An analogous parallel to your question might be someone asking a doctor what guarantee they offer for a surgery vs having their neighbor do the surgery with Walgreens supplies and WebMD open in the browser.

Far too many ways to detail, but here are just a few:Fees: all kinds from what you may be charged on a checking account (a few dollars) to what IBs charge their corporate clients (tens of millions of dollars or more).Services: This includes everything from servicing your mortgage (large banks rarely, if ever hold these on their own books) to physical check processing to running the backbone of payment services that allows you to buy nearly anything anywhere with just a small piece of plastic you keep in your wallet.Money management: Whether for individual (i.e. very wealthy) clients or managed products like a mutual fund.And so, so many more ways.Will there be less income for the banks?

Ask them if they have a shotgun.Regarding the vapor barrier, I'd tell them you don't intend to do that but if they want to, you'll supply the 6 mil plastic (about $100)Otherwise, I would suggest that you tell them that if the property is not going to meet their needs, you'll refund their money when they give you back the keys and everybody goes a different direction.Based on what you've stated so far, I think these tenants are not ever going to be happy in this unit.

@Suzanne Player I’d be happy to share some information and tools with you to give you a kick start on CRE journey.The good news is that it’s not brain surgery and knowable with the right information.Send me a DM and I will send you a starter kit.

That's the best your can do as your current title company will be out of service for weeks anyway.Good luck.I rarely go to a closing. but did do one in Vegas at OS national it was a hedge fund buyer I was the seller.. and they had a pureal dispenser on the wall outside the conference room  Pens in plastic that were new ( I kept mine )  but I was the last in office signing they are all now home. 

It's even recommended that delivery boxes be left outside for two days, then picked-up with gloved hands, placed in a plastic trash bag, sealed, thrown away, followed by hand washing. 

I got in a bad motorcycle accident that had caused a spinal stroke after surgery which left me a paraplegic around 3 years ago which meant I couldn't lift heavy things and put them back down anymore.

He was given ONE disposable N95 respirator in a plastic box with holes in it and told to make it last for the duration.

You can use a plastic heater pan or even the bottom of a plastic 55 gallon barrel.
