@Cal EwingIf you are trying to grow the U.S.A. side of your business, you will most probably want to retain earnings in-country and not be forced to repatriate them back to Canada - the currency exchange back and forth would only line the pockets of the FX folks and the additional taxable events will only make the IRS and CRA happy.To do this requires some form of entity in the U.S.A. and will necessitate filing taxes there.  

Tenants move as necessitated by life and have no regard for a lease.

So then, am I correct to assume the difference in terms of what necessitates mandatory disclosure between the investor who negotiates/purchases the short sale from the lender with the intent of simultaneously reselling it (simo flipping) vs. the investor who negotiates/purchases the short sale from the lender that plans to resell it at a later time is that the investor who does a simo flip knowingly negotiates the buy solely contingent on having an end buyer secured well before the close that has agreed to purchase the property at a profit above the price the investor originally paid and therefore MUST disclose all details of the transaction to all parties involved?

Summary ejectment procedures must now be handled in district court rather than magistrate court necessitating hiring an attorney to evict a lease option tenant for breach.

Bathroom will have corner entry shower insert, and a sizeable single sink vanity.2 zone mini splits will handle HVACElectrical will need to be redone 100amp wont cover both and due to the EV charger in garage, electrician says it will be pushing it with split 200 amp panels, possibly necessitating a split 400 amp service.

My take: Something is going to break if the Fed keeps rates that high for that long, necessitating Fed rate cuts.

Of course if there are different LP partners that will necessitate separate entities, even if the underlying assets themselves don't justify the need.

A heavily promoted transaction with a smart seller necessitates rigorous examination and documentation.To ensure accurate assessments, I advocate hiring third-party professionals in financial research and due diligence.

The trouble with many BRRRR-candidate properties is they may not qualify for conventional, FHA, or VA financing, necessitating cash or hard money for the initial purchase, and then a refinance (the second R) after renovations are complete. 

Not all locales necessitate business licenses especially for real estate investments.
