Which calculator should you use?
Every investment strategy uses a different set of numbers. A cap rate that would kill a fix and flip is fine on a long-term rental. A BRRRR project that recycles 100% of your capital doesn't need to hit the 1% rule. Pick the calculator that matches how you actually plan to make money on the deal.
