As long as you attribute it to the humble author :)

What key features or attributes do you consider when making your decision?

We attribute this due to slow market and interest rates.

In the example you were using, there would be a $100,000 that was attributed to the building itself as 27 and a half years if it’s residential, 39 years if it’s commercial, and in this case commercial means like an office building or a strip mall or something like that.

Refi after construction.These numbers consider only the portion of costs of the HEL attributable to the land purchase, not the payoff of the HELOC (which we took out to buy the Seaside condo).Cash In:                     $66,166 (Cash, 1 year of debt service of HEL, debt service of const. loan, furnishing)Amount Financed:      $548,000 (home equity loan + construction loan + closing costs)Total Cost of build:     $614,166ARV:                               $850,000 (or rather "after construction value")Refi                                $637,500 (75% of value + closing costs)                                        Cash Out                       $89,500New payment             $4500/month (54,000/year)Estimated Cash Flow (pre-tax numbers, so actual mileage may vary)airBNB year 1:            $70,000     (net income $16,000)airBNB year 2:            $100,000   (net income $46,000)airBNB year3+:           $120,000   (net income $66,000)ROI (construction year):    0ROI Year 1 of STR:              24.2% ROI Year 2 of STR:              69.5% ROI Year 3+ of STR:            99.7% Did I calculate these ROI numbers right? 

If you look at the transaction as a whole, you took a massive deduction one year, likely paying no tax and losing tax attributes, then in the final year, you pile all of that deduction back on top as ordinary income in a year you likely have higher income....I am not saying it is a bad idea, someone who doesn't have much income will certainly want to weigh this possibility and consider their timing. 

You miss one key attribute of rent control in your analysis.  

Accelerated depreciation reduces the adjusted tax basis, and amounts attributable to §1245 property are subject to ordinary income recapture, while §1250 depreciation on the remaining real property may be subject to unrecaptured §1250 gain taxed at a maximum 25% rate.

Does the property distributed retain its tax attributes in the hands of the partners post-distribution?
