The Problem

Most investors only track cash flow — they miss 75% of their return.

Cash flow gets all the attention, but it's only one of four ways real estate builds wealth. If you're making decisions based on cash flow alone, you're missing the appreciation, principal paydown, and tax benefits that often dwarf your rental income.

The Solution

See the complete picture with all four return streams.

Appreciation: $11,550/yr
Cash Flow: -$9,942/yr
Debt Paydown: $2,933/yr
Tax Benefits: $2,688/yr
Total Year 1 Return: $7,229/yr
