I’m not knowledgeable on the Kelowna market.
But It would totally depend on what you want yourself.
For me, owning 2 bed/1 bath units as well as 3 bed/2 bath, I find the competition in 2 bed units high
In most cases the majority of rentals are in that segment. The advantage on the other hand is that in general you get, or would allow, working single or working couples and the wear and tear is minimal.
Due to competition in that segment you really want to make sure your product stands out.
It seems in the 3 bed Apartments/townhouse segment, the rental inventory is lower and you can position yourself very well between that 2 bed unit and the 3 bed and up single Family house segment.
Advantage is collecting high rents, but expect to have young family apply and 3 to 4 people occupying the space with as a result a tad higher wear and tear.
Personally I would probably prefer to find x2 props due to drawing form a larger rental pool, but that’s not to say SFH in higher segment is bad
Hope this helps a bit.
