We get mostly families with kids that don’t want to disrupt their lives with moves.

While I'm not a fan of open houses, you may want to schedule one for a few hours to streamline the showing process and minimize disruption/intrusion for the tenants.  

Did you think how it might affect your tenants  Short term renters can be disruptive ,noisy and messy .Also the frequent  turn over makes it less desirable for long term tenants 

This will disrupt the rental business.

You may not want to disrupt that great rate, so you consider a heloc.

If rents arent considered on next apprsisal, it will completely disrupt my plan, which is cash out and buy bigger building....Anyone know why appraisor didnt ask for rent roll for this 8 unit?

I’ve considered it and interviewed options, but conclude that it would be disruptive and probably just more of the same — just different, with a backslide during the transition.

In addition, the house had a marijuana smell to it.I'm thinking it could be one of a few things:1) The tenants are concerned the owner is selling the house which means they might lose their tenancy and this was a way for them to disrupt the process to "keep them in the house"2) There was marijuana in the basement and they forgot the inspection was happening, and they didn't want to get caught with having contraband in the house as that would be means for eviction.3) There is actually somehow a flea infestation down in the basement (why the basement though when they have no dog and haven't reported it to the landlord?)

She has a reputation here for taking a long time to do projects and being very disruptive to neighbors.

That could have potentially disrupted my vigorous napping schedule so was a no go for me.
