so I have been buying up singles and convert them into duplex/legal suites in Durham (mainly Oshawa) and out west (mainly brantford). each project takes less than 250k and in theory after refinance I should only have about 120k left in the house. I assumed a 5% natural appreciation per year. with mortgage pay down and dramatic increase in rent right now it seems my return upon exit say in 5 years would be something equal to 30+% ROI annually. I know a lot of people do conversion but I haven't come across people who do it on a large scale and have many more data point to verify. I"m wondering if someone does this day in day out, what areas and pockets are the best for the balance of appreciation and cashflow, and how's the numbers really show. I have lots of friends who are interested but I don't want them to put their money into it just yet before I triple verify things even though I'm doing it...
