“Washing the walls. We just finished painting the living room and step one was washing the walls. It took me almost six hours to do the whole thing (it’s a good sized room and I went over it a few times to get it as clean as possible), but it looked so much better! Cost is free, minus the time and I guess technically water and soap. Obviously painting changed the overall look and wasn’t super expensive (~$50 per can for the color we bought), but I wouldn’t call it the biggest bang for our buck out of the whole process.”

“The other thing that made an insane difference was patching hairline cracks at the ceilings of outer walls. The house is 100 years old and the previous owner let issues build rather than making improvements little by little. As part of our painting preparations, I used some type of spackle/putty situation to fill them in and smooth them out. The stuff we bought was less than $20 and we still have maybe 75% of it left.”
