BuyBox vs DealCheck: which one screens your next rental?
DealCheck is the tool BuyBox gets compared to most, so it's worth being precise about the differences. DealCheck is web-and-mobile and spans more strategies. BuyBox is deeper on BRRRR and buy-and-hold underwriting, shows the formula behind every number, and is the only one you can buy once and own.
DealCheck prices checked July 2026 against dealcheck.io/pricing. If they’ve changed since, tell us at [email protected].
Which is cheaper?
DealCheck's paid plans are $10 to $20/mo billed annually (checked July 2026). BuyBox pricing is on our pricing page, and BuyBox is the only one with a one-time lifetime purchase ($349), so past roughly 18 months of a subscription it's the cheaper serious tool.
Why does 'shows the math' matter?
Any calculator gives you a cash-on-cash number. When a lender or partner asks how you got it, BuyBox answers instantly: hover any metric and see the formula and inputs behind it, from a calc engine audited against industry-standard real-estate math.
