Gut and update the kitchen now. Remove the existing cabinets intact if possible. Sell those for $200 on craigslist. Sell the double oven and fridge for $200 on craigslist. Put the new 36" fridge where the old double-oven was. 24" wide base cabinet where the old fridge was. To the left of that, put the new electric stove (need to have >15" counter space on either side of a cooktop). Install an over the stove microwave. To the left of that put the new dishwasher. Left of that will be the sink with shiny new faucet. Fill-in with corner cabinet, etc.
New cabinets $2000.
New SS dishwasher and microwave $700.
Used SS fridge and stove $1000.
New granite counter top $800.
Sink, faucet $500.
You'll be all-in for $5k. After tax deductions, you'll be at $3.5k (consult your tax pro). Raise rent $200/mo. (ROI ~= 40%) The improvement will pay for itself in 2 years and the property value will increase >$10k.
...that assessment is fairly unrealistic but might be worth consideration.
