Buying in current markets

[Brian Christensen]

hello, I am new to BP and am about to sell one of my two rentals for a profit. I bought in 2004 and can cash in on equity; however I am rather Leary about current market conditions and I see many bubbles bursting like they did in 2008. I want to use the cash from the sale and buy more RE however am getting skiddish. Any thought? Is it all about cash flow? How do I buy in this market?
