There's also potentially some liability protections you can have in place by having the work done by the GC rather than you as individuals (discussion for your legal team). 

Portfolio loans tend to have increased fees and interest rates along with a partial release clause that could potentially restrict you from selling one of the properties included in the package. 

A and B will typically have more potential for appreciation and solid renters. 

Potentially, it also depends on the debt you carry. 

Today I am going to give a few tips about assessing the location of a potential property that you are looking to buy and a few things I like to look at!

Definitely potential in the area.

You will likely meet some real estate agents that would be more than happy to sign you up as a client for a somewhat extended search (to be your agent when you are ready, to get you signed up, send you potential opportunities, etc.)

I know based on the Illinois Condo Act, HOA should cover the wall, insulation and electrical. 

No one here is saying this doesn't have significant potential upside, but they are making you very aware of the significant downside.

In that case, you have to break down the rents vs. liabilities, show that the mechanicals, roof and everything is in good shape or have reasonable repair costs laid out, you need to know the appreciation potential, and the comps.
