Are there exceptions for things like traveling nurses?

If you particularly want to live here, it's possible you may find some success doing something a little more mid-term, having a comfortable furnished place for business travelers in town for awhile to stay (I had a traveling nurse approach me once about renting my cabin for her 13-week stay, and there's many seasonal workers in town).  

@Thomas Yourkiewicz - There is a great deal of information on BP about Toledo to help you understand its national appeal vs other cities, price, cash flow, and ease of entry are a few.My biggest lesson learned in Real Estate in general is - whatever your niche, you will do just fine provided you specialize, create an offering that meets a need in the market, and stay the course when you have hurdles.This holds true if you specialize offering housing to professionals who need high-end temporary housing while assigned to long term projects...medical facility rentals with nursing staff provided...and for every aspect of servicing the investing community (hard money, note buying, appraisals, etc) which gets you out of the landlord role altogether.One sure way to fail is to constantly shift your focus and jump between cities, neighborhoods, or investments. 

There are many nurses that my wife works with who are also attending school online.

I was thinking of furnishing a unit or 2 and marketing to traveling nurses and other short term professionals but "worst part of town" would shoot that effort in the foot...brand new interiors or not. 

I will offer, think outside the box, don't just settle for your basic rental strategy, but consider maybe short term rental (Corporate living, Travel nursing, AirBnB etc).

Maybe even with the intention of putting it on AirBNB or specifically marketing to travel nurses.

But today say a lady post 1bed 1bath condo for $3000 month which to me is very fair...but the amount of hate she got was amazing.Not trying to kill your dream....but from what I see numbers are not as great as you might think.I've been on Furnished Finder for few years now, renting to traveling nurses.

The "off" season is here, though, so most are either repairing/switching to MTR/reducing their rates to meet snowbird/travel nurse requirements.

Echo what others have said — FurnishedFinders is an awesome platform for MTRs and travel nurses.
