Comparison
How Prelio compares
Other tools run the numbers on a deal. Prelio runs them and tells you how much room is left in the asking price, and shows the arithmetic. It's free if you're the one buying. The rows we lose are in here too.

What's in this comparison, and what isn't
These six are the tools a buyer would actually pick between. We left out HouseCanary and Roofstock. HouseCanary sells valuation data to big companies. Roofstock is a marketplace for buying and running rentals. Both are good at their job. Neither one scores a deal, so lining them up row by row wouldn't tell you much.

Trade-offs
Where Prelio loses
If one of these is what you need, go buy the other tool. Better you find out here than after you've paid us.
Finding properties - Ziffy, Mashvisor
Both go out and find deals you haven't seen yet. Prelio starts from an address you already have. If you need a list of properties to work through, start with them.
Comps depth - PropLab
PropLab weights each comp by distance and how recently it sold, and shows you the adjustment on every one. You can hand that to a lender. Ours are fine, but they're not why you'd use Prelio.
Rehab, ARV and flips - FlipperForce, PropLab
We don't estimate repair costs, and we don't tell you what a house is worth after the work is done. If you flip houses, that's most of the job, and we don't do it.
Project tracking - FlipperForce
Schedules, budgets and expenses once you own the place. Prelio stops the day you make the offer.
The claim
What sets Prelio apart
One row in the table has a single Yes, and it's ours. The other two are about who pays, and what the AI is actually looking at.
01
Know how much room is actually left
Every other tool works out your offer from the deal math: repair costs, the 70% rule, the return you want. None of them read the seller's position. How long the house has sat sets the range, against sale-to-list bands the National Association of Realtors publishes. What the seller has already given up against the Estimate comes off it. What is left is the room, in percent and in dollars, and we show the subtraction rather than folding it into a score you would have to take on trust. Look at that row in the table. Every other column says No.
02
Never pay to find out a deal is bad
Everyone else puts a meter on the buyer. Three analyses. Five analyses. Or a monthly fee before you've made a single offer. With Prelio the buyer pays nothing and gets the whole thing, including a Deal Brief you can send to anyone. Realtors pay $29 a month for white-labelled reports and weekly foreclosure alerts, and a whole office is $129. Most deals you look at won't work, and you shouldn't be charged to learn that.
03
Get a straight answer on this one house
Three other tools here use AI, and all of it points somewhere else. PropLab at repair costs and resale value. Ziffy at finding listings. Mashvisor at a market score. Prelio writes a few plain sentences about the house you're looking at, using that house's real numbers, and gives you an offer range. No jargon, and you can see every signal behind it.
