As regards longtime defects, I guess I've just mentioned a broken window pane and not having painted for many years. Both are necessary items for the rental of the property. We promised the tenant we'd sort out both. I can't imagine either of those could fit into the 'evasion' category. At the same time, I had quite a bit of prep to do before i could rent it out - and there were costs that came with that. Of course, I'm out of pocket for that and can't claim it. That's just the system that's in place so I guess I just have to accept that.Ok, sorry, I see your point now.
Some of the ideas you've mentioned (eg claiming tax deduction on repair of longtime defects) are in the tax evasion category though.
