Starting Funds for new investor

[Anastasiia Greca]

I was wondering how much money do you need to start? I understand "The more money you have in your pocket - the better profit you ll get, the more options you ll have to chose from. But I still want to know what is the possible minimum to start.
Me and my husband want to do some house hacking. Specifically we are looking for duplex/3plex. Just the possibility to live for free is very appealing and make extra cash from renting the 3rd unit  (if it`s 3plex ) is very sweet. But unfortunately our funds are really poor. We are a young married couple, working two restaurant jobs and some more jobs on a side. Saving as much as possible. And also we have a very good credit score! So I think we can easy get a nice loan.  So I would like to know what is the minimum, on your opinion, we need to have in our pocket to start?
