First, decommission or put a bullet=proof lock on attic access. 

This boat is a decommissioned 81-ft tug boat known as Miss Laura with sleeping quarters and a kitchen.

I recently decommissioned this old steam boiler and dropped 2 hot air furnaces in the attic for the 2 2nd floor apts, and put 2 small hot water boilers in basement for the 2 first fl apts.

It's a 4 plex of mostly one-bedrooms for $120 - but there is a 5th unit that has been "decommissioned" - (not sure why) which could mean it might get close and I'm sure the bank would take $100k for it, maybe less.

You can't live in it without water (although showering at the Y is a possibility) so decommission of the bathroom is a problem.

Mike those rates sound high but if your property is in California I am sure repair man costs will be much more than here in Georgia.If you learn anything with tenants with you have to " tenant proof" your units.That means take out gas stoves, if your older unit has a fireplace decommission that so it can't be used, garbage disposal you take it out.Do not give a tenant a chance to screw something up and break it.

Boilers needed to be decommissioned and gutted.

We hired a contractor to decommission the septic system and tie into the town sewer in order to sell our house.

For example I've bought in Rosamond, CA and Dayton, OH, because the odds the AF will close down their major test base and their major acquisition hub are close to nil, but I'm really weighing my decision at the next base I'm slotted to go to, in Albuquerque, because that bases primary roles are directed energy (which is slowly being decommissioned), special operations, and the nuclear mission, of which neither of the latter two "Have" to be in ABQ, in fact, Spec Ops can easily move to Florida, and Nuclear could easily move to a number of other places.

From experience I had a triplex that was not allowed due to zoning and we had to decommission one of the units.
