Some of them will become money pits.In midwestern cities that have experienced industrial decline, there is surplus housing stock. 

I would be concerned about the small, declining population.

Alas I've had to decline lending on their vast property holding no matter how long they wax lyrical regarding the size and worth of the properties owned.

So you can decline until they accommodate that. 

In fact, properties with the highest returns are most likely to be in declining areas since rents lag population migration and actual buying power.

Since we have started using PetScreening.com our number of applicants with ESAs has declined significantly.It really comes down to you want there to be units that are easier for the tenants with bogus ESA to rent. 

Let's say property values decline.

I've been using Mashvisor to look at properties all around New England and it leads me to believe that Cape Cod STR's have strong demand beyond the summer months.. only showing notable declines in January/February. 

It has declined over 50% from its population high and is still declining.

Alright I have a question I'm asking now becuase of the situation I am in.From what I understand investors are able to have 10 properties in their own personal name until banks start declining to continue to loan to that individual anymore.
