Calculating Rental Income for Mortgage Financing

Lenders consider rental income when evaluating borrowers’ ability to repay an investment property mortgage. However, they may not recognize the entire rental income for their calculations. Factors affecting rental income calculations include:

1. Gross rental income: Gross rental income refers to the total income generated by your rental properties before deductions for expenses, such as maintenance, property management, and vacancies.

2. Net rental income: Net rental income is the amount remaining after deducting all expenses associated with owning and operating the rental properties.

3. Percentage of rental income: Lenders typically apply a specific percentage, ranging from 50% to 100%, to the gross rental income to account for potential vacancies and property management-related expenses.

It’s essential to accurately assess and document your rental income, as this will significantly impact the mortgage amount you qualify for.

Understanding Rental Offsets for Mortgage Qualification

Rental offset is another approach lenders use to account for rental income when calculating mortgage qualification. Instead of including rental income in your overall income, lenders offset the rental expenses against the rental income.

For example, if your rental property generates $2,000 in monthly rental income, and the monthly expenses (mortgage payments, taxes, etc.) amount to $1,500, a lender with a 75% rental offset would consider only $375 ($1,500 * 0.75 = $1,125, and $2,000 – $1,125 = $875) to cover the rental property expenses, thus improving your debt service ratios.

Determining Debt Service Ratios for Investment Property Financing

Debt service ratios help lenders assess your capacity to repay a mortgage. Two primary ratios are used:

1. Gross Debt Service Ratio (GDS): The GDS ratio calculates the percentage of your gross monthly income used to cover housing costs, such as mortgage payments, property taxes, and heating expenses. Lenders typically look for a GDS ratio below 35%.

2. Total Debt Service Ratio (TDS): The TDS ratio evaluates the percentage of your gross monthly income required to cover housing costs (as calculated in GDS) and other debt obligations, such as loans and credit card payments. Lenders often seek a TDS ratio below 42%.

Including rental income in your debt service ratios may improve these ratios and help you qualify for a larger mortgage.

Financing Options for Investment Properties

Investment property financing differs from traditional residential mortgages. Here are several financing options to consider:

1. Conventional mortgages: With a minimum down payment of 20% for investment properties, conventional mortgages are popular with investors. However, stricter lending criteria and higher interest rates may apply.

2. Home equity lines of credit (HELOC): If you own a primary residence with sufficient equity, you could access a HELOC to finance your investment property’s down payment or purchase.

3. Private mortgages: Private lenders offer more flexible lending criteria and faster approval processes than traditional lenders, making them an attractive option for investors. However, they typically feature higher interest rates and shorter-term loans.

Enhancing Rental Income for Mortgage Success

To maximize rental income potential and improve mortgage eligibility, consider these tips:

1. Optimal Pricing: Conduct market research and set rental rates based on local market conditions to maximize your property’s occupancy and revenue potential.

2. Regular Maintenance: Ensure regular maintenance and timely repairs, which can help avoid vacancies and maintain tenant satisfaction.

3. Tenant Screening: Properly screen potential tenants to ensure they can meet rental payment obligations and maintain a quality living environment for other occupants.


By understanding the intricacies of leveraging rental income for mortgage financing, investors can take full advantage of their investment properties and secure favourable financing options. Working with a trusted mortgage brokerage like The Mills Team provides comprehensive knowledge and guidance throughout the process, ensuring your investment strategy aligns with your financial goals and broadens your real estate portfolio horizons.
