I would recommend considering conventional financing until you reach Fannie Mae's limit of 10 properties, then consider either a portfolio loan, and start your race to 10 again, or look at DSCR at that time. 

That said, I highly recommend speaking with a local professional in the DFW area to get insights tailored to your specific goals.

Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?

@Wiley Hood to be honest, with all the new regulations around documentation for cost segregation that has come out, I recommend having a professional do them.

Having a long-term rental while living abroad is do-able.Flipping houses while abroad, in my opinion, more difficult, especially if its your first go around with real estate.I would recommend taking a flight and staying in the area for a week and inspect the neighborhoods and make connections.You can reach out to @Elenis Camargo who has a PM company in Jacksonville.Best of luck though.

Are there any resources that you'd recommend?

If you're working with an investment brokerage, I'd recommend tapping into Tampa and Central Florida markets too—areas like Riverview, Wesley Chapel, and Brandon have been strong for both flips and long-term holds with steady demand.

I have my own properties throughout the area, and have worked with many contractors, PMs, lenders, insurers and attorneys that I can recommend.

I recommend them when they are appropriate as any good agent should.

be sure to stick to your 70% rule for the flip, know your numbers. run everything conservatively. overbudget for time and costs but 15-20% Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?
