When I first began real estate investment more than 40 years ago, it was a much more accommodating industry.

The tenant should have no problem accommodating this and will probably be very happy that you are taking such good care of your property. 

We get 13 million visitors a year (and that number continues to climb), so 1000's of cabins are NEEDED to accommodate all those tourists.

Using the exchange proceeds in your account your Intermediary purchases your new property (in theory less expensive than what you sold) and holds it in an entity called the Exchange Accommodating Title Holder (EAT) apart from you. 

I do however have to have kitchens and living  rooms that can accommodate families.

Generally speaking, you would need to accommodate a Disability Service Animal, but not an ESA animal unless it was psychiatric related. https://www.nolo.com/legal-encyclopedia/texas-laws...  

Ask them what they want out of the deal and see if you can accommodate them.

We are thinking about putting a house on the market in DFW (updated starter homes are going in hours under multiple offers) and I am pretty sure financing bank's appraisal is going to come in at less than what a buyer is willing to pay for it.We're not going to lower the price to accommodate bank financing when it's such a hot seller's market (unless we have to, and I don't think we do), so do you think I need to communicate that in the listing, or just let agents know?

If the sales person you are working with can't accommodate you then move on. 

To accommodate this oddity the IRS allows that a capital lease of greater than 30 years remaining duration is the the same as actual ownership of the property.
