I've lived here my whole life and have really seen a dramatic change in this amazing city. 

What if they build just outside the city limits, so they are not paying city taxes?     

The neighbor was the hottest in the twin cities and this house has 83 businesses cards of realtors who showed the property.

Verifying last 2 years of rental history and income extremely important to find the “best of the worst”.Make sure you understand the Class of properties you are looking at and the corresponding results to expect.The City of Detroit has 183 Neighborhoods we’ve analyzed.DM us if you’d like to discuss this logical approach in greater detail!

I wouldn't bother investing outside of the big city centers, nor buying anything younger than 30 years old. 

Let's assume that the neighborhood is a C class and the median income of the city is greater than 3X of the market rent.Here are some of the considerations I've come up with so far:- Units are in need of renovation and capex is too high or not available- Unit quality is not the same as market - Seller is worried about losing tenants due to increase- Vacancy rates are high or filling units have been difficult- Rent increase would take multiple increases over multiple lease periods to get to market rate if seller is trying to retain the same tenant- Seller inherited property and just want to liquidate- Seller needs to liquidate quickly (financial burden, sickness, quick exit from land-lording)It seems like I might be missing a warning sign about a deal if they are selling with current rents that are under market; but again, this seems to be most of the properties I've underwritten.And in the same vein, what should I be worried about when purchasing a deal with under market rent with the intention of raising them after purchase. 

There are lots of lemons in the various center city areas. 

I generally recommend if you're not going to buy a property in the city/market where you currently live, the next best place to look is where you have family (and presumably a place that you'll visit relatively often and easily).What is your price point and are you looking for turn-key properties or something along the lines of a "fixer upper", assuming you buy in Peoria or a similar priced Midwest market?

Looking to purchase a duplex, triplex or fourplex in Panama City and do short term rentals for summer months and long term through the winter. 

There are certainly value-added opportunities in the city.
