Sherman or perhaps between McKinney and Sherman.SaginawBurlesonCertain other locations if you can find the right rent/price.

My 46 years in the real property investment field has taught me that almost all wealth in real estate is accumulated through price appreciation of the subject property owned and amortization of the associated mortgage note(s).  

I think the higher price agent is better.

Slowly work your way up to bigger purchase price and rehab budgets.

I stopped at the "right" part.You need to start interviewing PMs in Austin, getting a feel for prices to renovate(hvac, water heater, floors for material + labor, etc.).

Quote from @Micheal Smoke: Hi, my name is Mike Smoke, and I'm an aspiring real estate investor focusing on multifamily and Section 8 properties in the U.S. as the barrier to entry is much much lower in terms of price compared to Canada and Funding options. 

Numbers are the following - purchase price $120,000, rehab $75,000, ARV $250-265,000.

Real life absolutely no one will give away on the internet their investor friendly priced good contractors. 

If you have a truly superior and/or unique product it will be easier to not have to compete with price. 

The only two ways to rectify this are (1) purchase the property far below market price or (2) significantly increase the property net income usually through some method of “repositioning”.
