Take pictures and measure your risk/reward.

Matterport, in my opinion, is a step above traditional video tours because it allows people to tour the property and view the measurements of each room. 

When I first started this thread, I really was hyper focused on passivity, but I have tried to implement more immediate and less drastic measures to help reduce the stress, so I can hang with my current primary asset and squeeze a good amount of appreciation, that is still available.Thanks for contributing and best of luck!

Even if I'm not ready for new flooring yet, if I know I'll need flooring soon, I'll lock in the price on a holiday and schedule getting the measures a month+ out when I'm ready.  

There is too punitive measures and shorter time horizon for that loan to mature and eat away at your equity buffer.

What we need though is a standardized way to measure the metrics.

@Reesey Ann - To this point, you might want to invest in some security measures to ensure this does not happen again.

Having said that, there is no problem having SMART compassion and taking safety measures (15 months rent in an escrow account). 

The homeowner measured  WRONG .   

A few things you could consider:House Rules: Make sure you have clear, firm house rules for your STR guests regarding noise levels, shared spaces, and respecting the privacy of your LTR tenants.Noise-cancelling measures: You could invest in things like soundproofing the walls or adding landscaping (like thick bushes) along the privacy fence to further dampen any noise between units.Separate Access: If possible, ensure that the STR and LTR tenants have separate entrances or parking areas.
