I rent homes unfinished for the most part but sometimes, if a space would look better with something extra, like a coffee bar or a patio table, I will pick one up.

Most flippers will only add the ADU if there is already under utilized living space (not garage conversions but craft rooms, bunk house, etc) to convert.  

It also has become a popular travel destination over the last 5 years or so, so there has been an increase in competition in the STR space as well. 

The dishwasher should be to the right of the sink as a large majority of people are right handed.There is a picture of a second fridge in the kitchen, but no mention of it in the listing.You'd have been better off putting the stove where the second fridge is and giving the renter more countertop space. 

Quote from @Marc Shin: Look underneath it (crawl space, basement).

I'm in the messy middle as a residential agent who works mostly with investors and specializes in the small MF space.  

Does their collective business occupy one of the spaces in the building? 

You have lots of other choices in the free and paid space. 

When you're responsible for customizing the layout you can get more creative and find extra space a builder missed out on because they wanted to include some type of flex space or amenity room or it just didn't fit their box.

After 8 years as a director in the kitchen and bath retail space, I'm bringing my positive energy and relationship building to a wholesaling firm covering Los Angeles and San Diego counties (we specialize in single family homes priced between $400-$1.7M).
