Finish work for Two Strategies

[Daniel Vallejo]

Hi Everyone, 

I am currently working on converting my Garage into an ADU of 450 sqft. The space has already been permitted to be an extension to the living room back in 1984. Now I'm closing that off and creating a 1B/1B. My question is in regards to the type of finish work I should go with to be able to execute two strategies efficiently in case one fails. I'd prefer to go the short term rental route, but if for some reason the property doesn't perform well as STR I'll go the long term rental route. Kitchen - Countertops - Showers/bathrooms - Flooring - what finishes can I use that will maximize my cashflow for STR but will not break the bank in case LTR strategy must be implemented?

First time posting here, so thank you for your time and help!
