@Alex N. we pay $158/month so we are in a similar situations. Since its your first investment living in it will give you the opportunity to safely save and prepare for your next move. if you have tons of available cash I would go head and rent a cheap apartment and rent both your units out. But if you don't have allot saved up this is a good move.
For example. Lets say you rent out both units and you get an apartment, and for some reason you need evict the tenant and the water heater breaks. So at that point you need to pay all that plus your rent, if you don't have a good emergency fund you may find yourself in a bit of trouble.
I'm sure arguments can be made either way but at the end of the day its a manageable way to start investing. We look at it this way, we could be the average American Family struggling to pay our mortgage but instead we have a great starting investment and we only pay $158/month. Sorry if I rambled its 3:30am lol
