We have similar size units (256 square feet.) We did basic updates over the years and then said...time to do it right.
We bought stock home depot cabinets and counter tops. Just a few top cabinets to anchor open shelving (looks more spacious.) L-shaped kitchen.
An IKEA sink was the right size without being overwhelming. We got rid of old stoves and put in two-burner cook-tops and (easily replaceable) counter-top convection ovens, the largest we could find (Oster XL - holds regular 9x12 pans and available at Walmart.) Added a good microwave. Under-cabinet lights. Ceiling fans.
The kitchen is functional and COULD cook a larger dinner, but in that space no one is doing that, so what is there works great for the (single) tenants.
DH dismantled the old closet and built one with lots of shelving and two hanging bars. Heavy curtains to cover to save floor space (no door.) The curtains are hung from galvanized pipe hung from the ceiling: industrial chic ;)
A new vanity, commode and medicine chest - nothing fancy at all. Couldn't replace the tub so we changed out shower-head, added curved shower curtain rods and storage behind bathroom doors.
Finally new paint throughout in light grey with white woodwork, and Allure flooring throughout to make it open - nothing to break up the flow.
They now look just lovely and they stay rented, with people begging to get one. We raised the rent from $625 to $725 per month and could probably have gone higher.
Also, for me the point is that I do not feel I need to apologize or say, "It is what it is..." They look great and people know this. They attract good tenants! --184.188.xxx.xx
