In my personal experiences a lot of structural items start with bad drainage.

I personally would not invest in detroit as historically its not a appreciating market and for cash flow and I invest primarily for appreciation - I go off the location location location mantra. 

The challenge was balancing the relationship between landlord/tenant and a personal/friendly relationship.

Who is personally going to be liable if the guarantees aren't met?

Consider whether an LLC is right for you—it can provide liability protection but isn’t essential for a single property, as personal liability insurance and an umbrella policy may suffice.

Are you able to go there in person to build your network? 

They seem to be a reputable company, but nothing beats personal testimonies!

So they price those homes at what a willing homeowner will pay for their personal residence.
