2% is thrown around without the proper clarification it needs, no doubt there. Being in good neighborhoods, good enough that they are at low risk of becoming bad neighborhoods for a long time is top priority for long term buy and hold. Those deals are unlikely to by lying around waiting for new investors.
When looking for 2% in good neighborhoods - "most are found through direct mail, tough digging, great negotiating as well as really good relationships with those that helps find those kinds of deals." I think that's the part of the 2% rule which does not get clarified to people hearing about it for the first time.
With out starting my own direct mail campaign I don't see 2% in a great neighborhood being likely for me as an out of state investor, I shoot for 1.5% but I still have hope of finding a 2% deal eventually. It's a personal goal actually.
When a seasoned investor holds out for 2% in a good neighborhood and eventually gets a property every now and again I don't see how it will keep rents from rising or property values from appreciating.
Then there are those who are comfortable investing in bad neighborhoods and know how to make it work. They should demand 2%, they deserve it for their hard work and the lack of appreciation.
