Hello - To kick it off, if you could buy multiple 80k properties and gross 1k/month positive cash flow after expenses count me in! That sounds incredible. We are closing next week on a place in general Minneapolis area that will be around $300 positive/month and that sounded very good.
Personally after a couple purchases now, we prefer the monthly cash flow over appreciation. Appreciation is great and can be extremely beneficial in the long term through the ebbs and flows of market flux etc but it is the cash flow that will allow you to take addition risks in the short term. Without it at least for most people, coming up with that next down payment is extremely tough.
Aaron - we have used that rule ourselves, I've heard it isn't the wisest thing because you can tend to limit yourself of opportunities but after moving between a few states and a couple of home purchases when we buy rentals we like to have them as a "fall back" per say if we were to come back to the area and want to live in something while finding another house, we would need it to be functional and nice enough for ourselves in order to purchase.
