If it is not urine, smoke or mildew it would seem fresh paint and clean carpet would take care of it, i have used clenaire blocks of odor absorber $20 at Ferguson in the return air vent (have you cleaned there?

I don’t mind keeping the tenants but I know the lease agreement may be to relaxed in areas such as smoking in home which is a No No for me and my properties so certain things I want to change but I have no problems at this time with keeping the current tenants other then smoking and certain things like pet requirements.

That has a negative effect on supply of affordable housing, and it immediately pushed rents up in saint paul; despite what that was meant to do in the first place.  

Those fittings work on practically every type of modern supply pipe, except galvanized, which requires a threaded transition. 

You must tear out any damage, you must treat every inch to get rid of smoke smell, and finally piping or wiring may not have burned, but it may have melted and need to be replaced. 

I have a checklist I walk down each visit to look at plumbing, locks, smoke detectors, windows, pests/mold, overall condition, pets, etc.Scheduling them is the biggest pain.  

I did a quick search and found that the Multifamily properties here in the South Bay are really scarce in supply.

Yes, the effects will be major and global (beyond what we are seeing with supply shortages as a result of COVID) but we haven't seen one yet...

Choose one contractor and go with it-Don't paint smoke rooms - Rip out smokey sheetrock instead of trying to paint them ... repeatedly -Buy a home warranty - we had an AC on the way out....and i didnt buy one- it died 2 days before keys were handed over; it cost me $8K Did you work with any real estate professionals (agents, lenders, etc.) that you'd recommend to others?
