Just coming back into the rental market after owning a home for a short time. I found a place that would be great. Then, I got the lease.

This thing is a nightmare. Here are a few of the greatest hits:

• The lease lists my rent and then says they can charge "additional rent" which is "all added charges, costs, and fees for the duration of this lease." So, sounds like they can just make up a number and add it to the rent and I have to pay it?
• The landlord will make a "good faith effort" to make the apartment available to me when my lease starts. Shouldn't the landlord actually do that, not just make any sort of "effort" to do it, "good faith" or otherwise?
• If the unit is damaged such that I cannot live there while repairs are being made, the landlord "may" issue me a credit for the days I can't live there. What criteria will the landlord use? If they decide not to, that means I'll be paying rent for an apartment I cannot occupy?

This is a short lease — I've seen much longer in my time renting — but even so, I could come up with a dozen more examples like this. What is going on here? I've read the law in the area, and I suspect some of the clauses in here are actually unenforceable. For example, the lease allows for automatic rent increases at lease renewal without notification while the law requires 60 days notification, and it requires me to notify 14 days after notification of a rent increase if I do not accept where the law says I have 30 days to do so.

But how did we get here? I just want to pay a specified amount every month in order to be able to live in a space someone else owns. This should be relatively simple, but it's turned into this weird whack-a-mole game where every lease is a document of all that landlord's past tenant grievances they are trying to now avoid in the future, along with any other unreasonable terms they think they can get away with. Regardless of what the law is, the lease can say anything. If I read it and decline to sign, the next person will probably just sign it and hope for the best.

For those of you who are renting, how do you deal with this sort of stuff? Are there reasonable landlords still out there? Is the right way to buy a home just to escape from unreasonable lease terms, even if you don't really want to own?

Update: Possibly important context- This property is in Philadelphia, Pennsylvania.
