I know this is about an owned house (that you should be touching up and repainting the walls of before reselling anyway???) but for ppl who are paranoid about putting holes in rental walls: don’t be.
Put up posters. Shelving if you need it. Have hanging plants. Invest in a studfinder. Spackle kits are cheap and everywhere now, or you can use white toothpaste, glue, or even soft air-dry clay to fill holes.
Scuffs and rub marks are considered normal wear and tear and landlords can’t charge you for them. Most places will have you fill holes but will have to repaint between tenants anyway, so even if the spackle doesn’t match the walls, it’s not a big deal. Check your state laws about what is considered normal wear and tear. Most states have laws covering everything from paint to flooring. For instance, in my state, carpet that is 3+ years old is considered past its normal life cycle and therefore any damage to it cannot be charged for because the landlord/management is expected to put in new carpeting.
Before any move-out, check local laws considering paint, flooring, light fixtures, appliances, etc. Landlords and management companies make BANK on people not knowing that they’re paying for paint rubs that they’re painting over anyway and carpet that has been paid for 6 times over.
