I have tried to remove National Parks from mine and a call did not do anything.  

We removed it, and when with 2 propane heaters (one for the basement and one for the cabin).Some other things to think about:- Hammock- Bug spray- Boot tray for shoes- Snow shovels- Coffee and condiments for when they are snowed in and can't get out- Fly swatter for summer- If no internet service, then consider getting Starlink. 

Removed a pool it will cost a lot of money also. 

Rehabbing units, removing problematic tenants, new infrastructure.

9) adding multiple ADUs or adding an ADU to a quad looses F/F conventional financing.

Removing tenants is a serious pain in New Jersey - though I realize those specific deals may be rehab and profit opportunities.

If you ask the manager to justify a fee and he starts hemming and hawing, move on or require them to remove the fee.

Heck I had a lot of posts removed because they were on the line of promotion.  

After removing the mold risk and opening the walls we found moisture coming through the foundation showing improper foundation work done over time, including wood foundation being used in the rear.

I would have assumed we would start the eviction process on the 5th after they missed rent for a second month, so we have the option to remove them as fast as possible if they continue to not pay.
