Ask your lender if they have a "work around"For the inspection,  a pressure test can be done with an air compressor to isolate the problem.  

Sometimes we will spend hours trying to find a leak, turn up nothing then have to disconnect the indoor and outdoor sections to pressurize each individually in an attempt to isolate the problem.

But one thing that we know for sure: if you expect to receive the liability protection that is promised, you absolutely must isolate all of the activities of that specific property in that specific Series.If a tenant sues Series A, and he has signed a lease with another entity, then the Judge will probably allow discovery regarding the other entities to find out whether you are really operating this investment inside this Series, or you are spreading it all over.After all, in Texas we are still litigating the definition of "doing business."  

Just to clarify @Mike Fletcher, the importance of the formation of the Michigan LLC to isolate your assets is not particular to the fact that it was formed in Michigan correct?

This provides isolation to protect your personal estate / possessions and is your first layer of protection.The S-Corp is your operating company.

Adam, you cannot be lenient, it does not matter if you have 21 or 2100 units, you have to have firm rules and a system that is consistent, send a strong message and is willing to move forward with the next steps if need be, in the same respect if the tenants have been in the units for a long time and now have started slipping you have to ask yourself, if something happened to them and if this is an isolated incident or has this become or always has been a chronic issue.

Although there was an extended lockdown period, I believe the decisiveness to reopen small businesses such as restaurants ahead of other states substantially helped isolate and limit the economic hardship to tenants and landlords.In a sense, it provided the perception of a light at the end of the tunnel and helped landlords work with tenants on rent payment plans.

If its cost effective for you, many investors just have one flip per one LLC so they truly get isolate and discard the liability. 

@Kieren Gromowski my big concern would be that Manhattan is a small market that is geographically isolated from any other metropolitan market.

@Joe GeistYou don't really "borrow from the cash flow" in an isolated fashion.
