Specialize in subject to?

[Josh Morris]

Has anyone on here ever specialize in subject to? Would it be a good strategy to take over mortgages of overs instead of owner to finance? Also when/If you specialized in this way of buying real estate for long term, what was your way of sourcing leads? I thought of making the yellow letters for people and just taking over mortgages, but it seems like a old and ineffective method for my market. Thanks. ☺️🙏
