investment RE must cash flow, cash flow and cash flow

while traditional RE is more focus at location, location and location, I think investment RE must focus on cash flow, cash flow and cash flow.

many ppl here more interest in utra high appreciation in RE and sacrify with negative cash flow, they need to relearn the truth of RE investing in a long term market.

RE investors need to look at how to minimize upfront cash investment, and maximize positive cash flow, providing a consistant cash income and appreciation over time, nothing beats $0 investment but with 150k cash income and 300k appreciation each year.
