Do I want to tie it up in an illiquid investment where I have to fight with tenants, replace HVACs, and vacancies hoping to hold on long enough to make money in 10 years of appreciation or would I rather keep it working and liquid until I can make a better investment when the time is right? 

No need to fight any holy wars.

Is that worth fighting over?

what if tenant fight each other in the house or have room break in and sue the landlord?

Just be careful STR are allowed in your town, many towns are fighting them ie.

Also, whether they have a ten year lease, a month to month lease, or its undetermined, you can't do anything for a minimum of 90 days (That pesky federal rule again...).

Sometimes the battle you choose to fight might be inconsequential, but it might blow a deal up.

In court, the tenant is merely fighting to recover the amount of the security deposit. 

I likewise have no dog in this fight as I don't really care for wholesaling. 

Hands down it's Detroit.Folks will fight me on half of that, saying it's just a cash flow market.But they are 100% wrong.Detroit is uniquely positioned today to offer both cash flow and outsized appreciation.
