Another example illustrates that an 8 year old addition/remodel didn't make much total difference to their computational approach compared to the 41 year old basic residence, in case that age was an issue. I did the remodel in 2013 for $150,000. The basis for was computed as 19/365 => 0.052 x $150,000 = $7808. That compares more favorably to the TTax result of $7815 for only a minor difference compared to the $1297 smaller result they got for the 41 year old house above (I mistakenly said they got about $700 more) and suggests there maybe was a property age explanation involved. But then I calculated the deduction as $7808/27.5 yrs = $284. Yet TTax got the vastly different deduction result of $36 which was lower than mine by 8x versus the 10x difference from the 41 year old property. So from an age standpoint the overall differences were not that much. Incidentally, in case the type of rental makes a difference, my rental was to NBC Universal Content Productions for 2 episodes of a 5 episode Hulu movie film. The period was from 11/24/21 to 12/31/21. So while the span was 38 days, they were only in my house for a total of 19 days sporadically spread over that time. The total rental period extended into 2022 for another 8 days spread over 1/11/22 to about 2/23/22 when they filmed the remaining 3 episodes. Since that period was less than the 14 day exclusion period I don't believe I will have to pay taxes on it in 2022.
