre-approval letter can mean losing the home to another buyer.
The process of gradually paying off your loan through scheduled monthly payments. An amortization schedule shows exactly how much of each payment goes to principal vs. interest.
📝 Example
In year 1 of a 30-year mortgage, about 80% of your payment goes to interest. By year 25, about 80% goes to principal.
💡 Why It Matters
Understanding amortization helps you see why making extra payments early in your loan has a HUGE impact — you're fighting against interest that compounds.
The process where the lender thoroughly reviews your application, finances, and the property to decide whether to approve your mortgage.
📝 Example
During underwriting, the lender will verify your income, check your credit history, review your bank statements, and order a home appraisal.
💡 Why It Matters
Underwriting can take 2–6 weeks. Don't make big financial changes (like changing jobs or buying a car) during this time — it could derail your approval.
A professional assessment of a home's market value. The lender orders this to make sure they're not lending more than the home is worth.
📝 Example
You agree to buy a home for $300,000, but the appraisal comes back at $285,000. The lender will only lend based on the appraised value.
💡 Why It Matters
A low appraisal can complicate or kill a deal. You may need to renegotiate the price, make a larger down payment, or walk away.
Insurance that protects you against problems with the property's ownership history — like unknown liens, disputes, or errors in public records.
📝 Example
You buy a home, and later someone claims they have a legal right to it from a past inheritance dispute. Title insurance covers you.
💡 Why It Matters
It's a one-time cost at closing (usually $1,000–$2,000) that protects your biggest investment from past ownership problems.
The final step of buying a home. You sign all the paperwork, pay closing costs, and officially become the homeowner.
📝 Example
Closing day typically takes 1–2 hours. You'll sign dozens of documents, wire your down payment and closing costs, and get the keys.
💡 Why It Matters
Review all documents carefully before closing day. Once you sign, you're committed. Don't be afraid to ask questions about anything you don't understand.
🏦 Types of Loans
Different mortgage products and which one might be right for you
A mortgage where the interest rate stays the same for the entire life of the loan. Your monthly payment never changes.
📝 Example
You lock in a 6.5% rate for 30 years. Whether rates rise to 10% or drop to 4% in the future, your rate stays at 6.5%.
💡 Why It Matters
Fixed-rate mortgages are the most predictable and popular choice. You know exactly what you'll pay every month for the life of the loan.
A mortgage where the interest rate can change after an initial fixed period. Usually starts with a lower rate that adjusts based on market conditions.
📝 Example
A 5/1 ARM has a fixed rate for 5 years, then adjusts every year after that. You might start at 5.5% but it could rise to 8% or drop to 4%.
💡 Why It Matters
ARMs can save money if you plan to sell or refinance within the fixed period. But they're risky if rates rise and you can't refinance.
A government-backed mortgage insured by the Federal Housing Administration. Designed for first-time buyers or those with lower credit scores.
📝 Example
FHA loans allow down payments as low as 3.5% and credit scores as low as 580. But they require mortgage insurance for the life of the loan.
💡 Why It Matters
FHA loans make homeownership accessible to more people, but the lifetime mortgage insurance can make them more expensive than conventional loans long-term.
A mortgage backed by the Department of Veterans Affairs, available to military service members, veterans, and eligible spouses.
📝 Example
VA loans often require $0 down payment and no PMI. They typically offer lower interest rates than conventional loans.
💡 Why It Matters
If you're eligible, a VA loan is often the best deal available. No down payment and no PMI can save you tens of thousands of dollars.
A mortgage that is NOT backed by the government. It follows guidelines set by Fannie Mae and Freddie Mac.
📝 Example
Conventional loans typically require a 620+ credit score and 3%–20% down payment. With 20% down, you avoid PMI.
💡 Why It Matters
Conventional loans offer the most flexibility and are the most common type. If you have good credit and can put 20% down, they're usually the best option.
A mortgage that exceeds the conforming loan limits set by Fannie Mae and Freddie Mac (currently $766,550 in most areas for 2024).
📝 Example
If you're buying a $900,000 home with 20% down, your $720,000 loan exceeds the conforming limit and would be a jumbo loan.
💡 Why It Matters
Jumbo loans often have stricter requirements (higher credit score, larger down payment) and may have slightly higher interest rates.
🎓 Advanced Concepts
Deeper topics for when you're ready to level up your knowledge
Replacing your current mortgage with a new one, usually to get a lower interest rate, change the loan term, or cash out some equity.
📝 Example
You got your mortgage at 7%. Rates drop to 5.5%. You refinance to the lower rate and save $300/month.
💡 Why It Matters
Refinancing has closing costs (usually 2%–5% of the loan), so make sure the savings outweigh the costs. A common rule: refinance if you can lower your rate by at least 0.75%–1%.
The portion of your home that you actually own — the difference between your home's current market value and what you still owe on the mortgage.
📝 Example
Your home is worth $350,000 and you owe $250,000. You have $100,000 in equity (about 29%).
💡 Why It Matters
Equity is wealth. It grows as you pay down your mortgage and as your home value increases. You can borrow against it (HELOC) or cash it out when you sell.
The percentage of the home's value that you're borrowing. Calculated as: loan amount ÷ home value × 100.
📝 Example
You borrow $270,000 on a $300,000 home. Your LTV is 90% (270,000 ÷ 300,000). An LTV above 80% usually triggers PMI.
💡 Why It Matters
Lenders use LTV to assess risk. Lower LTV = less risk = better loan terms for you. Getting below 80% LTV eliminates PMI.
The percentage of your gross monthly income that goes toward paying debts (mortgage, car loans, student loans, credit cards).
📝 Example
You earn $6,000/month and have $2,400 in total monthly debt payments. Your DTI is 40% ($2,400 ÷ $6,000).
💡 Why It Matters
Most lenders want your DTI below 43%. Lower is better. To improve your DTI: pay off debts, increase income, or buy a less expensive home.
A revolving line of credit secured by your home's equity. It works like a credit card — you can borrow up to a limit and pay interest only on what you use.
📝 Example
You have $100,000 in equity. A lender offers a HELOC up to $80,000. You use $30,000 for a kitchen remodel and pay interest only on that $30,000.
💡 Why It Matters
HELOCs can be useful for home improvements or emergencies, but you're putting your home at risk. If you can't repay, you could lose the home.
A deposit you make when your offer on a home is accepted, showing the seller you're serious. It's typically held in escrow until closing.
📝 Example
You offer $300,000 on a home and include a $6,000 earnest money deposit (2%). If the deal goes through, it's applied to your down payment.
💡 Why It Matters
If you back out of the deal without a valid reason (outside of contingencies), you could lose your earnest money. Typically 1%–3% of the purchase price.
A condition in your purchase offer that must be met for the deal to go through. If the condition isn't met, you can walk away without penalty.
📝 Example
Common contingencies: home inspection (finding major problems), financing (getting approved for the loan), and appraisal (home appraising at the offer price).
💡 Why It Matters
Contingencies protect you as a buyer. Never waive the inspection contingency unless you truly understand the risks.
