There are two variables to consider - mortgage type, and interest rates. These are the most important considerations when deciding on real estate, so it is essential that you have a basic understanding of what they are. Your two main options are repayment and interest-only types, and under those are more specific kinds.

Repayment Mortgages

This type of financing operates like a simple loan. Every month, you make a payment and the money goes to both the capital (the actual home itself) and the interest. The loan lasts a certain period of time, and if you make all of your payments according to schedule, you will have both the interest and capital paid off at the end of that term.

Interest-Only Mortgages

With this type of payment option, you are making your payments to the lender for the interest only. These loans have other options for paying off the capital in a lump sum. These have their benefits, but they are only good for those who can definitely make those payments according to schedule. If you do not keep up your payments, you risk losing the loan.

You will be saving the money for the capital in a savings plan of some sort, like a pension plan, ISA or endowment. At a certain time, that saved money will be used to pay for the mortgage, and the interest will already have been paid off.

- Endowment Mortgages.

With this type of financing, you are paying money into a life insurance plan. Those funds will eventually be used for the house. At the end of the term, this money will go to the house. The advantage is that you are not only saving for your mortgage, but also getting life insurance. If you die during the payment period, the loan will still be paid off so your family doesn't have to worry. You also might end up with extra cash left over after it's paid off.

- ISA Mortgages. With an ISA, your monthly payments are being split two ways. One part is used to pay the interest on the principle (or original amount you borrowed), and the other goes into an ISA plan, which is invested. Part of the ISA plan will be simple savings, and the rest will go into stocks and other investments. This is an excellent way to pay off your loan like a repayment mortgage, but save lots of money on taxes.

- Pension Mortgages. You pay money into a pension that will be used to pay for the house when you retire. This option is usually only available to those who are self-employed. You are basically saving for both your home and retirement, so you have to make sure that there will be enough when you retire for the house and to take care of you throughout the rest of your life. With this type, you pay almost no tax on your house, and end up saving all that extra money.

Once you've decided which payment plan is best for you, you will have to choose an interest rate. Whether you need a fixed interest rate, variable rate or capped rate will depend on your lender and your own personal needs. Having advanced knowledge about your options will let you select the plan best suited to you and your future.
