Wow! Thanks @shri!
OP, I can confirm that you can have an agent handle the rent and duties of a landlord. My landlord is overseas and one of his/her relatives has acted as the landlord, collecting rent and to solve any issues regarding our rental. I don't know what's in it for her but this sort of relationship definitely benefits the landlord because it'd just be a mess if we tried to contact him about anything.
JVN, did you use any of the posted options in the end? I'm in the same boat....
Someone else referred me to an agent who is now handling my apartment. Too soon to say whether she's good bur I will PM you her contact details so you can reach out.
