@Ali Boone I am going to have to disagree with your summation of Texas markets. I can't speak for all the Texas markets but here in San Antonio, it's very easy to net $300+ per month cash flow on SFRs. Yes, there are higher real estate taxes than some other markets (I own properties in St. Louis as well), but the demand for rentals here is much greater than other places. I have never had to advertise my rentals; word of mouth has keep then 100% leased over the 2-year period I have been here. My experience is not unique. My client's won't buy SFRs for rentals if they can't achieve at least $300/month cash flow. Typically this is a true net of $300/month accounting acquisition & renovation with a hard money lender, a refinance into a conforming loan, real estate taxes, water, and a property manager.
They keys to solid cash-flow in SA is buying in the right locations, and purchasing at the right price. By close to Downtown (Southtown, Tobin Hill, Beacon Hill, Government Hill, Laurel Heights, Monte Vista, Mahncke Park, etc.) and you have high demand, qualified renters, and a property that will continue to appreciate. Of course this isn't the only place to make money on single-family rentals in SA. On the East and Westsides properties can be purchased extremely inexpensively. Not all areas are "warzones" as many would like to believe, and working with Section 8 or San Antonio Housing Authority (SAHA) can guarantee rents. The areas I have mentioned don't even begin to cover all the neighborhoods that you can achieve solid positive cash flow.
Lastly, Here are few things to consider when looking at the SA market for a buy-and-hold strategy. San Antonio is home to over 18 colleges and universities, 4 military bases, 2 major medical centers, and large employers like Toyota and USAA. It also has one of the fastest growing populations in the United States, growing more rapidly than Austin since the 2010 census, and almost as fast as Houston. San Antonio is also the first major city across the US/Mexican border and has very large documented and undocumented immigration population. Needless to say these people need a place to live, and most of them will rent.
