I have owned rental properties in the Utah Market for 10 years, bought high, but never sold (so through the one of the worst downturns of our time). I only owned one investment at that time, AND I had that particular property on a 15 year amortization, I still cash flowed on that property about $90/ month through the whole economic crisis. I think if you are smart in the area and property you invest in, even in an economic downturn you will be just fine on cash flow. Take into account what @William Hochstedler and @Jeremiah Maughan have said though. Those are very realistic numbers, very close to what I have been seeing in our current market. I use 35% on older homes and closer to 22-25% on new and freshly rehabbed, depending on in major things in the property have been replaced or dealt with ( roof, HVAC, Electrical, plumbing etc.) I know those prob seem a little high, but I am also quite conservative, so I want to be sure my numbers will always work, no matter the market! Best of luck, I would love to hear updates to your story!
