I rather not so I don't rock the boat with themThere are 4 people on the lease (including baby) and one of them is having loud parties and smoking pot.

I have placed some funds in contrarian type ETF's as insurance and have been thinking about some gold and silver.

Do you have a no smoking policy in the lease agreement  that you took over?

Some examples of habitability codes are functional toilets, functional sinks, functional smoke detectors and carbon monoxide alarms, weathertight windows and doors leading outside, bathrooms must have a mechanical vent or an easily opened window, a bedroom must have an easily opened window and either two electrical outlets or one electrical outlet and a light fixture and all pipes, plumbing and electrical must be per code.

The dude comes out 2 minutes later and word for word tells me "hey bro, **** that lady, it stinks like weed smoke in there and her two kids are in there."

Additionally, one of them is smoking on the property, another lease violation.

Or paint a wall, begin hording, add a electric space heater or start growing pot...not long.I tell my tenants it is for their benefit and safety for me to inspect furnace filters, smoke alarms, CO2 alarms etc.I personal am more concerned about my property investment than the minor feelings of tenants.
