The lease has a statement that says "If this property changes Ownership due to sale, foreclosure or deed back to the lender then this lease may be terminated with a 30 day notice unless the new Owner agrees to continue the lease and both parties wish to do so".

It is easier to show it to everyone and encourage everyone to apply to not be accused of leading or discriminating.You can also set up appointments open house style where you are there only a certain time and they overlap, because you will run into no-shows.We show all interested folks the place and offer an application. 

Should I continue saving and buy a property up here where I would be able to manage it or should I buy in south Florida and hire a property manager?

As a new landlord, what tips would you provide to me to make sure I continue to be profitable and grow?   

Always looking to meet others in the area that are developing, as I am new to the game but hope to continue to do more....Thanks all for your thoughts! 

You did not indicate if you plan to continue to live in CA.
