Lindsay Lohan -- I Can Barely Pay My Rent!

Lindsay Lohan's financial situation is so dire, she is struggling each month to pay the rent on her Beverly Hills mansion ... TMZ has learned.

According to our sources, Lindsay has been scraping together the money to pay her $8,000 rent. We're told Lindsay signed the lease on the home back in February ... when her career was on the upswing and the money seemed to be rolling in.

But according to our sources, when Lindsay's finances took a turn for the worse (like when the IRS seized her bank accounts) she began doing whatever she could to make rent each month, often hitting up friends for money.

Lindsay tried to get out of the lease and move out early, but we're told the owners of the home told LiLo the penalty for breaking the lease was MASSIVE.

So Lindsay is making it work until the lease is over in February and LiLo is telling friends she'll then look for a place in New York.

Maybe Dina needs a roommate.
