claiming active participation this year - previous losses?

[Jeff Thompson]

Hi everyone,
Just a simple question I can't seem to find the answer to. Previous years I did not claim active participation and have accumulated a few thousand in losses. Last year I had losses yet again, but spent a lot of time fixing the property and finding renters myself - needless to say I actively participated.

Can I claim all the losses last year and the previous years or just the losses I took last year against my normal income? The total losses are less than 25k and my AGI is under 100k.

Thanks,
Jeff
