I use coil top stoves. Generally Tappan, white/black color. Always self-cleaning. Gas is better for cooking, but rental kids sometimes turn the gas on by mistake. They run $325 or so.
White 18.2 CuFt Frigidaire refrigerators. Top freezer, Absolutely NO ice makers. Frigidaire appliances are generally bottom of the barrel, but are pretty cheap. Cheaper to replace than repair. That's what you need in a rental. New ones are clean and ready to go. They run $450-$550.
Dishwashers are always ~$300, with a food grinder. Always white, unless I get a deal on a different color. Generally Whirlpool or Maytag. Sometimes GE. Skip Frigidaire on a D/W. All mine have plug-ins for electric (not hard-wired), and their own water shutoff.
I get almost all my appliances from Lowe's. Free pickup and delivery. I buy them on sale when I can, and get a 10% coupon off eBay to save another 10%. The coupons cost ~$2.00. Of you can get a Lowe's credit card and save 5%. Or a military 10% discount. Or ask for a discount and you can generally get it.
I generally do not buy used appliances, as I do not want to run around all over trying to find clean appliances. And I do not want to deliver them either. And I certainly do not want to drive to a place to get an appliance, and decide it's not worth the price and have to drive back.
I am in a class A area, and have class A/B tenants in my apartments/duplexes. These appliances work for me. If you are in a C/D area, maybe used appliances are better.
Paint is Sherwin Williams. Semi-glass all the way, ceilings, walls, trim. I get my paint at ~50% off list. At HD, you can use the pro-rewards and get 25% off Behr Paint. I use interactive cream for my color and white trim and ceilings.
