Honestly, upgrading to a commercial-grade stackable setup like Speed Queen or Maytag might be your best bet.

Is this just someone betting big on inflation?  

I bet the rate of Engineers going homeless is all but 0. 

If your goal is cash flow, then your best bet may be to live in it for 2 years, and then take that tax free gain (250k single person, 500k married) and buy elsewhere. 

Other companies people use are SNSC, FCI, Landhome, Homekey and others.That would be your best bet.

Your best bet is to get on the phone, get multiple opinions, multiple quotes, and make decisions on the type of build before pulling the trigger.

I can bet if inflation runs then Boston prices skyrocket, but I doubt Austin does.

If you kept the property, and accumulated the CF/yr, it would take you 25 years to get that same equity that's sitting, frozen in your property.Also, if you cashed out and used that same equity as a DP on different RE, at 20% DP, that equity would buy you $2M in PV, not just $700k,...and, I'd be willing to bet, you could find new RE that would have a yearly CF well over $20k/year.On top of that (remembering my initial statement above), any appreciation applied would be applied to $2M, not just $700k. 

I just provide DTV and internet.

The Midwest is probably your best bet for a number of reasons.
