In your case, it won't. You would be better off renting and investing the extra $2k in assets that are productive rather than speculative. This should be obvious, but the West as a whole has bought into the housing as a form of wealth and can't let the music stop now without ruining millions of lives.

Housing as a form of generational wealth is a trick that works for the population as a whole for a generation or two. The majority of rentals come from regular people who bought long before you and have significantly lower mortgages or no mortgages at all, or large firms who have access to lower rates and more accounting tricks like depreciation. In either case, what they can afford to accept as rents is a lot less than what you can afford to accept as rent. The best you can hope for is significant appreciation or significant rent increases in the face of stagnant wages. High demand markets like NYC and SF can sustain ever increasing prices for a long time, but most markets cannot.
