I run two side projects atm but they are both becoming more and more the main job. I am building a Zillow for Europe [1]. The real estate market in Europe is a big mess and for the past 10 years not much has happend so far in proptech because it was easy to rent/sell properties.

For apartments:
* Searching by floor (or below or above floor)
* Searching by presence/absence of elevator
For all property types:

* 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.
