BRRRING in BC - Purchasing with Cash vs. 1 year fixed mortgage?

[Luke Doyle]

I am currently listening to the BRRRR book by David Greene. I have listened to the advantages of buying a property with cash. In British Columbia though to buy a single family home in a market with a decent vacancy rate, you're going to need a lot more money than I have haha. I'm wondering if anyone sees an issue with combining two strategies. The "house hack" with the BRRRR.

What I envision is, buying a house with 5% down, getting a 1 year fixed rate mortgage, putting in a lot of sweat equity, rehab, move out, rent, refinance, repeat. 

Any glaring issues? 

Thanks!
