Are you planning to deal with all the complexities that each market brings? For example, compare with one of the standard German property search websites: https://www.immobilienscout24.de/ and here are some things that I, personally, would or have used when searching for property that I don't immediately see on your site:

For apartments:

* Searching by floor (or below or above floor)

* Searching by presence/absence of elevator

For all property types:

* Searching by rented / unrented status (evicting tenants for your own use is hard)

* Searching by build phase, if you're interested in new-build properties

* Searching by build year (some people prefer Altbaus, some consider them the work of the devil)

* Searching by heating type (underfloor vs radiator)

* Searching by rooms, not bedrooms. In Germany, a 1-room flat is a Studio Apartment and doesn't have a bedroom.

* Display of and searching by fees when buying (typically this is searching for "no estate agent fee")

* Display of and searching by Warm & Cold rent when renting

* Ability to search by state & city (at a bare minimum, and note that state affects how much property tax has to be paid when purchasing)

I think most countries are going to have a lot of little quirks like this, and it's going to be a hard sell to get people to switch over until you've got a lot of these in place for each country. I know that I've used international sites like this in the past and ultimately abandoned them because they either made it too difficult to find what I wanted, or there just weren't enough properties on there.
