Was interested in the conversation.

It’s always a good idea to document the conversation too, even if it’s just jotting down the details for your records.If they don’t take the warning seriously, you’ve got options.

In my experience apt. conversions from single family are more prone to noise transmission. 

There were lease violations disrespecting the other neighbor's leased space and harassing the other neighbor and they smoked in the property against lease, lied about conversations, has made up stories about plumbing issues that plumbers couldn't find causes to, tried to get a dehumidifier and force me to pay, accused me on two different occasions very agressively in regards to the heat/electric service.

Adding Value to Your WarehouseTenant Quality & Lease Structure: If your current lease is below market or lacks favorable terms (like annual rent bumps, triple-net structure, or long-term commitments), renegotiating could boost value.Energy Efficiency Upgrades: LED lighting, insulation, and solar panels can make the property more appealing and cut operational costs.Loading & Access Improvements: If feasible, adding dock doors, better truck access, or high-clearance storage can make your space more attractive.Flex Space Conversion: Depending on demand, creating a small office buildout within the warehouse can appeal to tenants needing mixed-use space.Diversification ConsiderationWith 70% of your income tied to this one property, diversification could make sense, but if it’s truly hands-off and cash flowing well, you may not need to rush a sale.

Learn the area, meet other investors at meet-ups and one-on-one conversations, and once you feel more confident, you can make a purchase to live in. 

Quote from @Havital Miltz: Wow a bit of a sticky situation, did you have a conversation with the seller, directly or thru your realtor prior to the closing to find out if the tenant knows they are supposed to move out?

Some of the best advice I got that I will forget was this:"SOME OF THE BEST DEALS, ARE THE ONES YOU DON'T GET"Let that sink in for a while...I remember 4117 s Michigan Ave. here in Chicago, it was an awesome 8 unit full gut condo conversation - I loved the deal and still belileve it would have been a great deal, but would have pinched me so thin I am not sure how I would have survived. 

I HIGHLY recommend you have a conversation with an attorney. 

Cash for keys is probably not effective since they don't have anywhere to go [most LL are not likely to rent to them] however, I plan to have that conversation and offer any assistance with moving.Thanks again
