I'm seeking advice on how to handle this somewhat touchy situation, as we have to live next-door and these folks who are fairly strange, and we have had some contentious interaction with them regarding their smoking in the property which is a violation of the lease.

I need to get the front house hardwired with smoke alarms ect. and was wondering if I would have an issue with the front studio?

In my novice opinion, this is what needs to be done to the house:Mold inspection/eradication (water damage from leaking water heater in attic)HVAC neglect (possible mold)10 Fogged Windows (house has numerous large beautiful windows that have become opaque due to moisture)Pressure wash exteriorReplace Carpets (approximately 1500-2000 sq ft)Paint interior walls/sand and paint trimPlumbing hardware has all been removed/needs to be replacedPool filled with excessive amounts of leaves/debris (pump is running)Excessive amounts of trash throughout house yard and pool houseLive Oak growing onto roof (arborist needed)New Sod (currently all weeds)Pool Deck ResurfacingGarage Door Openers have been removedLarge golf ball sized chip on bottom of granite on islandresurface built-insExterminatorPatch holes/cracks in walls (about 10 fist sized holes)Many light fixtures missing (10 or so in closets and bathrooms)smoke alarms missingSo, part of me was disgusted and felt very guilty watching my buddy conduct a walk through via the internet.  

There is nothing in our lease that forbids smoking cigarettes.

Make sure you have smoke/CO2 detectors on all levels and by all rooms and kitchen.

Not allow rentals for example, or come up with the pet policy or smoking policy or what ever someone things off. 2.

Rhonda Wilson what are you smoking?

A few of my friends are experienced investors and I was very involved in a smoke/fire rehab and sale of a SFR last year.  

Depending on what the layout of the building is, there is a good chance that smoke and water could have damaged much more than what is visible and sitting empty for that long can be difficult to for mold and pest reasons.If the damage only affected one or two units it may be easier to put at least a few of the lesser damaged ones into service quickly. 

I'm a full time investor now but I had careers as a respiratory therapist from 1972 to 1988 and as a software engineer from 1988 to 2014.Noteworthy accomplishments (in order of importance):Married my wife Brenda in 1981, Completed 2006 Iditarod sled dog race, first ascent Gilhooley Tower in Olympic Mountains in 1972, quit smoking in 1985.
