Either Rent or Own... but Rent to Own in my experience has never worked out well. In fact, almost all of them that I am personally aware of turned into the buyer filing a lawsuit against the seller.
As an agent, I stay as far away from them as I can get!
Owner financing may be an option... but to be honest... with how easy it is to get a first time homebuyer loan, it makes no sense at all to go that direction. It's easier to get a new loan, and pick out a home you really like.
When it comes to any safety/crime related issues, it's always best to contact the local police department with all your questions, hear all there is to hear firsthand. If unfamiliar with the area(s) do revisit more than once and at different times of day, possibly chat with locals/neighbors. Real estate professionals are prohibited from steering, enticing a buyer to purchase, or not, in specific neighborhoods.
