I would use an experienced broker who can shop around and help you compare best terms on a National basis.

Also, not very easy to use typical methods of valuation like comparable sales - there is no public tax assessor's website that you can just freely grab this from. 

The population is officially growing again, and there’s been a lot of investment in infrastructure and development in recent years, which makes it unique compared to some other Midwest markets.One thing to keep in mind, though, is that Detroit is very much a block-by-block city.

The rent-to-price ratios are strong, property values remain relatively affordable compared to many other cities, and the city has been seeing real economic and population growth.I invest in Detroit myself and have built a portfolio of 12 doors there.

That would show you exactly what they are each looking at to compare your property

A unit within walking distance of the Blue Line in Wicker Park might rent for $2,200/month compared to $1,700 further away.10.

It also helps to show them the amount of interest they can get when they add up 30 years of payments (compared to the sales price). 

Comparing just those two things, you would save way more money in the long run by avoiding the annual mortgage interest.
