Quote from @Kaleb Dodson: @Jerryll Noorden If your tactic is a website, then you by default are using "gadgets, a strategy, etc" to bring leads in, and though you aren't technically generating leads, you're still using tech and gadgets.

I see discussion about smoking and no-smoking in rentals.What experiences/issues have you encountered due to vaping in your properties?

As are cellular towers, fiber, the internet, the local gas station, vape shop, computer monitors, keyboards, search engines, and just about everything else you can imagine.

She thinks it’s ok to stay for free and she deserves free housing, non paying her dues or any thing just because she does not have a job (on purpose) and does not have money ( has all money for fancy furniture and gadgets)But anyways she has not paid her move in deposit ( paid partial) and has not carried renters insurance.

But there are always oddities like I bam smoking, vaping and e cigarettes.
