Newish to this Site. Looking for Advice!

[Alex Webb]

Alright, hi everyone! I'm semi-new to this site, and looking for some advice. 

So a little background about me, I am 21 years old and live on the eastern side of Mid Michigan. I work as a first responder making about $28,000 a year before taxes and with no overtime. I live with my mom and I'm looking to start investing. My father is a real estate agent and he has told me about a first responder mortgage that I would qualify for with a very good interest rate. My understanding is that it is not an FHA loan because it is through a bank and therefore I am not required to live there. I'm wanting to get a multiplex for my first property. The good thing is that houses in the area I'm looking are cheap, unfortunately so are the rent prices. Maybe I'm just overthinking things, but I'm wondering how/where to start.

Some numbers for comparison:

According to my father who is a real estate agent, a typical multiplex unit (depending on size and area) will go for $350-600 a month. I have found a 4 unit for $65,000, rented at 100% occupancy. If I estimate on the low side, I'm thinking $425ish a month per unit bringing the monthly total to $1700 a month minus about $400-500 for a mortgage.

Or

Option 2, is a 2 unit listed for $47,900, but has been on the market for 3 months. One side is occupied and the other is not. The side that is occupied has been occupied for 10 years by the same renter, and their rent is $400 a month with the other side being $400 a month.Mortgage would be about $300 a month with landlord covering water expenses,

I'm wondering if what I'm looking at is a good place to start. I'm wondering if now is a good time, or if it's too soon, or if I don't make enough, etc. Need some advice from experienced people!
