I recently hired a property manager to handle almost everything, like the rental license, lead inspection, and repairs.

Hire a new PM and evict them.

However when you think about the number of active people on the forums vs the number who are in that specific area and have hired property managers (meaning they're not self-managing) the pool gets a bit small. 

Some won't but I would want that so they aren't pulling random #'s out of the air.

Wynd detectors are usually good for air quality, their effectiveness specifically for detecting marijuana smoke can vary, as they aren’t designed solely for this purpose.

My recommendation is start owning real estate, putting a tenant in the property and hiring a property manager.

Do you manage it yourself or hire a PM? 

In fact, a good argument can be made to sell #s 3 and 2, pay off #1, keep some reserves, and hire a property manager. 

I think the expenses are light.If you want to achieve market rents, no central air is going to be an issue.

If you hire a handyman in the bay area you will probably pay $35-50/hr depending on skill level and the trade involved.This work was done in Richmond, CA.
