Our tenants were great about it and they took a short vacation to a nearby hotel and we had the house tented and fumigated in 3 days flat.In your case since its a duplex you need to get both units done, otherwise whats the point? 

Would you buy a commercial property within Trenton today or would you instead look at nearby towns/other areas in the South Jersey area?

Check out the nearby members and network at https://www.biggerpockets.com/meet, it will help you a lot to find partners that can help you out in investing.

If there is a clear value add to be done, and its being proven with a substantial number of units, or nearby properties are doing the same thing, then I'm fine with that.  

Call nearby MHPs and ask them about lot rents, vacancies, etc.  

Call nearby MH Parks.  

Would love to hear more about what you are finding in The Woodlands and nearby area.

I'd look at properties that would work well for "entire space" listings - close to sites and attractions, safe area, bars/restaurants nearby, etc.I expect once our AirBNB listing becomes more seasoned, we'll be clearing our mortgage by well over $1,000/mth - providing more cash to fund future real estate deals.

I will stick to the traditional investments nearby where I can see and touch them. 

I was told my uncle would collect it for him, because he lived nearby.
