Good morning Gabe.
Del Rio is a great market, there are few young active investors. We own multiple duplexes in Del Rio, some were remodels, another was new construction, where we managed the construction. My advice as an investor focus on your investment strategy, Will you rehab, flip, buy and hold etc.? Make sure you know your WHY and don't deviate from your goal.
Regarding finding local contractors, there are plenty of trade subcontractors. In Texas, electrical, plumbing, HVAC are licensed by the state and carry general liability insurance in order to mainatain their license. I would reach out and meet the city building inspectors and ask specific questions regarding whose work they inspect that result in minor or no isssues. Eventhough city inspectors can not endorse specific subs you will obtain valuable feedback.
If you are looking for a handyman, there are also plenty. If you build a working relationship with subs or handymen and treat them with respect you are ensured success. Most of the fears or nightmares described in podcasts or books are just a description of their experience not doing their fue dillegence.
On a final thought feel free to reach out, I enjoy a Venti soy milk latte.
