Better to let the money sit under your mattress.....

Getting mattresses, couches and other large items picked up is expensive.If you caulked holes from the tv installation, it sounds like the patches were done incorrectly and will need to be redone.

Buying with cash doesn't mean saving your money under your mattress until you have enough to pay cash for a rental property.

Describe each room with LONG descriptions with tons of details like mattress type, kitchen gadgets, bedding quality, etc...Turn on smart pricing, get on multiple OTAs with a channel managerHow long is your description?
