Who we are

About GemHaus

GemHaus turns any US address into an investment analysis.

Back

Enter the property, and in about a minute you get a report with an estimated value range, long-term and short-term rent projections, operating expenses, cash flow, cap rate, cash-on-cash return, DSCR, and the comparable sales behind the numbers.

Every report shows its work. The comps it picked, the expense assumptions it used, and which inputs came from you versus public record sit next to the numbers they produced. A figure you read is a figure you can check.

GemHaus also publishes market intelligence reports for US zip codes and cities, covering median rents, days on market, and price trends, plus a daily-screened feed of cash-flowing deals.

Who it's for

  • Investors — the full numbers on a property before you make an offer.
  • Agents — a professional, shareable analysis for investor clients instead of a spreadsheet.
  • Lenders — branded portals that let borrowers and agent partners analyze deals faster.
  • STR property managers — owner-ready analysis for the next acquisition conversation.

Why it exists

GemHaus was founded by Leah Walczak. After ten years selling residential real estate in Los Angeles, she built and exited a short-term rental management company and brokerage in Scottsdale. She kept hitting the same wall: the data to underwrite a deal was scattered everywhere, and only institutional players had it in one place. She built GemHaus to level the playing field.
