Rent controls do sometimes specify how much rent can be raised year over year. Drop it too low one year, be stuck with relatively low prices in the short term.
I don't live in the bay area and pay half the rent for three times the space in Boston... not exactly a small town... the Bay Area was already unattractive for me financially and I have an advanced degree in an engineering field.
Your effective rent _did_ drop, but landlords did it by offering 2-3 months of free rent on a one-year lease (with old rates applying.) It doesn't take Nostradamus to see what happens in 12 months: maximum allowed rent increase and no more sweetheart deals, meaning an effective increase of like 35% (or move again to try and get another deal somewhere else.)
It wasn't worth it to me, so now I'm paying less than half my previous rent for around 2x as much space in SLC.
