Therefore, I'm focusing on Texas for now.Here are some specific points I would appreciate advice on:Cash Flow and Growth Potential, Market Stability, Property Management, Local Insights.Additionally, if there are any realtors here who specialize in investment properties in these areas and can help me grow my portfolio, please reach out.Thank you in advance for your advice and suggestions.

I understand that investing outside of my local area may require partnering with someone on the ground who has experience and knowledge of the specific market.Once again, thank you both for sharing your valuable perspectives and advice.

Outside of that you can look at crime rates, etc but having a boots on the ground or local expert would be the best benefit of where to look in a specific market.

Specifically, bathrooms/showers/tubs.

Use an attorney for your state, as many states have very specific tenant-landlord laws. 

Advanced Real Estate has a whole department specifically for investor relations.
