Buy-and-hold aka rentals are a fantastic way to build wealth for you, family, and future generations. In a nutshell, the basic principle behind rentals is that the total rents (income) received from a property exceeds total costs (expenses). Income from an income-producing property could be rents, laundry and storage fees, space rent and more. Expenses include things like utilities, insurance, taxes, mortgage and vacancy, maintenance and capital expenditure rates.

The benefit of buy-and-hold strategies is trifold:

1) Cashflow
2) Debt paydown (your mortgage getting paid off)
3) Appreciation (overall rise in property values that meets or exceeds inflation)
