BUT toilets are cleaned everyday and the crime scene would not be much worse than that.HIV would not be the major concern because it is not stable on surfaces.  

There are a couple risks that make me weary and would love to hear if anyone had some stances on the subject that could help me validate/eliminate my concerns.

In my humble opinion as far as SFR's are concerned not much.

Minutes from bus routes that connects to the train which connects to major parts of the city.Ideal Location - located in a mature neighborhood surrounded by several desirable schools.Near local amenities such as a shopping malls and leisure centers.Home setup is desirable - top level and potential legal basement for dual incomeHome is in rough shape and can add value to it (BRRRR method) which is what I want.Alley and Garage parking.Cons - Located on two main roadsThere is street parking in front of the home (2 lanes of traffic both ways). 

Mostly can’t be cured with rehab and exit will be a concern.

My real questions/concerns lie here....

Should I be concerned about the turnover 3 times in 3 years.

My recommendation:  Focus on Single Family Homes and look towards the BRRRR method. 

SFR's will nearly always be easier to sell and will also almost always appreciate better than a duplex, but if replacing your income is your primary concern I would strongly recommend you consider House Hacking a duplex.3.

So then there're different methods to do the actual gifting?
