You can't use IsPlayerInRangeOfPoint here, though I couldn't. Here's a nice stock which you can use. I don't know who made it originally, but I got it from Jakku.

stock Float:GetDistanceToHouseOutside(playerid,houseid)
{
    new Float:x1,Float:y1,Float:z1,Float:x2,Float:y2,Float:z2;
    GetPlayerPos(playerid,x1,y1,z1);
    x2 =  HouseInfo[houseid][PickupOutsidePosX];
    y2 =  HouseInfo[houseid][PickupOutsidePosY];
    z2 = HouseInfo[houseid][PickupOutsidePosZ];
    return floatsqroot(floatpower(floatabs(floatsub(x2,x1)),2) + floatpower(floatabs(floatsub(y2,y1)),2)+floatpower(floatabs(floatsub(z2,z1)),2));
}

stock IsNearHouseOutside(playerid)
{
    new Float:Distance;
    for(new house; house < MAX_HOUSES; house++)
    {
        Distance = GetDistanceToHouseOutside(playerid,house);
        if(Distance < 5.0)
        {
            return house;
        }

    {
        Distance = GetDistanceToHouseInside(playerid,house);
        if(Distance < 5.0 && GetPlayerVirtualWorld(playerid) == HouseInfo[house][VirtualWorld])
        {
            return house;
        }

I modified them for my use, I don't have original. Edit this to your version.
