Renovation 2007: Resale repeated

I’ve heard ‘resale value’ so many times now that I want to make a drinking game out of it, if it weren’t so disrespectful of those speaking, who I know mean well. I have gotten so good pointers and have been challenged, in a good way. But still there is that value that I keeps getting repeated that just seems to undermine my status as a homeowner. Every time someone says something about resale I take it as “hey you are just a renter with a mortgage.”
One of the joys I looked forward to as a homeowner is the possibility of customizing the house to me(without violating any major laws or codes). That drywall, I can tear that out. You know why? ‘Cause I own it. So now I’m all prepped to customize a good portion of the house based on my wants and desires and (most important) budget and I’m supposed to think about some future buyer. The house was designed by crackheads, they didn’t give a rat’s ass about me, why extend the same? What I will do for future owners is do my best to make sure the house is structurally sound. That’s it.
I don’t care about the money. I have too much equity. Because of my income I can only tap into part of the equity. I’d have to sell the house to get the rest. And that is as the house exists now, with no air conditioning, a busted boiler, crappy carpeting, warped floors, and crackadelic design.
One sin against the creed of resale I’m planning is getting rid of the closet in one of the bedrooms. I’ve heard that a bedroom needs to have a closet to legally be called a bedroom. Ok. Stick an armoire in it.
There were a couple anti-resale moves I considered, but decided that the generic solution could be worked around or was more economical. At some point I did play with the idea of not having a single tub in the house and just have a really cool shower. Then I also looked at ductless AC. Decided that if the ducts are on one side the house they can get camouflaged with a certain decorative idea I might do if I can afford it.
