basis tracking on 26 months of my own labor, where does the line fall
I'm two years out of a different career and running the numbers on a live-in flip before I commit, and the piece I can't resolve is basis.
Say purchase at $265,000, and over 26 months I put in $58,000 of materials and subbed out $34,000 of electrical, plumbing and roofing. I do the demo, framing, tile, cabinets and paint myself. Call it 900 hours of my own time. Projected sale $430,000.
Gain against a $92,000 documented basis addition is roughly $73,000 before selling costs, comfortably inside the single-filer exclusion, so on paper the tax question is moot. My problem is that I'm treating my 900 hours as free, which makes the whole deal look better than it is. If I priced my labor at even $35 an hour that's $31,500 of value I created that never shows up as a cost anywhere, and it also can't go into basis. So am I actually making $73,000 or am I making $41,500 and paying myself badly?
And a second thing. If the exclusion covers the gain anyway, does careful basis tracking matter at all on a deal this size, or is it only insurance against the sale coming in higher than I think?
