The two are almost entirely different markets in terms of price points, returns, tenant quality, and overall investing strategy.

.: Does anyone have any information about the short term rental market in Kyle Texas?

What strategies have worked best for marketing midterm rentals in secondary or smaller markets like Portsmouth?

I would keep it at "reasonable market rent" (whatever that means).

Are they at market rent, or locked into below-market rates?

There is no one size fits all answer for this question, market to market, and property to property are all different. 

Lots of opportunity to find mismanaged multis as well where the older mom and pop landlord has rents way below market and can come in and increase NOI just by getting units up to market rent and maybe doing some cosmetic rehabs as tenants move out.Value add multi is what I prefer and think works best here but that's with me being here boots on the ground and being more active with it.

@Nick ConnorsIt’s great that you’re using your savings to invest early, and Columbus could be a solid market given your familiarity.

What marketing efforts are they going to do outside of just posting in the MLS.

If you have a lot of family in OK, that can be a great place to start assessing since you have dedicated boots on the ground, as well as a reason to visit.Don't overthink the analyzing of markets when you are still figuring things out.
