PropertyInvestmentCalc is small on purpose: one person owns and maintains the site, one person writes and edits the guide articles. Both are named below, with a link to how the calculators and content actually get produced.
Jessica Martinez
Real Estate Finance Editor
Jessica writes and maintains the guide articles on this site, the DSCR loan explainer, the cap rate and cash-on-cash breakdowns, the 1% rule and gross rent multiplier pieces, and the step-by-step rental analysis framework. Her focus is showing the arithmetic behind each concept rather than stopping at a definition: a worked example with real dollar figures runs through most of what she publishes here. She updates a guide when a rate range, a lender requirement, or a worked example needs refreshing, rather than on a fixed schedule.
Chris Terry
Owner
Chris owns PropertyInvestmentCalc and a handful of other independent calculator sites. He builds and maintains the five calculators on this domain, checks that the underlying formulas still match current lending and tax rules, and reads every message that comes in through the contact page personally. Chris is not a content byline on this site; his role here is upkeep and accountability, not writing the guides.
