Let them know you are the new owner, how they can/should contact you for maintenance or other issues, tell them how they can pay, and set some basic boundaries (e.g. only call/text if it's an emergency).I recommend keeping them on month-to-month leases for 3-6 months while you get your footing and see how they are as tenants.

@Richard Quijano, Only if the president has declared a state of emergency. 

I panicked, called my plumber and said ITS AN EMERGENCY!!!

Hello all, I'm doing a flip in Palm Harbor and the plumber that I usually rely on has had a family emergency and will be out of town for a duration of time.

.+ Expand our partnerships with other emerging operators.

I wanted the doorbell in case they need to contact me in case of an emergency without a phone and/service.

It has to have ingress/egress to be safe - windows and doors that someone can get out of in an emergency - and of course operable plumbing, heating and air, and a way of blocking off access to your primary, but many people have done this; it's especially common in cold, urban areas where basements are full-size owing to deep footers necessary to build homes and space is at a premium.

YNAB is my personal fav, but whatev'z. ensure that your budget includes setting up a buffer (emergency) savings act for yourself.

your contract with them should require permission from you, unless it is an emergency, for repairs over a certain about. 

@Glenn Brook  - thanks for your service 1) locate and  hire a  proeprty manager ( PM ) to  mange the  rental  (  they will charge you a flat  percentage from the monthly rent)   2)  as a safety net - try to  locate a  friend / neighbor / realtive that is  close by that you  can leave a  key with  and   to ask for  emergency assistance  for any  unusal  issues that the PM  cant  assist with...this isnt crucial , but it doesnt hurt  3) make sure  that all parties   are able to  communicate with you  easily as  you are  stationed somewhere 4) depending  how profitable the  property is  and  how  easy / hard it  is to  facilitate - them make a  decision on  keep or selling it   and  also   a decision to  join  some of these groups  you mention
