Read the guideFive questions. One clearer decision.
You do not need a perfect forecast. You need to know what drives the result—and what still needs checking.
- 01What rent does the evidence support?
- 02What will the property actually cost to own?
- 03What cash is left after financing?
- 04What return does your committed cash produce?
- 05What happens when the assumptions get worse?
Useful research beats confident guesses.
These are original educational guides, not market forecasts or live listings. Every financial example is hypothetical and before tax. We show the assumptions, check the arithmetic and link the primary references so you can inspect the reasoning.
