Overall, Section 8 is a good way to get some pretty reliable income to get the property cash-flowing, provide additional experience, as well as with the required annual inspections, make sure your property stays in a good condition! 

With your experience and possible skillset, perhaps finding a company to sponsor you for a green card may be a better option? 

I wanted to see if anyone has experience with or owns any properties with knob and tube wiring and what I should do.

Worst contractor experience I've ever had.I then hired a second remediator.

My day job is being a financial professional, so I have good experience with underwriting and sales that I believe can be translated to real estate.

Your decades of experience have made you jaded. 

Now you are saying you have no experience owning/operating an STR, that's another hit.  

That's the first question as real estate is like another job and if you are upgrading properties it's like running a daycare. also what experience do you have?

Does anyone hear have any experience with either of these companies? 

I've had a positive experience.
