Craigslist. Garage and estate sales. My B&B microwave is nicer than than mine, and it was $20 at a moving sale, and my Keurig cost $15.
My advice would be to start moving stuff that you don’t use all the time at your current house to the new one as soon as you close.
Beds should be queen size at least. You need 4 pillows for every bed, and 3 sets of linens for the entire place — 1 in place, one being washed, and one for emergencies/backup which should be locked away from guests. I won’t get into colors or not, but I have always had all white sheets and pillowcases from Amazon and white towels from Costco.
Colored linens can get bleached by some makeup & acne treatments that contain peroxides, and I find it easier to get stains out of white than deal with ruined colored items. There have been long argument threads in this forum on this topic, so I’ve said more than enough.
My Craftsman rooms are furnished with relatively spartan Ikea Tarva bed frames and night stands, because I wanted to faux paint them to match the stain in my fir woodwork. Mattresses were ordered via Amazon, and are fine after 2 seasons. I’ve been trying out all the beds during closure.
You may get remote workers, so high speed internet and a decent desk space with good lighting and a comfortable chair is a necessity.
If you have a remote rental you MUST have outside cameras that you can view remotely, and Air requires that you disclose their existence in your listing. If you search the forum you will see why you need them.
You also need to have a basic maintenance toolkit there — big & little crescent wrenches, screwdrivers, hammer, pliers, pipe wrenches, electric outlet tester, as well as vacuum(s), mops, brooms, etc.
My next amenity purchase will be to replace the current garage sale lamps on the Ikea nightstands with new ones that have USB and electrical sockets in the base. Less hassling with extension cords, which can trap the robovac that’s only there during turnovers. No dust bunnies under the beds!
