Quote from @Conte Cuttino: Property is in C+ area but in a different School district that’s B-If I sale I’ll get 30k profit after 9 months.If I keep as a Long term rental I’ll have to convert the garage into a illegal 1 bed cottage at an additional cost of $35k leaving a total of $107k left in this deal after 70% refi and closing cost.
