Interior photos cover everything inside the property. How to prepare for inside is clean everything from windows to floors.
Kitchen- Simple is best. Put all small appliances in cupboards. Keep it bare. Less is best
Living rooms- organize furniture to make room look bigger. avoid the couch in the middle of the room.
Bathrooms- take all soaps and bottles off shower and sinks. Close toilet Lid
Bedrooms- Make bed, stuff everything else in closets :)
