Understanding the building-blocks of a mortgage may help you compare your options. Your monthly payment is based on a complex calculation that changes over time, so "getting the picture" can be tricky! The biggest pieces are: Loan Amount Interest Rate Term (years to pay off) Payment Schedule Down Payment Equity Down payment and equity are of course closely related, but remember that your equity changes as loan payoff proceeds. This short video visualizes the way these factors relate to help you make sense of the math.

Many people buying a home and shopping mortgages will eventually face the decision: "fixed or ARM?" Its a risk-vs-cost decision. Heres some perspective about fixed-rate options. 15-year Terms are the shortest of the commonly-available fixed rate plans. Interest rates are usually lower for 15-year loans. Payments reduce loan principal earlier, so you build equity (ownership) faster. And, of course, the loan is paid off earlier. 30-year Terms are the longest terms allowed, and probably the most common. For perspective, though, keep in mind that for most 30-year loans, the first 23 years of payments pay off more interest than principal. This may mean larger tax deductions, but it also means more interest paid. Keep your plans for living in mind; how long will you be in this home? What payments make financial sense? Look at the short-term and long-term math for eligible loan amounts, interest rates and payments to make the best decision for your situation.

Many people have been through this decision in the past few years. Its pretty simple; if interest rates drop significantly below the rate of an existing mortgage, refinancing may make sense. Advice from HUD (US Dept of Housing & Urban Development) experts is "2% and 18 months." If you plan to remain in the home for at least a year and a half, and if you can qualify for a rate thats 2% lower than your current rate, refinancing is worth a look. Keep in mind that refinancing is not free. The refi process involves many of the same inquiries, validation and fees as the original financing. "Rolling the costs into the new loan" can mask the long-term financial impact. Compare the math carefully.

Mortgage loans usually take decades to pay off, so the interest rate has a big impact on the actual cost of the loan over that time. A small change in interest rate can make for a huge swing in loan costs or payments. Interest rates fluctuate all the time; see the video on Prime on this website to understand some of the underlying factors. While you are shopping for a mortgage, ask lenders about rate lock-in to give yourself options to handle the immediate market situation. Keep in mind that the full cost of borrowing is higher than the interest rate alone. Lenders will provide an Annual Percentage Rate — APR — in Loan Estimate and Closing Disclosure forms. These include fees, mortgage insurance and the cost of points so you can understand the actual yearly cost. Its easy to get emotional about interest rates in shopping a mortgage; market rates are publicized constantly. Focus on comparing each loan option in its entirety rather than interest rate alone.

Adjustable Rate Mortgages commit buyers to making loan payments that may change over time as market interest rates change. If interest rates go up, payments go up and the borrower has to meet those payment obligations. ARM rates may be lower than fixed rates now. Look at your personal situation to assess if you can handle the risk of future increases. Is your income likely to increase over the years to come? Will you be staying put, or do you anticipate selling the home and moving? While an ARM may put a larger loan amount in reach now, make sure you can keep up with that commitment if rates increase in the future.

This short video summarizes the main kinds of mortgages available for home buyers: Adjustable Rate Mortgage, commonly called “ARM” Fixed-Rate Mortgages Balloon Mortgages 2-Step Mortgages ARMs, as the name suggests, will change over time. As market interest rates vary, the mortgage interest rates and payments will vary with them. Buyers opting for ARM loans take on responsibility for meeting payments even if interest rates go up significantly. Fixed rate mortgages lock in interest rates for the entire loan. If the interest rate on a fixed-rate loan is higher than an ARM today, the rate and payments will not change in the years to come. Balloon mortgages are sort of “shaped like a balloon” — smaller at the bottom, bigger at the top. In financial terms, balloon mortgages provider lower interest rates for the early years of a loan — usually 5 years, 7 years, or 10 years. Then the balance and interest are adjusted and refinanced, which sometimes requires a large ‘balloon’ payment. Two-Step mortgages are like super-simplified ARMs. Interest rates adjust, but only one time. Other options for mortgages are available, and worth investigating for your particular situation. For veterans, VA loans are a frequently a great option; see the VA loan series on this site for additional details. Other government programs for non-veterans may also be available. Real estate professionals and lenders can help you make sense of the current market and the options that might suit you best.

Buying your first home? Many lenders provide affordable mortgage options specifically designed to help first-time buyers. Home purchase is a big and often difficult step; these programs may help. If any of these apply: You have long-term debts You have, or have had, income irregularities Your credit history notes past challenges You have not accumulated enough for closing and down payments First-time buyer programs may be able to help. Talk to lenders early.

Federal regulations for mortgage loans require lenders to assess a home-buyer’s likelihood of paying back the loan over the years ahead. As a result, lenders are required to ask about a borrower’s current financial situation and financial history. Lender questions will cover employment, expenses, assets, income and of course credit history and credit rating. The key thing for the prospective home-buyer to understand is that lenders have to ask these questions and make this assessment. These ability-to-repay rules are built into loans that meet Qualified Mortgage guidelines. If you are shopping and comparing loans, keep track of which options are meet the guidelines to be Qualified.

The down payment on a home affects many things — what home you can afford, loan size, financing terms and more. Getting some sense of the down payment you can afford can be difficult; people are quick to share advice from their experience, but conditions may have changed. In general, the higher the % of the purchase that you can cover in the down payment, the better the loan terms as a whole are likely to be. 5% of the home is currently the minimum down-payment amount. Keep in mind that any amount under 20% will generally require a mortgage insurance policy, which does increase borrowing costs. Keep in mind that the down payment is not the only sizable payment involved in buying a home. You will also need cash for closing expenses, moving, decorating, furnishing and possibly repairs. Check your credit history when youre sizing up down payment and loans; its also a vital part of the equation.

Picture your home loan on one side of a see-saw, and the home itself on the other. Thats a simplified version of LTV — "Loan to Value". Its one of the key ratios involved in setting loan amounts. Lenders frequently set LTV limits. If you know the ratio, you know the upper boundary of loan size, like this: "LTV on this $500K home is 80%." 80% x $500K = $400K max loan. Buyer would need at least $100K down for that loan. LTV also measures equity. If you put $100K down for the example above, you have $100K equity in the home. As a result, higher-LTV loans may require mortgage insurance. With an LTV greater than 80%, the risk of default is high because the homeowner has a lower "stake" in paying off the mortgage.
