There are some things we will "Opt out" of like factory installed granite & flooring.

There is a mini wall and doorframe on the right side, when facing the fridge, and kitchen cabinets to the left with new granite countertops.

Paint dated blonde cabinets white, granite-look laminate or some cheaper solid surface counters, LVP floors.

And more granite!

You have many benefits Lower pricesLower loan term lengths 0.12% - 0.18% cap ratesSections 8 (depending on what you like)Rental Quality Rehab(lower income areas do not demand granite counters and cherry cabinets)Now if you invest now only to use it as a retirement vehicle then something middle class that will appreciate over time or will allow you to sell for a nice gain in the future then this area is not for you. some mindsets think $150 cash flow not for $500 in a few years and others think $150 cash flow now for $50,000 in equity in a few years.

No increase in water cost, but a $50 bump in rent; that plus granite counters (one 9' prefab slab does entire apt, so $250+ installer cost) means I charge at upper end of comps and rent quickly and can be picky. 

Not trendy, just light and fresh and warm.But, if otherwise everything is functional and clean and not god-awful, you should be fine - assuming you're not in a really rich trendy area that absolutely demands granite countertops. 

Study the Realtor listings and note down the advantages of the home that the Realtor or agent  is listing - you will see a pattern - Realtors know what sells in that price point and you can glean a lot of helpful information about marketing from being familiar with them.The other thing that I would say is try to get a feel for the materials used in the higher end homes and include at least one of those if you can - feature walls, subway tile, a granite island top if you don't want to kit out the whole kitchen etc.

Do they offer granite/quartz counter tops and updated appliances? 

And I love the light colored granite and the fact that you didn't paint everything gray.
