Regulatory environment here matters, quite a bit. 

Dallas has a powerhouse economy beating national job growth by around 100bps, population growth is around 3 times the national average, it is a business friendly environment that attracts real talent, and it is a pretty affordable market relative to other similar locations in the nation. 

His job environment is not healthy, so he has been trying to find another job within the same field, just at a different establishment.

Not sure what is easier overall (cleaning versus buying and swapping) but I am fairly sure that cleanable is a little better for the environment and slightly cheaper (the filters are pretty cheap so we are probably on the order of $1 to $2 a month - negligible in the scheme of things).Good luck

My only concern is the rising rate environment and the impending economic slowdown many economists are expecting (granted they have been saying this for the past 12-18 months), and what impact this could have on getting overly levered.

I doubt they will extend it to the "A" lending portfolio as many of them have thriving "B" portfolios due to the extremely difficult lending environment the federal government has created in an attempt to help the affordable housing problem that was created by them in the first place. 

We have also built a relationship with members of the historical society, which has allowed us to operate in this challenging environment.

Also, this is going to sound rather controversial but I've been formulating this theory for a while but I don't think that the 1% rule applies to the Boston area and here is why:That is a rule of thumb to use in a cash flow environment.

You would be borrowing pre-tax funds and paying loan back with after-tax dollars at 5% that you could invest in tax-deferred environment and grow your wealth at 10%+ rate (there are many opportunities that would allow you to earn at least that such as private lending, syndication, note fund, etc).

That said there are always underlying factors that make markets or environments better than other times.
