Like to get a pre approval and secure the deal.

I've learned a lot about buying / renting out a duplex and hopefully one day owning a large rental properties, so I know this is how I want to invest my money to ensure that a passive income stream is coming back to my family from real estate but I don't actually know how to make my first duplex purchase.

I would recommend educating yourself on underwriting multifamily properties so that you can ensure that you get a good entry price and I would also encourage you to plan the renovation business plan carefully as this is the area that carries the most risk. 

I have already secured a FT job that I will be starting in June, and I will be graduating in May.

Most are set up to help you virtually and will use secure document transfer and electronic communication via email, Skyle, etc to communicate with you.

How can we accurately perform a market analysis to ensure we are investing in the correct locations?

Make sure you also get any security deposits and last months rent per leases that you should be reviewing.

Will it be difficult to secure 3.5% down financing on the second home since I will have gotten a mortgage loan a year prior? 

The receptacle in the 2nd floor hall bathroom is loose and needs to be properly secured to the junction box.
