Jeromy,
Since you are from Houston, do you have family or friends there that could help you? Even though they may not be RE trained - someone you can trust to be honest and put their eyes on things to give you feedback?
I have been successful in local SFR investing, but doing SUCCESSFUL investing remotely is a whole higher level IMHO. Your ecomonic importance to any of the core 4 will be so low that getting quality attention will be difficult at best.
Let me give you a couple of examples. First, I have called Property Managers listing properties for rent and left messages and they never called me back. Then I list my property nearby and it rents within 2 or 3 weeks. 2 months later I see the property I called about still advertised for lease. Of course it costs the PM nothing to sit vacant and eventually they may find a tenant so they can "double end" and make twice the commission than they would make on following up on a phone lead from another agent. Meanwhile, I paid no commissions and had only a couple weeks or 1 month of vacancy because I was motivated to get make ready, showings and releasing done quickly. Assuming your investment purchase criteria is sound, vacancy is often the biggest factor to determine a property's profitability. Depending on a PM or RE agent for this will be costly.
Second, finding good properties using a RE agent is more than difficult. Lifestyles Unlimited teaches students to find 20 RE agents and maintain 20 agents simultaneously to scout for properties. Why? To increase the difficult odds of finding a good property using RE agents whose bread and butter money generators are cunsumers who pay full retail prices for everything. That is not what a talented investor is. If you pay retail price your likelihood of success is low.
I've not had a single house in 70 purchases brought to me by a RE agent. Wouldn't they be smarter to 1) take a good deal themselves 2) take it to family or a friend 3) take it to known quick cash buyer that takes little (hand holding) work?
I wish you the best and success is possible, but the cards are stacked....
