Key ideas in Investing in Real Estate
- Real estate builds wealth through multiple channels beyond simple price appreciation
- Tenants pay down the mortgage balance directly through monthly rent, increasing equity without extra cash from the landlord
- Depreciation is an accounting deduction that lowers taxable income without spending cash that month
- Paper appreciation is locked in the asset and cannot pay immediate, ongoing operating expenses
- Positive cash flow provides the liquidity needed to withstand vacancies and economic slowdowns
- Speculating purely on future property price growth puts an owner at risk of running out of money before gains are realized
- Infrequent but expensive repairs, like replacing a roof or HVAC system, occur every few years
- Failing to set aside monthly reserves for major future repairs creates 'phantom cash flow' that disappears as soon as big systems fail
- True cash flow only counts what remains after budgeting for vacancies, maintenance, and capital expenditures
- A fixed-rate mortgage payment stays identical for the life of the loan regardless of inflation
- Market rents tend to rise over time alongside local cost-of-living increases and inflation
- The gap between increasing rental revenue and static monthly debt payments widens an investor's cash flow over time
- Gross rental income counts only the total rent coming in before any bills are paid
- Net Operating Income subtracts day-to-day operating expenses from gross rent
- Mortgage payments are debt costs, not operating expenses, so they are excluded from NOI
- Capitalization rate is calculated by dividing annual Net Operating Income by the purchase price
