Nor have I done an AC system (I typically go for entry-level houses and they don't normally have central AC, which is a little more of a luxury in CT).

There is a lady in this area who is off her rocker that lives in 4 containers, a split level lodged into rock with large windows facing over a river.

Also, for flooring, is luxury vinyl recommended for homes with higher rental price points ($3,000+ a month), or do you stick with engineered woods?

I agree to keep the carpet until it needs replacing, then switch to a luxury vinyl or what ever new product comes out.

Keep an eye on the luxury market.

Luxury apartments and single homes.

We have started building more, but the wrong kind (at least here in Milwaukee it's only luxury homes) and the cost is going up quickly (materials, supply chain.. not only lumber, which has quadrupeld).Demand is comming from a shift in demographics: millennisals are now the largets group of home buyers, 82 million, 39 years old - they are not going back to rent.

Polished concrete floors are nice looking when they are maintained, but I would be reticent to spend on such a luxury for a rental unless it was a higher-end rental.

When oil is booming you’ll see many Craigslist ads for seasonal worker lodging. 

That is a luxury and something else that can fail.
