Understanding the 50% rule

[Jabari Marshall]

Hi All, Would someone explain to me how the numbers would fit in to the 50% rule. To my understanding half of your total rent will go towards your expenses. So correct me if i'm wrong but half of my rent should pay for my.............mortgage? I'm looking at duplexes now and i'm trying to figure out which ones will meet the 50% rule but i'm not sure what numbers to plug in. I will try to give you some numbers, hopefully this will work. 1st duplex: aking 165k 2bdrm/each unit rents 775 per unit taxes 2500/yr 2car garage 2nd duplex:asking 139k 1bdrmm/each unit rents for 600/month taxes last year/1780 no garage
