Great questions and answers all, lots of good information. My take away from this discussion and from listening to about 1/2 of the podcasts since joining a few weeks ago is to buy as smart as you can (don't overpay), and even if the market tanks in the worse case you possibly could be underwater for a period of time but in buy and hold scenarios the outlook should be long-term anyway. And in buying smart you also use conservative estimates for expenses and rental income and with positive cash flow your investment will pay off both in the short run and in the long run while you build equity. As long as you hold the asset and maintain positive cash flow the investment will pay off. So as I have heard many times here appreciation is icing on the cake for buy and hold strategies, positive cash flow and building equity is the basis for the investment.
Thanks for starting the thread @Jeffrey Lester , it's very impressive to hear all of the stories of young RE investors, best of luck!
