In Greece, the average  time is 15 yrs. but some banks have 20, 25, and 30 yr. mortgages. 

Otherwise, talk to the neighbours. 

If they then want to go after your neighbour for costs, that is up to the tenant. 

I’m not a realtor, but this is what I hear from the sellers and the neighbours.

Talk to the neighbours.

My first strategy in Orba is buying old midsize townhouses with patio from the bank at a very low price so I can sell them quickly for a very reasonable price to investors/neighbours who want to rehab them.

If not, find a new PM.If the neighbour says the place is a mess, why not ask him to a take a photo and send it to you?

At the time, Greece was a cash society.

This will promote both cracking and the plaster pulling away from the lath.While a to-the-studs gut is the ultimate remedy, it is a filthy, filthy job - obviously the unit will need to be vacant and tenants in neighbouring units will still experience some dust.One other point, if the property is towards the end of the lath-n-plaster era (or the blue board and plaster era) ... ie. the 1930s - 1940s, you may want to have the plaster tested for asbestos content before undertaking a renovation.

If your tenants have a problem with the neighbour they should be calling the police, not involving you.
