Net Yields And Mortgages: Understanding The Intricate Relationship

Net yield is the annual net profit an investor earns on an investment. It is calculated by dividing a security's net realised return by the principal amount. In the context of mortgages, net yield is referred to as mortgage yield, which is the amount of return generated from mortgage-backed securities. This is calculated as the monthly compounded discount rate at which the net present value of all future cash flows from the bond is equal to the present price of the bond. Bond prices and mortgage interest rates have an inverse relationship, meaning that when bond prices increase, mortgage rates decrease, and vice versa. This relationship is important for investors to understand when considering the potential returns on their investments.

How are Net Yields Related to Mortgages?

Rental yield

Calculating the net rental yield involves taking your annual rental income, deducting any costs, and then dividing this figure by the property's value. This gives you a net yield percentage. For example, if you are charging £800 per month in rent, or £9,600 per year, this is your annual rental income. You then need to deduct any costs, such as maintenance, letting agent fees, and mortgage borrowing costs, from this figure. This gives you your net rental income. Dividing this by the property's value and multiplying by 100 gives you the net yield percentage.

A gross rental yield of 5% or more is generally considered a good figure, but higher yields can be found in certain areas. For example, Sunderland, Dundee, and Burnley have been identified as having average yields of around 8%. To get the best rental yield, it is important to research local rental markets, as well as factors such as employment and infrastructure.

Additionally, mortgage rates are influenced by the bond market, which has an inverse relationship with mortgage interest rates. When bond prices are high, mortgage rates are lower, and vice versa. This is because mortgage lenders set their rates slightly above bond yields to attract investors.

Bond prices and mortgage interest rates

The inverse relationship between bond prices and mortgage interest rates can be counterintuitive. When interest rates are higher, more people will want to buy bonds, so it might seem illogical that higher interest rates do not push bond prices up. However, this can be explained by the fact that a change in interest rates, up or down, makes previously issued bonds more or less attractive to investors compared to new bonds issued after the change. If interest rates rise, investors will not want existing bonds with a lower fixed interest rate, and their prices will decline until their yield matches that of new bond issues.

The bond market is often a reflection of other key economic factors. For example, if the economy grows rapidly and inflation rises, bond yields tend to follow. Bond yields also tend to rise if the Federal Reserve raises the short-term interest rate it controls, the federal funds target rate.

Bond prices only influence fixed-rate mortgages. This is because mortgage lenders only attach fixed interest rates to bond rates. Adjustable-rate mortgages are influenced by the Federal Reserve's most recent interest rate decision.

Calculating the yield of a bond can be done in several ways, depending on the type of asset and the type of yield. The yield of a bond can be analysed as either cost yield or current yield. Cost yield measures the returns as a percentage of the original price of the bond, while current yield is measured in relation to the current price.

Mortgage-backed securities

Mortgage rates are influenced by several factors, including an individual's down payment, credit score, and loan type. However, bond prices also play a significant role in determining mortgage rates. There is an inverse relationship between bond prices and mortgage interest rates. When bond prices increase, mortgage rates tend to decrease, and vice versa. This relationship is due to mortgage lenders tying their interest rates to Treasury bond rates.

MBS yields tend to be relatively high, making them attractive to investors seeking stable, fixed-income returns. Agency MBS, which are guaranteed by the US government, have seen significant growth in daily trading volume. In contrast, non-agency MBS, which lack explicit government guarantees, typically carry higher credit risk and offer higher yields to compensate for the increased risk.

The MBS market has evolved since the 2007-2008 financial crisis, which was largely attributed to the collapse of the subprime mortgage market and the complex web of MBS and derivatives. Today, the MBS market remains a significant component of the global financial system, with increased scrutiny from investors and policymakers.

When considering MBS as an investment, it is essential to understand the risks involved, such as prepayment and extension risk. Prepayment risk arises when falling interest rates prompt homeowners to refinance their mortgages, leading to early pay-off of MBS. On the other hand, extension risk occurs when rising interest rates make homeowners less likely to prepay their mortgages, potentially delaying the return of principal to MBS investors.

Mortgage lenders and interest rates

Mortgage interest is the cost of borrowing money from a lender, expressed as a percentage of your loan amount. It is the amount you pay a lender to lend you money to buy a home. Your mortgage interest rate depends on prevailing rates, as well as your credit score, down payment size, and other factors.

Your mortgage interest is a percentage of your balance, or the amount of money you still owe your lender. As you repay your mortgage, you’ll make monthly payments based on your loan’s terms. At first, most of your monthly payment will go toward interest. However, as you continue to make payments and reduce your principal, more of your monthly payment will go toward repaying your original balance.

The Federal Reserve manages short-term interest rates to control the money supply. When the economy is struggling, the Fed lowers rates. These aren’t the rates given to consumers, but the rates at which banks can borrow money to lend to consumers. When the economy declines and unemployment rates increase, interest rates fall to make it more affordable for borrowers to take out loans.

Mortgage rates are also affected by the bond market. Bond prices and mortgage interest rates have an inverse relationship. When bond prices go up, mortgage interest rates go down, and vice versa. Mortgage lenders set their rates slightly above bond yields to attract risk-averse real estate investors while offering them a safeguard through property collateral.

The Secured Overnight Financing Rate (SOFR) is an interest rate set based on the cost of overnight borrowing for banks. Lenders often use it to determine a mortgage’s base interest rate, depending on the type of home loan. Constant Maturity Treasury rates, or CMT rates, refer to a yield that’s calculated by taking the average yield of different types of US Treasury securities with varying maturity periods, and using it to adjust for a number of time periods. Some mortgage lenders will use this rate to determine interest for adjustable-rate mortgages (ARMs).

A higher credit score indicates the borrower has a good financial history and is more likely to repay debts. This allows the lender to lower the mortgage rate because the risk of default is deemed to be lower. A larger down payment also lowers your monthly mortgage payment and can help your odds of negotiating a lower interest rate.

Rental yield is how much you could expect to receive in rent each year from your buy-to-let investment. Rental yield is expressed as a percentage – reflecting your rental income against the property’s market value. While calculating rental yield can give you an indication of whether investing in a buy-to-let property is worth it, there are other factors to consider. For example, buy-to-let properties come with a lot of startup costs on top of the purchase price, such as maintenance, letting agent fees, and more.

Buy-to-let investments

When it comes to buy-to-let investments, understanding rental yield is crucial. Rental yield is a way of calculating the profitability of a property relative to its value. It is the annual rental income represented as a percentage of the property's value. The higher the rental yield, the better.

There are two types of rental yields: gross rental yield and net rental yield. Gross rental yield is the potential rental income generated by a property relative to its market value. It does not take into account expenses and outgoings such as mortgage payments, maintenance costs, taxes, insurance, and management fees. Net rental yield, on the other hand, provides a more accurate picture of profitability by including these operating expenses in the calculation. It gives investors a more realistic picture of their actual returns and demonstrates true cash-on-cash returns. Net yield is calculated as:

> Net Rental Yield = (Annual Rental Income – Expenses) / Property Value) x 100

For example, if a rental property costs $500,000 and generates $30,000 in net operating income per year after expenses, its net yield would be 6%.

When investing in a buy-to-let property, it is important to consider both types of yields to make informed decisions. Net yield is particularly useful for buy-to-let investors as it helps determine if the investment will cover ongoing costs and provide a healthy return. While a straightforward yield figure may not be as useful when comparing buy-to-let investments to other types of investments, such as stocks and shares, it is still an essential aspect to understand.

Additionally, there are other factors to consider when investing in a buy-to-let property beyond just rental yield. These include location, local rental markets, employment rates, and infrastructure, property type, purchase price, financing costs, and more. It is also important to be aware of the various costs associated with buy-to-let properties, such as start-up costs, maintenance, and letting agent fees.
