Planning a Home, a Car and Other Major Purchases

A home, a car, a wedding, a new baby: the largest purchases most people make are also the ones most often decided by a monthly payment and a feeling. A payment that fits this month's budget can hide a total cost twice the sticker price, and a purchase made in a hurry gives up the bargaining power that comes from being able to walk away. This chapter shows how to price a big purchase in full, how to save for it, and how to time and negotiate it.

Price the whole thing, not the payment

Every large purchase has four layers of cost, and the sticker price is only the first.

• Buying it. The price, sales tax, fees, closing costs, delivery and setup.
• Financing it. Interest over the life of any loan, plus origination fees, points, and mortgage insurance if you put down less than 20% on a home.
• Keeping it. Insurance, maintenance, repairs, property tax, association dues, utilities, fuel.
• What else the money could have done. Cash tied up in a purchase is not growing elsewhere, and a large payment limits every other goal in chapter 1.

The monthly payment hides the second and third layers. A longer loan lowers the payment and raises the total, so a lender or dealer who asks "what payment are you comfortable with?" is steering you toward the number that matters least. Ask for the total instead.

A home: what to have before you buy

A home is usually the largest purchase of a lifetime, and the loan is a large part of its cost. Here is a mortgage of $320,000 at 6.5% over 30 years:

The payment is $2,023 a month for principal and interest, but over the full term the borrower pays $728,142, of which $408,142 is interest. The same amount over 15 years, where rates are usually somewhat lower (here 6.0%), looks very different:

The payment rises to $2,700, and total interest falls to $166,062. The shorter loan is not automatically better: the higher payment leaves less room for retirement saving and the emergency fund, and the longer loan can be paid down faster by choice. But it shows what the term really costs. Neither figure includes property tax, insurance or upkeep, which together often add a large share to the monthly cost.

Before buying, most of these should be in place:

• A down payment. Putting down 20% avoids private mortgage insurance on a conventional loan; less is possible, with insurance added to the payment until you reach enough equity.
• Closing costs, saved separately. These typically run a few percent of the price. Your lender's Loan Estimate lists them.
• An emergency fund that is not the down payment. New homeowners meet repairs quickly. Emptying every account for the purchase leaves nothing for the first broken water heater.
• A debt-to-income ratio a lender will accept, with room in your own budget beyond what the lender allows.
• Stable income and a strong credit score, which bring a lower rate.
• A plan to stay several years. Buying and selling costs mean a home bought and sold quickly usually costs more than renting would have.

Saving the down payment is a classic medium-term goal. Starting with $10,000 and adding $1,200 a month in a savings account paying 4.0%:

After 4 years the fund holds $73,961. Money needed within a few years belongs in insured savings or Treasury bills, not stocks, because a market fall the year you plan to buy would push the purchase back. The down payment savings calculator shows how long your own target takes, and the home affordability calculator shows the price range your income supports.

A car: the purchase that shrinks

Cars lose value from the day they are bought, and new cars lose it fastest in the first few years. That is why a car that is two or three years old often gives the best balance: someone else has absorbed the steepest drop, and much of the reliability remains. An older car costs least to buy but more to repair, and a lease means paying for the steepest years of decline again and again.

A widely quoted rule of thumb for financing is 20/4/10: at least 20% down, a loan of no more than four years, and total car costs (payment, insurance, fuel, upkeep) under 10% of gross income. It is a guideline, not a law, but it guards against the long, low-payment loans that keep people owing more than the car is worth. Compare a four-year loan with a six-year loan, which often carries a higher rate:

The four-year loan costs $718 a month and $4,483 in interest. The six-year loan lowers the payment to $541 but raises interest to $8,935, and the car will be worth much less when the last payment is made. A car fund like the one in chapter 2 shrinks or removes the loan altogether. The true cost of a car calculator adds depreciation, insurance, fuel and repairs to see what a car costs per year of ownership.

Weddings, babies and education

Life events carry emotion, which is exactly why they need a number decided in advance.

A wedding. Set the budget before anything is booked, because every later decision pushes it up. Guest count drives most costs. Paying in cash means starting a marriage without wedding debt.

A new child. The first year brings medical bills up to your plan's out-of-pocket limit, equipment (much of which can be bought used, except safety items such as a car seat), and, for many families, childcare that rivals a rent payment. Check your employer's parental leave and dependent care benefits early, review life insurance, and use a dependent care flexible spending account if one is offered. Chapter 6 explains it.

Education. A 529 plan lets savings for college and some other education grow free of federal tax when used for qualified costs. Chapter 6 covers how much a monthly amount started at birth can grow, and why many parents fund their own retirement first.

Timing and negotiation

Buying at the right moment can matter as much as saving harder.

Season. Cars are often cheapest near the end of a month, quarter or model year, when dealers chase targets. Appliances and electronics follow new-model and holiday sale cycles. Homes often see less competition in winter.

Rates. When mortgage and auto rates are high, prices may soften, and you can refinance later if rates fall; when rates are falling, waiting can help. Nobody predicts rates reliably, so buy when the purchase fits your plan, not when a headline says so.

Your own position. The strongest bargaining position is being able to walk away. That comes from having the money saved, having more than one option, knowing the fair price, and having no deadline forcing you. Negotiate the total price, not the payment, and arrange financing before you shop so the seller cannot hide cost in the loan.

A simple timeline helps. Eighteen to 24 months out, define what you need and research the full cost. Twelve to 18 months out, automate saving and work on your credit. Six to 12 months out, get pre-approved and watch prices. In the final months, buy when the right option appears, not when impatience peaks.
