The rental yield calculator is built for investors who want a fast read on property income quality before a full underwriting pass. It helps you move from headline rent to gross yield, net yield, cap rate, and the 1 percent rule using expense assumptions that reflect ownership reality.
The calculator estimates gross yield, net yield, cap rate, annual NOI, GRM, and whether the deal clears a simple 1 percent rule screen. It is useful early in the process when you need a fast but grounded read on a rental.
Rent quality, vacancy, taxes, insurance, management, and maintenance assumptions drive the result. Yield gets distorted quickly when expenses are left out or normalized too aggressively.
Yield and cap rate are starting points, not final answers. A property can post an attractive cap rate and still be weak once financing, location risk, or rehab needs are layered back in.
Rental yield is a broader term that often refers to gross or net yield, while cap rate usually refers to NOI divided by property value or purchase price.
The 1 percent rule is a fast screening rule of thumb that compares monthly rent to purchase price. It is useful for quick filtering, but it should not replace full underwriting.
Yes. Weak financing terms, unstable rent assumptions, heavy deferred maintenance, or poor execution conditions can still make the deal unattractive.
