Too many variables, especially as to behavior of renter or buyer.
From college through my salaried years before going on my own as a private consultant (still sweating remembering the level of risk and bravado) I rented and lived in 7 different locations. One was a steal (1/8 cost of dorm room and board) because was in an extremely crime ridden part of Cambridge, Massachusetts (this was long long long ago) and I knew how to create very effective electro-mechanical crime deterrence. It was cheap, cosy, convenient to classes at MIT and Harvard, and utterly safe as I used it.
Second was my first boarding house. Third was my gigantic firetrap extremely profitable 2nd boarding house, for which the crux was I had to find the drunken landlord (I knew every Irish bar in Somerville) every late mid-month so that on the last Friday of the month he could soberly bribe the city building inspector to not condemn the whole damn firetrap mess. Fourth rental was the size of a walk in closet, but up on a hill overlooking my favorite California surfing spot, and only a 5 mile bikeride from work. Fifth was market price, but with a swimming pool and oodles of the tenants were airline stewardesses who, uhm, shared their entries from little black books of hot needy men (I only lasted six months there). Sixth was an absurdly gigantic badly designed “owners unit” in an apartment complex I got for cheap by also maintaining the pool while wearing speedos and boarding the two idiot dogs of the owners in the up the stairs 2nd bedroom.
Every home I have bought (5 so far), I bought with a business plan taking into account
1 location*,
2 sufficient obviously difficult for most but easy for me horrid problems needing remedies**,
3 financing mortgage plan,
4 selling/rental plan.
Homes for me have always been investments first and places to live second (no kids makes it easier).
I have done splendidly, but few people can do what I do as to architectural/engineering comprehension, DIY remediation, and predicting urban RE trends. From conversations with others I know there is a huge wide spectrum across all kinds of other strategies with similar specific details bearing on the rent buy question.
The crux, never think of housing as a “given” or you will be taken.

*location, location, location LOL My very best was this house, the oldest (built in 1923) house, and closest while most isolated from tourists hordes of the fabled neighborhood under the Hollywood sign. Its location was perfect, but when I bought it was literally collapsing from idiot remodels and neglect.
**Collapsing structures I knew how to jack up and repair, electrical circuits and breakers and plumbing dated waaaay back around WWI I knew how to bring into modern times, and hideous interiors I knew the right queens who would do a redesign I paid for materials and they’d do just “for the fun of it”.
