decided to buy one property from a friend

So it is private sale. Continue with my student rental journey:
200 meter from university hospital. Land 70x140. about 50 year old Ranch with finished basement separate entrance. 5 bedrooms ground floor; 3 basement unit. Fully rent at $3480/month ( About $600 utility cost/month). Private sale to me $325,000. Cash flow about $1580/month at 5 year fix rate 4%, $1300/month at 10 year 5.25% fix rate (Canada does not have 30year fix). With 20% downpayment. My friend had spent about $55,000 to do all the work last 3 years.
Right now in process of convincing wife to help me pay downpayment.
