Market readWait
Prices are down 3.6% on the year and more than a third of sellers are cutting. Buyers have room to push. The rent covers the mortgage on paper, but not at today’s asking price. Offer under ask, or wait for a better one.

At $95k with $1,646 rent, this clears the 1% rule with room to spare, so the cashflow is real from day one. The watch-item is the county’s slow population decline. Treat appreciation as a bonus, not the plan.

Questions
Straight answers.
Do I start with a market or a property?
Either. Start with a ZIP to find the right market, or drop in an address to underwrite a specific deal.
How does this fit with my own spreadsheet?
Your spreadsheet might be excellent. Dynamic.re handles the repetitive first pass — pulling the property, rent, and market into one standardized underwrite — so a deal reaches your model already screened, with every assumption laid out to change.
How do you estimate rent?
Estimated market rent comes from nearby rental data. HUD Fair Market Rent is shown separately as an external benchmark, not a property-specific figure — and you can override the rent assumption anytime.
How is it different from Mashvisor or DealCheck?
Those hand you inputs to plug in yourself. Dynamic.re standardizes the first-pass underwrite and scores the property against its market, so you get a defensible read, not just raw numbers.
What do I get after an analysis?
Cash-on-cash, DSCR, monthly cashflow, and cap rate, plus the market context, the risks that could sink the deal, and the price the numbers need.
Is it really free?
Market data on any ZIP is free to look at, and you get five full property analyses a month at no cost, no card required.
