Most 1-4 unit real estate investors are using DSCR loans right now for any buy and holds while flippers lean on higher leverage bridge/fix and flip loan options with higher interest rates.

Keep in mind local zoning laws and market conditions in Portland versus Salem—Portland might offer higher rents but stricter regulations, while Salem could provide better cash flow opportunities.Your design approach has proven successful, so continue focusing on appealing upgrades like kitchens and bathrooms, but prioritize cost-effective and durable materials for rentals.

During the hot season all the higher ranking properties get booked so your property has a chance to be exposed to the guests.

Quote from @Garrett Brown: Quote from @John Underwood: Nothing that paying for a 3rd party app to automate functions will fix.If I had to pick something it would be getting higher occupancy rates.Overall things are great.I'm definitely not an app developer so no worries about me making one that can help.

Any way to capitalize on this garage outside of just attracting higher rents once I move out and/or higher sales price if I decide to sell?

A property manager will take the workload off your shoulder but they likely won't get you a higher rent unless your listing is terrible.  

Given your situation, a property closer to Nashville might be more advantageous for short-term rentals like Airbnb, as proximity to a popular city typically attracts more guests and higher rental income.

A higher CTR tells Airbnb’s algorithm your listing is engaging, which improves your ranking, increases visibility, and leads to more bookings.With the rise of professional photography, simply having high-quality photos isn’t enough anymore.

That being said, with interest rates being higher now, I may not be able to find a turnkey property that makes financial sense.  

Direct bookings results in higher revenue.
