@Sofia De Santos Tavarez if you haven't already, have the property professionally inspected.This should catch MOST of the structural, health & code issues - but not all.

It could certainly be a concern - but depends on a lot of factors - are you looking multi or SFR? 

The best banks that I have found based on your main concerns are smaller, regional, community sized banks.

Extremely communicative and Bob spent time over multiple phone calls answering specific questions I had concerning the deal.

The problem (as you have cited) is trying to understand what you need (you don't know what you don't know), where to get it, qualifying its source(s), and the validity and usefulness of all that.Pardon me if I've gone into this too much, but I meet many people with the same concerns that you are voicing and this is offered, as much as possible in direct response to your post.Please feel free to contact me if you have any comments or questions. 

Property values have been appreciating rapidly in recent years, and the city’s population has started growing again—a trend we haven’t seen in decades.I’m also based in California and have been investing in Detroit for several years, so I understand the concerns of out-of-state investing.

The concern with places like Irvington will be once you move out and no longer owner occupy how do you raise rents legally.   

Unit 3 - mid-term rental (this would be best for the most private unit as most mid-term renters are more concerned with privacy and creature comforts than amenities)4.

Then tell us the nature of your remaining questions and concerns as to each remaining aspect, so people can have intelligent, focused, SHORT, conversations with you on each issue you present. 

I would recommend saving a little more.From what I've read about Cleveland is that you need to be concerned with high crime.
