define your criteria and then talk to brokers and wholesalers who specialize in the area and asset class you are interested in clear vision
in the US: call sellers, some people do it, I have a friend who has a fund and specializes in MHPs in Az and has the list of all the owners whose assets he is interested in and he calls them regularly
websites: I have the disciplin of looking at deals daily on CREXI and also using this tip from one of my mentors: look for commercial properties listed on the websites of residential agents
as I check references from tenants I initiate a rs with a fellow landlord for future purchase
