When player enters the house you need to chech what is house ID ( I'm gonna pretend it's 1)

So, when player enters house

pawn Код:

SetPVarInt(playerid, "InHouseID", /*Here you put your code to set house ID to player, mine is ->*/1);

And when he exits the house

pawn Код:

new hID = GetPVarInt(playerid, "InHouseID"));
//Open the file where you have your houses saved and just...
SetPlayerPos(playerid, House[hID][exitX], House[hID][exitY], House[hID][exitZ]);

Something like this...
