Swap, don't sell
A marketplace for permanently exchanging property instead of buying and selling. Every listing carries both the home an owner has and the one they want, matched on a swap value range - with a legal-advisor marketplace and membership tiers around it.

What is Property Swap?
Buying and selling a home means two transactions, two chains and two sets of fees. Property Swap collapses that into one: two owners who each want what the other has, exchanging permanently.

Every listing states what you have and what you want
A normal listing says 'for sale'. A swap listing says both halves - the full detail of the property on offer, and a desired-property spec describing what its owner is looking for - so the marketplace can match on the overlap rather than on a single asking price.
Why build a swap marketplace at all?
Swapping property is older than the listings portal, but the tools never caught up. Owners who would happily exchange cannot find each other, and when they do, the paperwork has no home. The marketplace fixes both.



| Moving home | Buying and selling | On Property Swap |
|---|---|---|
| The transaction | Two deals, two chains | One permanent exchange |
| What a listing says | 'For sale' at a price | What you own and what you want |
| Matching | By asking price | By overlapping swap value ranges |
| Reach | Local market | Global, in a common currency |
| Legal help | Found separately | Advisors listed on the property |
The surfaces a swap runs on
From the marketplace landing to a full property record carrying both halves of a swap, every screen is built to help two owners judge whether an exchange is worth pursuing.
How do two owners agree a swap?
When one owner's desired spec overlaps another's property, the marketplace connects them - and brings a legal advisor into the same thread. This is how a match becomes an agreed exchange.
The transcript demonstrates the marketplace's owner-to-owner and legal-advisor messaging; it is a walkthrough of the feature, not a record of a real exchange.
What does the marketplace look like, and why?
A trustworthy marketplace navy carries the brand and every primary action, with a single warm accent reserved for the one number that matters - the swap value range. It reads as considered and financial, which is the register a permanent property exchange needs to earn.

Building a two-sided property marketplace
What founders ask us first when they want to build a marketplace like Property Swap.
Ask us yoursHow long does it take to build a property marketplace?
A two-sided marketplace with rich listings, search, a map, messaging and membership typically takes four to six months. The matching model and the two-sided listing - offered plus desired - drive the date more than the catalogue pages do. We usually build listings and search first, then messaging, memberships and the advisor side around them.
How much does a marketplace like this cost?
It depends on scope, and no honest number comes off a feature list alone. The biggest drivers are the matching logic, whether payments and membership billing are in scope, and how much of the listing detail is structured. Shanti Infosoft scopes it on a short call and returns a fixed quote.
How does swap matching actually work?
Every listing carries two halves - the property on offer with its swap value range, and a desired-property spec. The marketplace matches one owner's desired spec against other owners' properties and value ranges, so two people who each want what the other has can find each other.
Where do legal advisors fit in?
A permanent swap is a legal exchange, so advisors are part of the marketplace, not an afterthought. Local legal advisors are listed against regions, brought into owner conversations, and can advertise their own services to swappers.
How does the marketplace make money?
Through tiered membership - private, business and professional plans that set how many properties an owner can publish, photo allowances, chat contact and more - alongside the paid advisor listings. The exact model is a decision we help you make during scoping.
