For instance, there is currently a nursing shortage across the US, and traveling nurses help to alleviate it.

Labor shortage??????

Is it possible to remove this exclusion (obviously by paying additional) like it is with a "shortages" exclusion?

But the NAHB also reiterated evidence of an ongoing labor shortage, saying, “The ongoing skilled labor shortage in the construction labor market and lingering inflation impacts account for the recent acceleration in wage growth.”For now, the hot market is still rolling.

Higher rates and tremendous demand for inventory by both owner occupants and investors have resulted in an inventory shortage all over the US - in Oregon and in Ohio.Hope this gives you some things to think about. 

@Ryan Duphorn  a  5 /2  and 1920 square feet IMHO isn't a good health care traveler accommodation unless you are in a area with a shortage of housing. 

Nobody in their right mind would sell at such because they simply don't have to, there is no shortage of buyers happy to out bid your desired landing. 

You won't have a shortage of recommendations when it comes to cashflow areas here on BiggerPockets.

The motivation is not necessarily to scale into larger opportunities but rather to achieve better balance and also optimize the performance of the projects and types of projects I currently pursue.I have no shortage of individuals who possess specific skill set who would want exclusive rights to that particular service vertical in return for contributing capital and a partnership interest (construction background and wants to take over all construction duties or someone who is a sales broker and wants to list all of the properties etc.)

The only “good news” is you’re paying for last year’s shortage and thsi year’s taxes, or this year’s shortage and next year’s escrow account.
