# PorchFacts

> PorchFacts compares living in, renting, Section 8, and flipping one U.S. property, with the public source behind every number. PorchFacts was formerly called Section 8 Yield.

PorchFacts answers, for one U.S. home: what it really costs to live in, what it earns as a traditional rental and as a Section 8 (Housing Choice Voucher) rental, and what a fix and flip could net, with the maximum offer and a confidence grade. Every number carries Verified or Estimated, an evidence tier (your number, area statistic, modeled, published record), a public source link and an effective date.
