After owning your own home for some time, you might be able to use the equity within your home loan to buy a second property.
For example, if your own home’s property value has appreciated significantly, the bank/lender might consider using some of that appreciation to lend money to help you buy another property.
That second property can be an investment or rental property. Depending on your circumstance, you could be a landlord yourself.
Being a landlord can potentially be a good way to build wealth and also at the same time support another family into their own home.
