I know its a little bit of a sticky time to be trying to raise rent, I just closed on my first residentelTriplex two units are vacant one unit has a tenant, D class tenant paying way under market rent. 

You can find a deal in every class and price point, but for buy and hold, you need to think about what type of tenants you want to deal with.

We found a 2-unit student rental property for $300k near a college in a B- class neighborhood.

Yes you can BRRR in this market but hard to find the good deals as everyone is going after similar asset class.

Easy to set up properties as classes /ovations, automate the invoicing (a nice looking invoice with my logo).

C-D class).

There are markets very prone to boom/bust cycles, as well as even asset classes within markets that are steady markets. 

If they are in a decent B class neighborhood I think you will still be able to rent them out in the near future. 

Could this be considered a B- neighborhood or is it more of a C class?

I'm based out of NE but the problem is that class C properties have been trading at sub 6.5% cap and north of $65,000/door which is insane.
