You are doing such a good job!
In the end, it's you and your kiddo who are going to benefit from all this hard work, more than your landlord! It sucks to have to do it all at once like this, but once the inspection is over you'll be able to enjoy your newly cleaned, organized space. Sometimes it just takes a huge event to get rolling, YK? For me, it was an impending visit from the MIL.
After this is all over, you will probably even be glad that it happened, because of what you'll be left with.
Keep up the momentum, you're amazing!
