I am primarily hosting traveling medical personnel because there is a lot of demand for these professionals in our area and because my units are suited to their needs.

As a resident (who travels a lot) I would say the Midwest does not have the attractions like palm trees & beaches (the great lakes are cold) or amazing mountain ranges, which often come with some disadvantages like high cost of living or hut/humid weather, stroms etc. 

Beachfront or properties near attractions tend to perform best.Mid-Term Rentals (MTRs): These are gaining traction, especially with traveling nurses and remote workers.

Living in a great travel destination like Sonoma you should consider a duplex or triplex and operate the other unit(s) on AirBNB, VRBO, etc.

EPA violations typically travel with ownership.   

I'm doing quite a bit myself but the cast iron part is a job bigger than I can handle.Any recommendaitons for rough-in plumbers in NJ and willing to travel about 15 miles outside of Newark?

I (barely) watched some of the podcasts cause BP shows up on my youtube feed when I travel. 

Examples might include areas in the Midwest, Southeast, or Sunbelt regions.Multifamily Properties: Consider duplexes, triplexes, or small apartment buildings to increase unit count and spread risk across multiple tenants.Short-Term Rentals: If you’re comfortable with the management requirements, STRs in vacation or business travel markets can offer significantly higher cash flow potential than traditional rentals.Value-Add Properties: Look for opportunities to buy undervalued properties where you can force appreciation through renovations or better management.Decision FrameworkRun the Numbers: Compare the projected cash flow, equity growth, and tax implications of selling versus holding with a refinance or HELOC.

Also, I'd add that any second position debt, preferred equity, or their brother's, sister's or cousins in any shape or form are at #2 on this list, in really any asset class. 

If you're intentional with it, you may be able to include some travel deductions as well.
