New to Houston Real Estate. What Are Investors Looking For in Heights & Spring Branch

Hi everyone — I'm new to real estate and teaching myself how to find off-market opportunities in the Houston area, currently focused on the Heights and Spring Branch. I'm curious what investors and builders active in these neighborhoods actually look for in a deal — lot size, property condition, price range, timeline, that kind of thing. Still learning, so any insight from people with more experience would be genuinely helpful. Not selling anything here, just trying to understand the market better as I get started.
