I am not attending grad school yet, but I am working and saving cash. One investment I was considering is a Duplex. Ideally, I'd live in one half and rent out the other and make a few hundred extra a month (I've read at least $200 is a reasonable expectation). I am going to be applying to graduate programs full time this coming fall, maybe this idea is a little weird, but would owning a duplex in the area, while simultaneously renting it out be viable while in a graduate program? My first order estimate for rent would be around $1000/month for half the duplex, but with mortgage payments Id estimate maybe $200 would go into my pocket. Has anyone tried something like this? I see it as an opportunity to ave some place semi-permante while supplementing income. If I decided to move, I would just keep the duplex and rent the other half out. There is the risk of having no or bad renters though.Thoughts?
