Check with a local contractor who has done many re-adaptive use projects.

Sides and shelves are 3/4" thick and the products can easily be adapted to most closet sizes to make it look semi-custom. 

I think most would agree that using an email address + bank is a reasonable expectation for pretty much any transaction in 2018, much less one with such a high value.I suggest that you should seriously consider either forcing the tenant to adapt to your online management (given that you aren't asking doing anything unreasonable with the rest of your tenants which I presume you aren't) or increase their rent as you see fit to pay for whatever inconveniences you're taking on to accommodate the tenant.You may have inherited the tenant in this "state", but unless some agreement was written into the lease prior, I personally wouldn't see that to be enough reason for you to go through so much trouble.With that being said, I believe 100% in going above and beyond for my tenants and if you feel that this is makes sense for maintaining the brand of your landlord business, I say go for it and good luck!

@John Blanton Investing strategies have to adapt to what is going on in the market.

Either sell or adapt to operating under the radar.

Understanding the verbage, like “house-hacking” and why it has picked up so much traction is just the tip of the iceberg when it comes to adapting and implementing change in the way someone should do business.

I’m not sure what your exact goals are, but you may want to consider adapting your strategy.

Once the early adapters have spread the current RE "virus" or strategy at too many meetups, and the trend has become a fashion for all, most don't realize, that it's too late to jump on that band wagon.

I installed the Automatic on-board diagnostics adapter in my car for personal use (I got it as a fun toy and decided I didn't really need it when the company came out with an upgraded version).

Pick a strategy and make it your own, grow with it, adapt it when needed.
