In CA you can rent ADUs but can only rent JADUs as a separate unit if the owner lives on the property.  

[2]   Do you know if the buyer is going to owner occupy or is it an intended rental?

Plus you can be more selective of the tenants you rent to being an owner occupant!

if i were to acquire these and have them be owner financed, I would want clear title and the other mortgage on this lot removed - especially if my loan has a balloon on it that matures prior to the existing loan, as how would to provide clear title?

Some of the owners had wanted to sell and others didn’t.

Good pro tip is to not tell the tenants you're moving into next door that you're the owner but just affiliated with the property manager.

As the owner of a property management company in Washington, I have encountered this situation before.

But I do have some family in Canada that have told me there has been some tax increases to the STR owners to try combat housing issues.

Letting go isn’t about being careless—it’s about being a strategic business owner.

In Indianapolis C to B class neighborhoods I have rarely seen insulation upgraded on rentals especially doubles that have never been owner-occupied.  4th air gaps,  poorly fitting windows, and doors can be easily corrected with proper caulk and weatherstripping (usually).
