Some suggestions....
1. Get your quality subs lined out. You will need demo, flooring, electrical, plumbing, cabinets/counters, and painting/finishing.
2. If the layout works than stick with it and don't try to get too creative. Repeat.... don't be creative! The only exception would be for high end homes.
3. Measure the kitchen and take it do a good cabinets and countertop shop (not a big box). You can get much better pricing and quality from non-big box stores. Have them layout the space. Double check it but trust their judgement on layout.... They likely know more than you. Tell them you are an investor and you can sometimes get a wholesale discount (if they think they will get repeat business).
4. Take the cabinet design and determine your lighting and plumbing layouts (hopefully this remains the same, but this is the time to do it if necessary).
5. Proceed in this order... Demo, electrical/plumbing, flooring, cabinets counters, and then painting/finishing. I would highly suggest hiring the cabinet company to install the cabinets and counters. I've found that they are usually cost competitive (maybe a little more), but there is a lot of liability transfer when they have full A-Z responsibility for design and construction.
6. I would almost always suggest new cabinets if you have even the slightest question as to if you should refinish. I've seen too many people be penny wise pound foolish on refinishing cabinets. In any rentals I would suggest granite. In higher end flips you would likely need to upgrade. Granite should always be the default (no laminate) even in low end homes. Granite costs are reasonably competitive to laminate and it is (a) indestructible, and (b) will likely get you a higher rent or quicker occupancy.
Good luck.
