The old flooring is no longer available, so we are looking at either replacing the flooring in one bedroom with something that doesn't match perfectly , or redoing the flooring in the entire apartment (except the bathroom and kitchen; I already replaced the kitchen floor with a luxury vinyl plank and we have ceramic tile in the bathroom).I would love to get a point of view from other experienced landlords about the possible monthly rent difference and caliber of tenant difference if I had a totally uniform floor in all rooms vs having something different in that one bedroom.

If you are buying a rental in which a few drawers are damaged or missing but the rest of the cabinets are in good shape you can have a local customer cabinet maker recreate to match what you have thus saving you from having to demo the whole kitchen.Its always best to find in stock cabinets for quicker turn around but if you are doing a high end property as flip best to get designed with a custom cabinet maker or someplace like 1800 cabinets.
