We do 100% urban mid-high rise and hardly have any floor plans with space for dining room tables... and no one objects.

I'm going with a dolly island. it's on casters ( or dolly wheels ) opens the space up nicely and you move it around. Islands are only nice when they have a drain or an outlet

I like dining tables because it seems so much more closeness when you have friends or family over for a meal....

I was regional over 3 luxury high rise buildings in Atlanta. Younger demographic. We had several floor plans and the first ones to lease were the ones with an island.

it sounds like you have a great grasp on who your target renter is. Have you considered running a targeted ad on FB/IG toward that audience? Using a poll or send them to a landing page that shows them the two options and allows them to vote? You could set up the conversions to fire on their vote click and send them to a thank you page featuring your new property. Allows you to get feedback you’re looking for from your target audience while also creating awareness about the project!

I am a new construction mid rise in Houston Texas. I have a 2 bedroom that has a 14 foot Island and no dining room space. I've leased them all and what is blowing my mind is that almost all of my applicants had dining room tables. Several sold them and the few that didn't, rented a storage space from me.
