Sell or keep

[Beau Alesi]

Hello. Me and my wife own a house which is almost like a 2 family although not officially a 2 family . It has an accessory apt permit. We rent the upstairs and the accessory apt and get $3,600 between both . Our mortgage is about $280k balance and roughly $2,900 with taxes and insurance .The current family that lives there offered us $550k and that’s about what it’s worth. We are trying to decided if it’s worth it to keep the house being that we walk away with about $700 profit as we don’t pay and of the utilities . There is a maintenance factor that needs to be considered . I do understand that . I thought I came across something once ,like a calculation that determined whether a house was worth keeping as a rental. Any thoughts ? Thank you very much .
