Frequently Asked Questions
Q:What is the 1% rule in rental property investing?
The 1% rule is a quick screening guideline stating that a property's gross monthly rent should be at least 1% of the total purchase price to generate positive net cash flow.
Q:How should I budget for long-term capital expenditures (CapEx)?
Experienced landlords typically allocate 5% to 10% of monthly gross rent toward CapEx reserves to fund major replacements like roofs, HVAC systems, and water heaters.
Q:What is the 50% rule for rental operating expenses?
The 50% rule assumes that approximately 50% of gross rental income will be consumed by operating expenses (excluding mortgage principal and interest payments).
Q:How does depreciation shelter rental income from income taxes?
The IRS allows residential real estate investors to depreciate the building value over 27.5 years, creating non-cash paper losses that offset taxable rental cash flow.
