Investment mortgages allow investors to leverage property investments by using debt financing. However, there are limits and restrictions on how many investment mortgages an individual can obtain at once. This depends on factors like income, existing debt obligations, credit score, property type and lender policies. Generally, most lenders allow owning 1-4 investment properties before additional scrutiny and down payment requirements kick in.

Investment Mortgage Limits Vary By Lender But Typically Range From 1-4 Properties
Most lenders allow individuals to hold mortgages on 1-4 investment properties before imposing further restrictions or requirements. For example, big banks like RBC, TD and Scotiabank often cap investment loans at 4 properties. Monoline lenders may be more restrictive, capping investment loans at 1-2 properties for new real estate investors. The exact number depends on the lender’s policies as well as the investor’s financial profile and creditworthiness.
Down Payment Requirements Increase After 3-4 Investment Properties
While first-time homebuyers can qualify for 5% down payment mortgages, investment property down payments are typically at least 20%. Once an investor holds 3-4 mortgaged rental properties, down payment requirements often rise to 30% or more of the purchase price.
Debt Service Ratios And Income Levels Limit Maximum Investment Mortgages
Lenders calculate debt service ratios (DSRs) to ensure borrowers aren’t overextended. As an investor adds more leveraged rental properties, their monthly debt obligations increase. Most lenders cap Gross DSRs around 40% and Total DSRs near 45%. This mathematically limits the number of investment mortgages an investor can qualify for at once.
Investment Property Mortgages Often Require Minimum Credit Scores
While homeowners can qualify for low down payment mortgages with a 580 credit score, minimum scores for investment loans are around 650. As an investor takes on more leveraged properties, lenders may require higher scores to offset the increased risk. Stellar credit in the 800+ range gives the highest chance of approval.
Commercial Properties And Non-Conforming Loans Have Lower Limits
Investment mortgages for commercial real estate are restricted faster than residential limits of 1-4 units. Due to increased risk and complex financing, commercial rules limit individuals to around 1-3 mortgaged properties depending on experience. Non-conforming loan programs also tend to have lower caps than standard mortgages backed by government insurance.
In summary, individual real estate investors can generally hold 1-4 residential investment property mortgages before facing tighter rules. Exact limits depend on the lender as well as borrower qualifications like income, credit rating and existing debts. Requirements for commercial and specialty loans are more conservative, usually capping investors to 1-3 mortgaged investment properties.
