The positive experience you're family had in Berbera is replicated throughout Somaliland.In 1991 my Awoowe's villa in booli qaran was taken (after it was destroyed of course) by the mightiest Somali clan, Hawiye.
Some of my other clan members owned properties in Berbera. After things went back to normal some were claimed by it's rightful owners and some are still guarded by an Isaaq elder to this day (last time I was updated on that was in 2016 not sure if he is alive now) SL also. Moreover; Warsangali/ugaaslabe had the ministry of defense even though we only make up up to 3% of the population. That would've never happened in the south. That's the difference between the internationally admired Somaliland and Somalia.
To be fair though, I am distantly related to a very wealthy landowner who had multiple properties in Muqdisho, including businesses. He passed in the early 90's but when his sons went to Muqdisho years later, they found that the local Hawiye had not only evicted squatters and looters from pretty much every property, they had actually set aside some of the business takings for the owners family should they ever come back.
Having spoken to Landers who had property in the south, that is actually not as much of an isolated story. Granted these are all Isaaq's and I understand the stories might be very different if they were from clans with whom the local population warred with.
