I need to select the top 3 distinct from the below stored procedure rather than the top 3, how do I do this?

SELECT top 3 tb_specialoffer.*, dbo.tb_properties.*, tb_counties.*, tb_regions.*, tb_country.*, tb_town.*, tb_photos.* FROM tb_specialoffer INNER JOIN
dbo.tb_properties ON dbo.TB_specialoffer.so_bnbid = dbo.tb_properties.PropertyID INNER JOIN
dbo.tb_counties ON dbo.tb_properties.Prop_County = dbo.tb_counties.county_id INNER JOIN
dbo.tb_regions ON dbo.tb_counties.region_id = dbo.tb_regions.RegionID INNER JOIN
dbo.tb_country ON dbo.tb_regions.Region_Country = dbo.tb_country.CountryID INNER JOIN
dbo.tb_photos ON dbo.tb_properties.PropertyID = dbo.tb_photos.propertyid INNER JOIN
tb_town ON tb_town.town_id = prop_town
WHERE dbo.tb_photos.main_photo = 1 AND town_approved = 1 and tb_properties.prop_visible = 1 and tb_specialoffer.so_start <current_timestamp and tb_specialoffer.so_end > current_timestamp

unambiguously distinct *,*,*,*,*,*,*

No, you're never too old to Yak'n'Roll if you're too young to die.

you mean distinct of entire value combination or distinct of any 1 field?

Sorry I should have been more clearer.

I need to find a distinct value of tb_properties.propertyid. All methods I tried I end up with unambiguously distinct

then you should decide what values you need to bring along with this distinct propertyid from other fields. you need to apply some aggregation like min,max,sum,... for others

SELECT DISTINCT tb_properties.propertyid

FROM tb_specialoffer INNER JOIN
dbo.tb_properties ON dbo.TB_specialoffer.so_bnbid = dbo.tb_properties.PropertyID INNER JOIN
dbo.tb_counties ON dbo.tb_properties.Prop_County = dbo.tb_counties.county_id INNER JOIN
dbo.tb_regions ON dbo.tb_counties.region_id = dbo.tb_regions.RegionID INNER JOIN
dbo.tb_country ON dbo.tb_regions.Region_Country = dbo.tb_country.CountryID INNER JOIN
dbo.tb_photos ON dbo.tb_properties.PropertyID = dbo.tb_photos.propertyid INNER JOIN
tb_town ON tb_town.town_id = prop_town
WHERE dbo.tb_photos.main_photo = 1 AND town_approved = 1 and tb_properties.prop_visible = 1 and tb_specialoffer.so_start <current_timestamp and tb_specialoffer.so_end > current_timestamp
