If you stay in Northern Minnesota you could look to locate closer to Duluth which has a large supply of duplexes at prices much below $500K.

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. 

If you love property management and want to start a business keep looking into it.Otherwise keep buying income producing properties to generate wealth.

@Joe Gellenbeck Recommend you first figure out the property Class you want to invest in, THEN figure out the corresponding location to invest in.Property Class will typically dictate the Class of tenant you get, which greatly IMPACTS rental income stability and property maintenance/damage by tenants.If you apply Class A assumptions to a Class B or C purchase, your expectations won’t be met and it may be a financial disaster.If you buy/renovate a Class A property in Class D area, what quality of tenant will you get?

We walked through a property that we went into thinking we were not going to like it and we ended up loving it and jumping on it pretty quickly after because the seller was getting other cash offers and the price/location/set-up of the property just fit our situation well. 

They can also help you analyze the highest and best use for the property and location.

Out of the 300 properties I manage, we only had 1 eviction last year.

Long term $ can range from 6's-10% range depending on all types of factors - LTV, location, unit count, debt coverage, borrower strength, full doc or lite doc programs, etc..

With no mention of price, location, rent etc.....
