@Sean Ray I'll give you my perspective as a newbie, which is possibly less wise than some of the other advice you have been given, but possibly from a vantage point closer to your own.
I've been actively looking in DFW for the past 6 months or so, and am finally under contract on a home. It is a >1% deal on purchase price, but including all the rehab needed it will be a ~0.9-0.95% home. The reason I am okay with it is that it is in a B+/A- neighborhood, not the best ISD, but feeds the best schools in that ISD. It is on the small to average side for square footage, so fits in the neighborhood well. It needs enough work that retail buyers want no part, but not so much it's overwhelming. It isn't directly in the path of growth, so I don't feel the neighborhood has been run up as much as many in the Plano/Allen/Frisco areas, but is only a ~15-25 minute drive from much of the new corporate developments in the Plano area. In the end, I feel safer with my likely tenant pool in this neighborhood than in the neighborhoods I could actually find a 1% deal in.
In my (very conservative) analysis, this is a slightly negative cash flow property (like $10-50/mo) - but my costs estimates are usually way higher than just about everyone else I see on BP (I leave room for 65-70% of gross rents in expenses).
I, like you and some other posters, am somewhat nervous that we are closer to the peak of a cycle than the trough. However, I am better at predicting myself than markets, and I know that if I always worry about market cycles, contractions, or apocalyptic events I'll end up going home and just reading forums instead of actually getting in the game. If your plan is to slowly acquire properties over a long time horizon, go ahead and get started - just do it conservatively. At the end of the day, I can be afraid of the cycle - or I can get started and see how things pan out.
