granny in law suite cost in the midwest?

[Brad Pietrzak]

me and my sweetheart have enough for the down payment on a duplex. we want to save to install a granny in law suite in the attic. just a studio unless the numbers make sense for more of course. from what I researched it can run me 32k to 65k on the cheaper side if I can use unused space. our goal with it is to build the studio then live in the studio while househacking and renting the large units then when we save up for the next duplex do the same And just rent out the studio for 5 600 after wards turning the propertys into suido triplexes. any problems I may run Into trying to do this? How much do you estimate it would cost to build these to rental specifications?
