Its about $6K, that is if they didn't break the sewer line with the “feminine items” they were flushing that caused repeated blockages.I plan to sue them in small claims but there must be some way to track their new address.Is there a way to use “skip tracing” to find them?

So if there is in fact some way to invest reasonably in a high octane market without being some super cash-flush investor, then that'd be great.

However, if you are flush with assets, a plaintiff attorney may sue for gross negligence. 

I would also take this opportunity to remind them what does and does not get flushed down a toilet. 

For example, on one of our properties, we installed all brand new low flush toilets and reduced our water bill by 55%, a massive swing in usage. 

Well, people who are flush with cash or equity from the last 2+ years of crazy appreciation in real estate and the stock market. 4) Some investors are OK with buying low to negative cashflow for the first 12-18 months while they stabilize the property, increase rents, and fix deferred maintenance items.

Or after we went in and flushed the toilets in the vacant unit (per our contractor it's because the P-trap was dry from not being used in the vacant space). 

New circuit for the garage door opener, new LED lighting and circuits for the garage, Flush mounted LED lights (disable) for the the kitchen, New led lights for walkways, hallways, bathrooms etc.

This is the simplest method, but it also means your tenants are more likely to abuse the utilities by leaving windows open with the heat or A/C running, leaving lights on, ignoring the toilet that constantly flushes on its own, etc.3.

Another time they sent in a service call saying the toilet stunk when they flushed it.
