If you use Incognito's streamer, then you can create dynamic areas around the houses and when somebody is close enough, have the textdraw displayed,

https://github.com/samp-incognito/sa...wiki/Callbacks
OnPlayerEnterDynamicArea(playerid, areaid)
OnPlayerLeaveDynamicArea(playerid, areaid)

https://github.com/samp-incognito/sa...Natives-(Areas)

or

If you have house pickups, then show the textdraw when a player picks up the pickup (OnPlayerPickUpPickup).
