My only concern is what if they close shop or sell their business?

Account Closed Contractors are businesses .

This only fits with a small office type business. 

Hi all, my business partner and I have recently filed for our LLC to start our real estate investment journey in Ohio.

You can still pick a business name out of thin air and tell your tenants this is the name of the company that manages the properties. 

In the meantime, think "time value of money", you get the use of that money to leverage into another property, do needed renovations on an existing property, pay for your kids college tuition, or keep your business afloat until this pandemic goes away and you can take a needed vacation.

Being a wholeslaer is having a business.You are in the business of finding and buying land/contracts for a short duration and then immediately selling them.One typical expense for a wholesaler is all the advertising costs to find motivated sellers.

I'm in Tampa, FL but focus on fix and flips in the Fort Myers-Naples area with my business partner since 2021. 

For example, a quiet neighborhood that used to be a busy factory area might have hidden issues, like pollution.

Myself, significant other, and my close friend/business partner have been renovating his personal residence for the past few months with the intention of renting it soon.
