Is it possible to buy more than 1 property under 1 mortgage

[Jessica Sheppard]

I know these questions may sound stupid to the experienced, but I am just trying to get some different ideas and see what other investors have done in the past when first starting out.

I am in the process of getting a pre-approval for a conventional loan with 5% down.  

If I am approved for 150k mortgage and I find 2 or 3 homes that I want to purchase that are under or equal 150k is that possible? What are my options?

If I am going to use one as an owner occupant can I do 203k loan? Should I get a 203k loan for the owner occupant and conventional for the others? Can you do that?

I would love the idea of house-hacking a duplex or triplex, but there is not a lot in my farm area available comparable to my family size that make sense.  

Any advice, comments, or suggestions would really help.

Thanks in advance.
