DealCheck is the better and far cheaper deal calculator for flips, rentals, BRRRR and wholesale numbers (free to start, Pro $20/month). Mashvisor is a market research tool for finding rental and Airbnb markets and properties, and it costs more ($49.99 to $99.99/month billed annually).
Both DealCheck and Mashvisor help you decide whether a property is worth buying, so they get compared a lot. But they answer different questions.
DealCheck asks: given this property and my assumptions, what are the numbers? It is a deal analyzer with calculators for rentals, flips, BRRRR, multifamily and wholesaling, plus comps and branded reports. Mashvisor asks: where should I buy, and what will this place rent for, long term or on Airbnb? It is built around rental data, neighborhood analytics and heatmaps.

DealCheck is hard to beat for running numbers. You can model creative financing, rehab budgets and long-term projections, then share a clean branded report with a lender or partner. The Purchase Offer Calculator helps you back into a max offer, which wholesalers and flippers use daily.
Mashvisor can estimate a property's rental income and returns, and it lets you customize expenses, but its strength is the data behind those estimates rather than flexible modeling.
This is where Mashvisor earns its price. Heatmaps show which neighborhoods have the best rental income, cash on cash return and Airbnb occupancy. The Smart Property Finder compares markets side by side, and the short-term rental rules for 500+ cities can save you from buying an Airbnb where non-hosted rentals are not allowed.
DealCheck does not try to do this. You bring the property, it does the math.
DealCheck's free plan is genuinely useful, and Pro is $20 a month for unlimited saved properties and comps. Mashvisor starts at $49.99 a month on annual billing, and its pricing FAQ says it does not offer refunds, so it is a bigger commitment.
Ask yourself whether you already know where you want to buy. If you do, and you just need confidence in the numbers on a specific house, DealCheck's free plan is enough to start, and its 14-day trial lets you test Pro. If you are still choosing a city or neighborhood, especially for short-term rentals, Mashvisor's market data is what you are paying for. Because Mashvisor bills annually and does not offer refunds, read its plan details carefully before you commit.

DealCheck. It has wholesaling tools, ARV estimates and a purchase offer calculator, while Mashvisor focuses on rental income.
If you need to underwrite deals, start with DealCheck's free plan and upgrade when you hit the limits. If you are hunting for rental or Airbnb markets and want the data to back it up, Mashvisor is the tool, just know it is an annual commitment.
