Thoughts on buying a 4-plex thats currently R1 zoned ?

[Solome Ejigu]

Hi BP! So, I have found an off market fourplex but its currently zoned for a SFH (R1). There is a big city centre plan thats been happening and zonings are changing. There is a housing crisis and the city is getting dense, low supply high demand. My question is should I still go for this 4plex despite the zoning? There is potential it could change in the future with the city plan, I could try to get a legal non-conforming letter from the city if its applicable and/or try to rezone it but what if I'm not approved? Is it worth the risk? Anyone experience this? how did you troubleshoot?
