The list of houses are as follows not inlcuding a potential one in alabastra (since I have just arrived)
Canneroc, Adessa, Motus Mining, Rathir, House of Valor, Seawatch,
All of the stashes are 100% connected. You do not get separate stashes thus the 155 item limit carries to each house. Canneroc is actually the easiest house to fast travel too. Rathir, Adessa, House of Valor, and Motus mining all offer gold opportunities. Canneroc regularly receives shipments of a product that can be sold. Seawatch has the most valuable items form chests, etc,... and is probably the toughest given you have to recruit members to complete it.
edit:
SeaWatch also provides an alch trainer if you complete the necessary task.
I haven't encountered a lot of information about additional houses beyond the first one you get in Canneroc (Gossamer's End) which you can expand at the blacksmith and stay local to all the town services.
Your question seems to be more focused on the stash that the house gives you and it turns out that they're not necessarily connectect.
So far my list of points where you can access your stash from is
- Canneroc: Must complete "A Tangled Web" quest
- Adessa, the Walls: Will trigger when you arrive at the southern Apotyre destination
- Motus Mining Outpost: Not sure, have only read about this one
- Rathir: Rumoured at this point, I haven't good evidence of it
