The investor advantage
Appreciation Is Not Cash Flow
That appreciation box on the homepage is a price index for the Houston metro. It tells you how sale prices have moved. It is not the rental income, and it does not replace the cash needed before the first rent check. People add it to the rent sheet because it feels like money. It is not in the account.
Keep the chart out of the checking account
A rising metro average is easy to scribble onto a rent projection. I leave it off. The rent is what pays an empty month, a tax bill, and a repair while you own the house. The index might become money on a sale, after selling costs and the loan payoff, and that sale is its own plan. You get a clean read. What the house earns is one column. What a later price might do is another.
What those three figures are
The homepage shows 3.4% for the past year, 5.8% a year over five years, and 5.4% a year over ten years. Those are compound annual averages from the FHFA all-transactions House Price Index for the Houston-The Woodlands-Sugar Land metro, through the second quarter of 2026. A compound annual average is the steady yearly pace that connects the start of the period to the end. It describes the path the index took. Next year is still its own year.
A yearly average is a yearly average
Five times 5.8 is 29. That reading misses what the figure is. The 5.8% figure is an average per year. Compounded, 5.8% a year for five years is about a 33% change in the metro index. Ten times 5.4 is 54. Compounded, 5.4% a year for ten years is about a 69% change in the index. Those totals are the math on the rounded yearly figures. They describe the index. Cash is a different column.
A sale is the moment that index might become money, and only after selling costs and the loan payoff. Until then, the bills come off the rent, which is the expense and fee breakdown. The sale itself is one of the exits in the resale plan, and it works when the price you pay still leaves a buyer behind you.
One house is its own number
The index covers the Houston-The Woodlands-Sugar Land metro. A single house can lag it or run ahead of it. A new section full of identical listings, a street that is hard to rent, or a price that was set by a peak nightly rate can miss the metro average in either direction. The first year of a new house is the stretch where that shows up. The homepage line says these are area examples. An area average is not your house is the longer version of that sentence.
What ROI means here keeps rent, cash, and a later sale in separate columns. A builder incentive does not turn the index into cash either. Rent is what a guest or a tenant pays. Appreciation is what a later price might do.
Let's talk while this is still an idea. I will walk you through why a rising price chart does not pay the house.
